Family Herpobdeijjdae. 

 Trocheta quadrioculata, sp. nov. 



Glossiphonia heteroclita (Linne). 



Syn. : Hirudo heteroclita, Linne, 1 761. 

 H. hyalina, O. F Miiller, 1774. 

 H. trioculata, Carena, 1823. 

 Clepsine hyalina, Moquin-Tandon, 1826. 

 Glossiphonia heteroclita, Muquin-Tandoii,i846. 



Localities : — Loitan Tank, Yawnghwe Valley. One specimen. 



Marginal zone, Inle Lake. Three specimens, from Pachylabra 

 maura (Reeve, Mollusca Gastropoda, family Ampullariidae). 



These are all small snecmens, measuring only 6 mm. in 

 length and 3-4 mm. in width. Preserved in alcohol, the specimen 

 from Loitan Tank is almost whke; those from the other station 

 are somewhat darker. In both cases there is no indication that the 

 animal was striped or spotted during life. 



The identification of these specimens is chiefly based upon the 

 disposition of the six eyes, so characteristic of the species. They 

 are arranged, namely, in three groups of two eyes each, one anterior 

 median and two posterior lateral, in such a way that the animal, 

 when examined superficially, appears to possess only three eyes. 

 So far as I could ascertain, the constitution of the abbreviated 

 somites at the anterior and posterior extremities of the body 

 agrees fairly well with the minute description of American speci- 

 mens of Glossiphonia heteroclita given by Castle (6). 



From Glossiphonia ceylantca Harding (9), some examples of 

 which, according to Kaburaki (ic), appear to be identical with this 

 species, the specimens examined by me could be easily distin- 

 guished by comparing the position of the eyes. In Gl. ceylanica 

 the second and third pairs of eyes are not so close together as in 

 GL heteroclita, but are separated by at least one ring. 



Glossiphonia inleana, sp. nov. 



Locality : — Fort Stedman, Inle Lake. Numerous (about 60) 

 specimens, from a tortoise (Cycle nvs dhor shanensis Annandale). 



Shipe and dimensions. As shown in fig. 1 the form is 

 rather slender for a Gloss ip how' a, being from 3 to 4 times as long 

 as wide in moderately contracted specimens. The broadest part 

 lies posterior to the middle, from where the body tapers very 

 gradually toward both ends. Both the dorsal and ventral surfaces 

 are convex, so that the body is somewhat lens-shaped in cross 

 sections. The lateral margins are sharp and serrate. The posterior 

 sucker is of moderate s ze, circular in outline. Except the shape 

 of the head, which does not project toward the side, this species 

 closely resembles Hemic/epsis marginata, with which it also shares 

 the habit of living as an ectoparasite on tortoises. 



The largest individuals measuie about 9 mm. in length and
