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。

From February 1954 to February 1955, we have continuously studied the morphological changes of the reproductive glands of the Oncomelaniid snails once monthly by dissecting and serial sectioning. The snails used for this study, measuring within the range of 7.1 to 3.0mm., were collected from the banks of Ching-San River, Chungking, Kiangsu.The results of this study show that the reproductive glands of the Oncomelaniid snails, either male or female, exhibit periodic changes with hypertrophic and atro-phic phases...

From February 1954 to February 1955, we have continuously studied the morphological changes of the reproductive glands of the Oncomelaniid snails once monthly by dissecting and serial sectioning. The snails used for this study, measuring within the range of 7.1 to 3.0mm., were collected from the banks of Ching-San River, Chungking, Kiangsu.The results of this study show that the reproductive glands of the Oncomelaniid snails, either male or female, exhibit periodic changes with hypertrophic and atro-phic phases alternating with each other.From November to May of the following year, the ovary of the female snail is in the phase of hypertrophy. It is large, thick and prominent, containing a large number of eggs in the different stages of development. In June, some of the ovaries become smaller and thinner. From July to August, the ovary enters the atrophic phase, diminishing remarkably in size and containing only a small number of the primary oocytes. Beginning from September, the ovary shows signs of recovery and in October resumes its egg-producing capacity.From experimental and field observations, the female Oncomelaniid snails lay eggs from November to July of the following year, laying a large amount of eggs being laid from February to June, but no eggs at all from August to October. These findings are in agreement with the periodic changes of the ovary as shown above.The periodic changes of the testis, involving both hypertrophic or atrophic phases, appear about 4 months earliec than those of the ovary. From January to April, the testis appears atrophied, but in the vas deferens a large amount of spermatozoa is stored up. From May to August, the testis recovers gradually, being capable of producing spermatozoa, and from September to November it enlarges greatly, producing a large amount of spermatozoa. In December the testis again inclines to atrophy.From the field study, we know that the copulation of the Oncomelaniid snails takes place throughout the year, but more often during spring and autumn. Microscopic sections show that spermatozoa are found present in vasa deferentia every month, and in a greater amount in winter, spring and autumn. This would assure the fertilization of the eggs during the main copulation season.

从1954年2月到1955年2月,我们每月应用外形解剖结合组织切片的方法,观察了日本血吸虫中间宿主——钉螺生殖腺的周期变化。 雌螺卵巢在一年内有一度的周期变化。从11月到第二年5月,卵巢呈丰满而多卵的状态;6月卵巢趋向萎缩;7、8月卵巢萎缩,内仅含有少量的幼稚卵细胞;9月卵巢开始趋向丰满;10月卵巢逐渐恢复丰满的状态。卵巢全年周期变化的过程与镇江地区钉螺的产卵情况基本上相符合。 雄螺精巢在一年内也有一度的周期变化,但较卵巢要提早4个月左右。1—4月精巢呈萎缩状态,但输精管中尚储存有大量精子。5—8月精巢逐渐恢复原状,能产生少量精子,此时输精管中的精子还少。9—11月精巢特别丰满,含有大量精子。12月精巢开始萎缩。在9月以后,输精管中即逐渐储满了精子。输精管内精子储存的情况与南京及杭州地区钉螺的交配情况基本上相符合。

Testes large, oval-shaped with smooth edge, situated side by side, with the anterior edge extending to the posterior half of the acetabulum, nearly equal in size, left one 0.405-0.516×0.373-0.470 mm, right one 0.421-0.518×0.324-0.486 mm. Cirrus sac located between intestinal fork and acetabulum, 0.259-0.388×0.146-0.178 mm. Cirrus conical-shaped, extending from the genital pore. Genital pore situated behind the intestinal fork.Ovary transversely ovoid, situated behind left testis, 0.130-0.194× 0.130 -0.259mm. Seminal receptacle 0.074mm. in diameter. Shell gland 0.178 × 0.194mm. Vitellaria beginning at the posterior end of the testes, its length about 1/5 of the body length. Uterus well developed, filling up the posterior half of the body. Eggs numerous and small, black-brown in color, 36-47 × 25-32μ.Habitat: Liver of sheep, Capra hircus Linne.Locality: Kunming, China.Date: 1940.Type and paratype: Nankai University, Tientsin,This species resembles P. semifuscum Looss, 1907 very closely, but differs from the latter in the body size, the shape of the testes, the presence of the cirrus and the final host.This is the fourth species of Platynosomum found to be parasitic in mammals and is the first species of this genus heretofore recorded from China.

山羊扁体吸虫Platynosomum capranum sp.nov.寄生在昆明的山羊肝脏内。这一新种吸虫为第四种寄生在哺乳类体内的扁体吸虫,也是扁体吸虫属在我国的初次记录。 虫体形小,体长平均3.538毫米,阔平均1.088毫米。表皮光滑。精巢形大,排列於腹吸盘後半部之後,阴茎囊延长,囊内藏有贮精囊之外,前端还有一个锥形的阴茎,长0.126—0.158毫米,常伸出於生殖孔之外。生殖孔位於肠叉之後。卵巢位於左精巢之後。具受精囊与卵壳腺。卵黄腺的长度约为体长的1/5。 本新种的形体与P.semifuscum Looss,1907相似。由於它寄生於哺乳类山羊的肝脏里,体形较小、精巢边缘平滑无叶,阴茎明显;这些特徵显与P.semifuscumLooss相区别,因此认它为扁体吸虫属中的一个新种。 文中把斯克里亚平氏所确定的11个独立种与本新种一起,作了一个检索表;但是几个未能确定的待考种与在有袋类体内发现的一个未定名的种,并未包括在表内。
