702 Records of the Indian Museum. [Vol. XXII, 



found with Limnatis granulosa in Burma seems to be identical 

 with the present species. This leech, according to Harding, is 

 fairly common in India and is usually to be found attached to 

 the mud-turtle. 



The body is flattened and lanceolate, presenting a head region 

 which is separated from the trunk by a slight neck-like narrow- 

 ing. The dorsal surface exhibits a roughened appearance due to 

 the presence on each ring of numerous papillae, which are of various 

 size, the larger ones forming some five longitudinal rows, one me- 

 dian in position and two lateral in each half of the body. The 

 anterior sucker lies on the ventral side of the head, within the li- 

 mits of rings 1-6, the mouth opening near the anterior lit). The 

 posterior sucker is centrally attached and of a small circular shape. 

 The large specimen is about 8 mm. long by 3 mm. across at the 

 hind part of the body. 



The colour in spirit is grey or pale olive brown without any 

 trace of markings. 



On the dorsal surface seventy- one rings are counted in front of 

 the posterior sucker. Somites i, ii and xxvii, are uniannulate : iii, 

 iv, XXV and xxvi biannulate ; ^he twenty somites, v-xxiv, are 

 complete with three rings. 



A pair of eyes is generally placed in ring 3, but may occa- 

 sionally be shifted behind so as to extend over ring 4. 



The crop is provided with seven pairs of lateral diverticula, 

 a pair in each of somites xiii-xix, which are sometimes subdivided 

 distally. The last pair are, as usual, reflected posteriorly and 

 extend into somite xxii, giving ofi a secondarj', outwardly directed 

 diverticulum in each of the four somites xix-xxii. The anus is 

 situated on the dorsal surface between the last two somites. 



The male and female genital orifices are separated by two 

 rings, the male orifice being situated between somites xi and xii, 

 the female between the second and third rings of somite xii. 



In one case, attached to the ventral surface of the parent, 

 were frmnd numerous larvae which were about i ram. in length.

The collection contained a single specimen, which was found at 

 Nandi, Mysore State, attached to Limnacea acuminata and was 

 not in a state fit for close study and exact identification. The 

 body, presenting a dark grey colour in spirit, is fusiform and of 

 small size, being about 5 mm. in length. This leech may be 

 referred to Blanchard's Helohdella gracilis from Java described by 

 that author.
