Several specimens of Herpobdella lineata were collected bv 

 Col. H. T. Pease at Lahore. This species is of wide distribution, 

 having been known to occur in Europe, Palestine, vSiberia, Mongolia, 

 North and Central America, iladeira and the Azores. 



The body in the preserved condition is elongate, flattened, 

 and of a uniform width for the greater part of its length, though 

 it is attenuated anteriorly. Large specimens are about 25 mm. 

 in length by 3 mm. across at the middle of the body. 



The colour in spirit is brownish-yellow without an}' trace of 

 the longitudinal stripes which are usually a conspicuous feature 

 of the colouration of the typical form. 



Somites i, ii and xxvii are uniannulate ; iii, iv and xxvi 

 biannulate ; v and xxv triannulate : the nineteen somites vi-xxiv 

 are complete with five rings, of which the last ring, although often 

 difficult to detect, is usually enlarged and divided transversely by 

 a superficial furrow. Occasionally the same subdivision is true 

 of the ring forming somite ii. 



There are in all four pairs of eyes of which the first and 

 second pairs lie in a transverse curved line in somite ii and the 

 third and fourth are placed in the first ring of somite iv. 



The male genital orifice lies on the second ring of somite xi ; 

 the female orifice is two rings behind the male, that is between 

 the fourth and the last ring of the same somite. 



The anus lies on the dorsal surface between somites xxv and 

 xxvi. 



15. Herpodfaella hexoculata, sp. nov. 

 (Text-fig, 3.) 



Numerous examples of this species, which appears to be new 

 to science, were collected by Dr. F. H. Gravely at Burhampur and 

 Hoshangabad, as well as by Dr. N. Aunandale from the Baitul- 

 gharib stream about eight miles from Nowshera in the Peshawar 

 District. 



The body in the preserved state is elongate, flattened, attenu- 

 ated anteriorly, bluntly rounded posteriorly, and of nearly similar 

 breadth posterior to the genital region. The posterior sucker is
