opens on the dorsal surface between the last two rings of the 

 Vjody. 



The male genital orifice is situated between somites xi andxii, 

 and the female orifice appears to open on the first ring of somite 

 xii. There are six pairs of testes, which are each placed in front 

 of the lateral diverticula of the crop. 



As is evident from the above, the present species is closely 

 allied to the preceding, Gl. weheri ; it is distinguished chiefly by 

 the different arrangement of the pigment pattern. 



10. Glossosiphonia ceylanica, Harding, 1909. 



This species is not peculiar to Ceylon, as some examples which 

 1 have examined were found in the neighbourhood of Lake Chilka 

 and at Rawalpindi. A full account has been given in my recent 

 paper (Joe. cit.). 



II. Glossosiphonia reticulata, sp. nov. 



(Text-lig. 2.) 



A single individual only, which seems to represent a new spe- 

 cies, was collected by Dr. B. Prashad at Jullundur, it having been 

 found attached to the mantle of a species of LaiiicUidens. 



The body in the preserved state is slender and broadest at 

 the posterior region, from which it tapers gradually towards the 

 anterior end. The head is marked off from the trunk by a slight 

 neck-like narrowing. The dorsal surface presents a roughened 

 appearance, due to the presence of papillae of various sizes, of 

 which the larger ones are arranged so as to form three longitudinal 

 rows, one median and two lateral. The posterior sucker is of a 

 circular shape and is almost centrally attached. The specimen 

 is 10 mm. in length, exclusive of the posterior sucker, l^y 2 mm. 

 across at the broadest part of the body. 



The body appears to comprise in all seventy-two rings, which 

 are grouped somewhat as follows : somites i and ii are uniannulate , 

 iii, iv, XXV, xxvi and xxvii biannulate ; and the twenty somites v- 

 xxiv complete with three rings. The papillae occur on almost all 

 of the rings. 



There are two pairs of eyes, of which the first and smaller pair 

 lie in ring 4, the second and larger in ring 3. 



The preserved specimen is of an olive grey colour due to irre- 

 gular pigment present all over in reticular distribution as well as 

 to the contents of the crop. 



The mouth opens in front of the centre of the anterior sucker. 

 The pharynx represents a long cylindrical tube, beginning just be- 

 hind the cephalic ganglionic mass situated in somite vii and ex- 

 tending behind into somite x. At the base it is supplied with nu- 

 merous ducts of the salivary glands which are widely distributed 

 in the anterior region. The crop is a distensible part of the digest- 

 ive tract and is provided with seven pairs of subdivided divertl-
