1. All kinds of colonies of Volvox africanus were found in great abundance during the first two weeks of May, 1933, from a pond in Nanking.2. The smallest colony is much smaller than that recorded from Africa and the Philippine Islands.3. The somatic cells are not connected by protoplasmic filaments in adult colonies.4. Asexual colony usually contains from two to six daughters symmetrically arranged in pairs according to size on opposite sides of the polar axis.5. Sexual colonies of different kinds are developed from the asexual mother either singly or in combination with other kinds and asexual daughters.6. Parthenogonidia develope very early in young embryos long before the latter become matured and escaped from the mother colony. 7. During the early development of parthenogonidia, at least from first to fifth or sixth divisions, no growth of the whole embryo takes the place while the number of cells increases.8. Spermatogonia attain fully-grown size and begin to divide before the time of the birth of the colony.9. The development of spermatogonium consists of seven successive divisions in forming a bundle or platelet of one hundred and twenty eight spermatozoa or microgametes.10. The number of ovaries in a female colony varies from twelve to fourty six. Generally, the larger the colony, the more the ovaries developed.11. Risexual colonies contain only two or three spermatogonia in addition to fourteen to twenty seven ovaries.12. In general, specimens recorded in Nanking are identical to those from the tropical regions such as Africa and the Philippine Islands.

關於菲洲團走子之分佈,按記載所及。僅限於菲洲,菲列濱,南印度等熱带區域。今在南京發現,於地理分佈上實為一新記錄。此種團走子在羣體成熟之後,其體質细胞間,並無原生質線交相聯絡。無性羣體每含有二至六大小不同成對均置之無性幼羣體。幼羣體在脫離母體以前,往往含有第二代幼體。各種有性羣體,亦自無性母羣體中發達而成。雄性羣體,皆为橢圓形,而較其他羣體為小。雌性羣體中之卵或大配子约有十二至四十六。雙性羣體只含有二或三精原细胞,及十五至二十七卵或大配子。孤性生殖细胞在幼羣體内即發生。當最初五或六次分裂時,细胞雖增加,而幼胎並不長大。精原细胞经七次連續之均等分裂,而成一束一百二十八精子或小配子。

Although there are records of the occurrence of Echidnophaga gallinacea (Westwood 1875) inChina, yet its exact locality is not clear.

Although there are records of the occurrence of Echidnophaga gallinacea (Westwood 1875) inChina, yet its exact locality is not clear. The discovery of the present species constitutes the secondspecies of Echidnophaga in China. In July 1953, a single specimen of a male flea was collected fromChi-tang, Tibet, off Ochotona gloveri Thomas and is described here as Echidnophaga ochotona sp. nov. The morphological characters of this species is near to the cosmopolitan E. gallinacea. But thenew species differs by having 5 pairs of lateral planter bristles on the 5th hind tarsi, whereas E.gallinacea is provided with only 4 pairs. Minor differences are also present on the genitalia. Thereare variations in the numbet of lateral planter bristles on tarsi of the right fore- and mid-legs, eachwith 6 on the outer row. Other species with 5 pairs of planter bristles are E.bradyta J. et R. 1906 of Africa and E.macronychia J. et R. 1906 of Australia, but the new apecies differs from them by the characters of themale genitalia and claws respectively.

1.我国以往虽曾有过鸡食猬蚤的记录,但在地理分布上未得到明确。 2.1953年7月从西藏吉塘的葛氏鼠兔Ochotona gloveri Thomas体上采得雄蚤一只,经鉴定为新种,订名为Echidnophaga ochotona sp.nov. 3.本种的形态与分布普遍的鸡食猬蚤较近似,主要区别在于后腿第5跗节有5对侧跖鬃,而鸡食猬蚤的只有4对,另外在外生殖器上还有小的区别。 4.右前腿及右中腿第5跗节的侧跖鬃有变异现象,即外侧列各有6个,内侧列各有5个。

1. The present study includes observations on the morphology and life history of Haplorchis pumilio (Looss, 1896).2. The opinion of the present writer is to the contrary that skin glands of the metacercaria and adult can be used as a taxonomic character. The spines on the oral sucker of the cercaria are studied in detail and compared with observations made elsewhere.3. The size of the organs and their relative positions are closely related to the age of parasite and errors in calling old species of the genus...

1. The present study includes observations on the morphology and life history of Haplorchis pumilio (Looss, 1896).2. The opinion of the present writer is to the contrary that skin glands of the metacercaria and adult can be used as a taxonomic character. The spines on the oral sucker of the cercaria are studied in detail and compared with observations made elsewhere.3. The size of the organs and their relative positions are closely related to the age of parasite and errors in calling old species of the genus Haplorchis as new are due to overlooking of this fact.4. In contrary to the opinion of Africa who believed that visceral heterophycidiasis was due to abnormal relationship between host and parasite, the writer believes that those heterophyids which are not normal parasites to a particular host will be expelled instead, and only those which are normal to the host can bury deep in the mucosa, such as Haplorchis, and thus fause visceral heterophyidiasis.5. In view of the wide-spread habit of eating raw fish in Kwangtung Province, the writer believes that Haplorchis infection in man undoubtedly exists.

1.本实验对钩棘单睾吸虫(成虫、囊蚴、雷蚴、尾蚴)的形态及生活史作了详细的观察。 2.小榄白鲩鱼鳍上钩棘单睾囊蚴的感染率及感染强度都比较高。根据囊蚴的寄生状况,广东人对鱼类食品的烹调特点,文献中所记载的异形吸虫的致病作用以及在广州或其附近发现过异形吸虫的报告,估计广东居民中可能有异形吸虫病的存在,并推考了其所以未被发现的原因。 3.钩棘单睾囊蚴、成虫的腹面及背面都有皮腺。囊蚴腹面皮腺的总数及皮腺行数都不恒定,而各行之皮腺数也大多没有规则。 4.由小鸭及小白鼠中钩棘单睾成虫的寄生状态可知该吸虫在这两种小动物体中比较适宜的寄生部位是迴肠下段。寄生部位较深的成虫并无死亡的或发育不良的,所见到之死亡成虫绝大多数是混在排泄物中,也有少数见于粘膜表面。根据寄生虫一般的生活规律及本突验所见之寄生现象,对Africa氏等所述关于异形吸虫和宿主间平衡关系的问题进行了商讨。 5.在小白鼠的突验中发现感染天数不同的成虫,它们的虫体及生殖器官的大小可以有相当明显的差别。各器官和虫体前端间的相对距离可因成熟度和活动度不同而有比较显著的差异,尤以生殖器官为甚。本文对Kobayasi氏所定“新种”的根据进行了讨论。
