The recent opportunity of examining the faecal material of the water-scorpion Leccotrephes japonensis revealed a flagellate which had not previously been described from this host. After fuller investigation I found that it is a species new to science and should be referred to the genus Retortamona; I have named it Retortamonas leccotrephae sp. nov.The specimens of Leccotrephes japonensis used for studies on the parasitic flagellate R. leccotrephae, were collected from ponds on the outskirts of Shanghai, China. Apart from studying the living flagellates, at the same time stained specimens were prepared for the detailed study of various structures. These specimens were fixed either in Hollande's or in Schaudinn's fluid; stained in Heidenhain's haematoxylin, and destained in 2% aqueous phospho-tungstic acid. Moskowitz' (1950) modification of the Protargol impregnation method was also used for staining.In the living state, the flagellare has a slender, slipper-shaped trunk with an anterior dorsal flexure. The mean body size, exclusive of the posterior spike, is 12.8μ×4.8μ. The length of the slender posterior spike varies from 4.6μ to 15.8μ. There are two flagella of unequal length. The longer one extends forwards and lashes rapidly, causing the animal to rotate and to pursue a special course. The shorter flagellum is directed backwards and usually lies in the cytostome; it moves in an undulating manner.In fixed and stained preparations, the flagellates, not including the posterior spike, show a size-range of 6.2×2.2μto 15.6×5.4μ, with a mean of 11.9×3.4μ. The spike varied from 4.6μ to 13.6μ long, with an average length of 11.2μ. In general, a normal specimen of R. leccotrephae has a slender body; the anterior portion is narrower than the postcerior, and is markedly bent as shown in the living indivi.duals. The posterior portion of the body usually has a dorsal convexity, and the widest region is located near the two-thirds of the body-length from the anterior end.Near that edge of the nuclear membrane lying next to the cytostome, there are two minute, but separate, basal granules which give rise to the two flagella. The anterior flagellum is about as long as the body proper: much longer and more slender than the posterior flagellum, which usually lies within the cytostome, and commonly shows a series of two or three undulations; it often stains more deeply than the anterior flagellum.In hematoxylin preparations the nucleus is well stained, and clearly shows a layer of chromatin granules lying against the nuclear membrane, and a large central endosome, composed of a mass of granules.The cytostome is a large structure in this animal. It usually occupies about twothirds of the total length of the body proper. Along the margin of the cytostome there are two deeply staining fibres, the one on the right margin is longer than that on the left.Both the precystic forms and cysts of R. leccotrephae have been observed. The body of precystic individuals which are preparing to encyst, becomes smailer and rounds up; meanwhile, the chromatin of the nucleus condenses and forms a deeply staining endosome. The anterior flagellum is still disposed freely, and no cyst wall has as yet been formed. The border-line of the cytostome is distinct, but the two basal granules are visible only in favourable preparations. The mature cysts are nearly peanut-shaped, and are about twice as long as wide. In the stained specimens they are about 4.6μ long and 2.4μ wide. The cyst wail is of uniform thickness, and the nucleus is visible at one end. The other conspicuous structures within the cyst are the two flagella and the cytostomial fibres, which are arranged as they are in the trophozoite, except that the anterior flagellum is here directed posteriorly.DISCUSSION & SUMMARYIn its general body-form, R. leccotrephae closely resembles Mackinnon's R. agilis ('11) from crane-fly larvae, and also Corradett's R. gryllotalpae ('37) from the mole cricket, but it is especially like Geiman's R. caudacus ('32) from the aquatic larvae ef certain beetles.

红娘华蛐的身体结构,一般与Mackinnon所述的R.(Embadomonas) agilis和Corradetti所述的R.grillotalpae相似,特别近似Geiman所述的R.caudacus(图15,16)。但红娘华蛐有大约等於体长2/3的大胞口,和长於或等於体长的针状尾巴,而且无论在生活时或固定染色後,头部均向背後扭曲(此较图1和15)。这些特性,显然与过去文獻中所记载的种类不同,故(氵夬)定为蛐属——新种。

The examination of shrimps for trematodes has been carried on, but interruptedly, since 1950, and, in addition to the three reported species, Coitocaecum sp., Phyllodistomum lesteri (Wu, 1938)and Microphallus minus (Wu, 1938; Yeh and Wu, 1950), another new trematode was discovered in the ovary of the freshwater shrimps of Shanghai.

The examination of shrimps for trematodes has been carried on, but interruptedly, since 1950, and, in addition to the three reported species, Coitocaecum sp., Phyllodistomum lesteri (Wu, 1938)and Microphallus minus (Wu, 1938; Yeh and Wu, 1950), another new trematode was discovered in the ovary of the freshwater shrimps of Shanghai. Through careful morphological studies with both living and stained specimens, it was found that the present trematode is an unencysted metacercaria of the Genus Genarchopsis Ozaki, 1925. It shows profound progenesis with its internal structures, especially the fully developed reproductive system. Furthermore, the degree of progenesis is so marked that the worm is filled with light brownish eggs. This makes the third case of the progenetic phenomenon of the fourth trematode larvae parasitic to the freshwater shrimps, Macrobrachium nipponensis (de Haan), obtained from Shanghai.In comparing the morphological characteristics of the present species with those ofother Genarchopsis, i. e., G. goppo Ozaki, 1925, G. anguillae Yamaguti, 1938, and G. chinensis Tang, 1950, it was also discovered that the present species, with the presence of the seminal receptacle and difference in structure of both intestinal caecum and excretory bladder is by no means a duplicate of any of the above stated species. A new name, Genarchopsis shanghaiensis is, therefore, proposed.

本文把上海沼蝦的Genarchopsis shanghaiensis n.sp.作一描述,并与Genarchopsis goppo,Genarchopsis anguillae和Genarchopsis chinensis互予比较。新种主要的特徵:(1)具有受精囊;(2)卵有1长丝;(3)排泄管较长,而在腹吸盤前缘分枝;(4)腸支短,而在腹吸盤前缘合併;(6)睾丸左右相对并列。另外对本蟲早熟现象提出问题,加以讨论。

A new species of tapeworm Bothriocephalus gowkongensis sp. nov. is reported for Ctenopharyngodon idellus from Gowkong, near Canton, South China. The parasite is of great economic importance owing to the high mortality of the host caused by the infection and consequently heavy losses to the freshwater fishery industry. A preliminary note is given on the life cycle, which involves unidentified cyclops as intermediate hosts. The eggs are fully embryonated when laid and it is the first Bothriocephalus konwn...

A new species of tapeworm Bothriocephalus gowkongensis sp. nov. is reported for Ctenopharyngodon idellus from Gowkong, near Canton, South China. The parasite is of great economic importance owing to the high mortality of the host caused by the infection and consequently heavy losses to the freshwater fishery industry. A preliminary note is given on the life cycle, which involves unidentified cyclops as intermediate hosts. The eggs are fully embryonated when laid and it is the first Bothriocephalus konwn with this phenomenon. From a study of the variation in a large number of specimens of B. gowkongensis sp. nov., the author considers B. opsariichthydis Yamaguti, 1934 a synonym of B. achilognathi Yamaguti, 1934.SPECIFIC DIAGNOSIS: Bothriocephalus Rudolphi, 1808 emended Lühe, 1899, with generic characters. About 35-80 mm. in length and 0.5-1.2 mm. in width. Segments with or without distinct segmentation. Slight indications of secondary segmentation might occur in all segments. Immature segments broader than long, mature segments square and gravid segments longer than broad. Scolex large, fleshy, heart-shaped with distinct terminal disc and well-developed fleshy bothria. Inner longitudinal muscle bundles extremely weak and sparsely scattered. 50-90 testes. Cirrus immediately in front of vagina. Cirro-vaginal aperture median or slightly lateral between mid-line and posterior third of segment. Ovary near posterior of proglottid. Uterus convoluted, voluminous, and confined to median field. Uterine sac-may encroach on posterior border of preceeding segment or be placed some distance away. Vitellaria in complete circle in cortex. Like the testes, they are continuous from segment to segment. Eggs thin-shelled, operculated, fully embryonated when laid, measuring 33-38 53-54μType host: Ctenopharyngodon idellus.Habitat: Intestine.Type: To be deposited with the Department of Parasitology, Hun-Nan Medical College, Canton, China.Co-types: In author's collection, and to be deposited with the Depertment of Biology, Chung-Shan University, Canton, China.

1.文中记载草鱼腸中新种絛蟲B. gowkongensisn. sp. 是由广东九江採得的。 2.本蟲促使宿主的死亡率,使淡水渔业受到很大的损失。 3.由头槽絛蟲生活史的初步观察,发现它的卵排出时,已有发育完全的胚胎。 4.从研究大量新种标本的变化中,作者认为B. opsariichthydis Yamaguti, 1934是B. achilognathi Yamaguti, 1934的同种异名。
