r ngs 2 and 3 are transversel}' subdivided into two primitive 

 rings. 



As is seen from text-fig. 4, there are six pairs of eyes, of 

 which the first and largest pair occur dorsally on either side of 

 the median line in somite iii, while the other pairs are arranged sub- 

 marginalh' on the ventral side. The second pair lie in the second 

 ring of somite iv ; the third in the second rings of somite v, the 

 remaining three pairs respectively in the middle ring of each 

 of somites vi-viii. The last pair represents the smallest spots. 

 Occasionally just in front of the first pair occur a small pair of 

 provisional eye-spots. 



The male genital orifice 

 is placed on the middle ring 

 of somite xi : the female 

 orifice lies two rings behind 

 the male, that is between 

 somites xi and xii. 



The anus i-; situated 

 dorsally between somites 

 xxiv and xxv. 



As is apparent from the 

 above, the present species 

 seems to be closely related 

 to the genus Herpobdella, 

 but stands distinctly at 

 variance from it in the six 

 pairs of eyes, of which the 

 first pair occur dorsally in 

 somite ii, the other five 

 pairs laterally in each of 

 somites iv-viii respectively. 

 It appears to me that the 

 diiTerence is of sufficient 

 value to separate the two 

 forms generically.

Some representatives of 

 this interesting leech were 

 found at the base of the 

 Simla Hills near Dhuram-

The body is elongate,
