eggs are small, of an oval shape, with a dark-brown shell. 

 Parasitic in the intestine of Amphibia. Typical species: Ganeo 

 glottoides Klein 1905 ^) from Eana hexadactjjla (India). 



In the collection of Prof. D o g i e 1 and S o k o 1 o v there is 

 one form of Trematodes, which is closely related to the species 

 Ganeo glottoides Klein 1905. The resemblance between the 



African and Indian forms is so striking — even in such 



slight 



characters as, e. g., the length of the pharynx, the length of 

 the oesophagus etc., to say nothing of the size of eggs that 

 I had to refer the African form also to the species Ganeo 

 glottoides Klein. The only character that distinguishes my 

 parasite from that of Klein is a difference in the position 

 of the genital glands. This peculiarity justifies me in separa- 

 ting my parasite as a representative of a new variety of the 

 species Ganeo glottoides Klein 1905 which I name var. 

 africana nova var.

The new variety of Ganeo glottoides Klein 1905 — var. 

 africana nova, var., as mentioned above, is nearly in all 

 details of its organization identical with the species des- 

 cribed by Klein from India. I shall not give a detailed 

 description of my variety, not wishing to repeat K 1 e i n's mas- 

 terful Avork, but shall point out those peculiarities in the 

 structure of the African form which lead me to distinguish 

 it as a new variety. 



In comparing the African parasite with the Indian it is 

 first of all noticeable that the intestinal trunks in the former 

 nearly reach the hinder end of the body, whereas in the lat- 

 ter the blind extremities of the intestine are far from the 

 end of the body (see fig. 6 in Kle i n's work). However, this charac- 

 ter is of no specific value, as in several specimens of Ganeo 

 glottoides Klein observed a different length of the inte- 

 tinal trunks. The difference in the arrangement of the ge- 

 nital glands is much more serious. In the Indian species 

 the anterior testis is situated immediately behind the bifur- 

 cation of the intestine, and the posterior testis lies anteriorly
