the other species of Haemopis. The shallower furrow is the one 

 separating some rings of somites vii-xi and xxvi, as is shown in 

 text-fig. 7 by the broken line. 



The arrangement of eyes is in agreement with that of Haem- 

 opis sangnisuga. 



The male and female 

 genital orifices occupy a 

 position respectively bet- 

 ween the last two rings of 

 somites xi and xii. 



The nephridial pores 

 are situated in the furrow 

 between the second and 

 third rings of the middle 

 seventeen somites 



The anus is located on 

 the dorsal surface just be- 

 hind the last ring of the 

 trunk. 



This leech appears to 

 he nearly allied to Haemopis 

 sanguisiiga, but may be 

 distinguished from it by the 

 different annulation of the 

 body. 



Genus Myxobdella, Oka. 



26. Myxobdella annan- 

 dalei, Oka, 1917. 



There was in the collec- 

 tion a single example which 

 may be identical with Oka's 

 Myxobdella annandalei from 

 Hong Kong described by 

 that author. The specimen 

 was found in a hill stream at 

 Yercaud, Madras. 



The body is smooth on 

 the whole, entirely devoid 

 of papillae and almost uni- 

 formly broad for the most 

 part, though it tapers off considerably in front. The dorsal 

 surface is convex throughout while the ventral is nearly flat. 

 The posterior sucker is circular in outline and in the preserved 

 state is entirely hidden when viewed from above. The specimen 

 measured 17 mm. in length and about 4 mm. in breadth at the 

 middle of the body. 



As has been described b}' Oka in detail, the most conspicuous 

 f the external features is that the body is divided by deep furrows
