314 H. H. Godwin- Austen — On the Helicidae collected [No. 4, 



Helicabiojt (Hopbttes) eadha, n. sp., Plate VIII, Fig. 4. 



Shell similar to that of H. Shillongensis. Animal rich ochre, sparsely 

 dappled with grey-black on the mantle and tail. 



Length 3-0", head to mantle 0-50", mantle 1-3", mantle to end of foot 

 10", tentacles 0-38". 



Hab. — Banks of Eadha Pokri* (tank) near Narainpur, Darrang Dis- 

 trict, — only one specimen was found. This is a close ally of H. hrunnea 

 and H. Shillongensis of the Khasi Hills, but differs in coloration and in 

 the markings of the mantle. 



Helicabion (Hoplites) cineeetjs, n. sp., Plate VIII, Fig. 2. 



The shell was not described when taken and it has since been mislaid. 

 The description of the animal, which is of more importance, I can give. 



Animal, when fully extended, long and narrow, colour dusky grey, man- 

 tle with a papillated surface slightly spotted, the spotting being coarser on 

 the body and tail. Tentacles short and blunt, with the oral ones very close 

 below them. 



Length 0'75", mantle 0-40". 



Hab. — On the Darpang river, foot of the Dana Hills, under old logs 

 in the forest. 



HELiCABioisr (Hoplites) Bttetii, n. sp., Plate VIII, Fig. 6. 



Shell dull white, very horny in texture, the apex scarcely developed, 

 outline rounded above. 



Major diam. O30". 



Animal grey-brown in colour, the largest measuring as follows : — 



Mantle to head O40" ; mantle O80", mantle to extremity of foot O50", 

 or total length when moving about 1"5". 



Hab. — The Borelli Tea Garden near Tezpur, Assam, discovered by Mr. 

 J. Burt, after whom I name it, and who found it abundant on the bark of 

 trees during the rains (July). It is of the true typical form of Hoplites, 

 but in its very rudimentary white, horny shell it is quite distinct from any 

 of the other species I am acquainted with. 



These molluscs are abundant during the rainy season in this part of 

 India, but are hard to discover in the cold weather, and only then under 

 stones and logs in damp low situations. In July I found H. croceus very 

 plentiful just above Teria Ghat, and I observed them, when I was hunting for 

 butterflies, crawling about over the tall grasses 12 feet from the ground. 



Testacelba ? Dikbangensis, n. sp., Plate VIII, Fig. 7. 

 Shell dextral, ovate, very flat, solid, the lines of growth well marked, 

 with a dark brown ej^idermis, the apex cap-shaped, rather produced, and 

 much curved.
