MOLLUSCA or INDIA. 303 



Nearly every animal examined contained three embryonic 

 shells, some in an advanced stage of development, showing 

 the apex of the shell ; compared with the parent animal they are 

 very large, and being pale-coloured were very apparent. During 

 the height of the rains they must be extremely prolific, and no 

 doubt are crowded in colonies together, as I have seen some 

 species, such as Georissa, &c., in the humid valleys of the Kliasi 

 11 ills. Mr. Collett took them off orange-trees in September, 

 1899, in the bungalow garden, on the Binoya Estate. 



I would call attention to the jaw and radula of Pupisoma 

 mlccyla being so similar to those parts of Philalanka thivaitesii 

 (Vol. II. Plate CXII. figs. 1-1 o), and this has led me to place the 

 genus in the same subfamily Thysanotince, after PhilcdmiJca, 

 vide p. 188, Vol. II. 



It is also of interest, going outside the Indian Eegion, to note 

 that the same type of jaw and radula is found in the South African 

 genus Afrodonta, type-species bilajnellaris, Melv. & Ponsonby,.

Pupisoma cacharica, n. sp. (Plate CXXXII. fig. 4.) 



Locality. Silchar {J. Wood-IIason). 



Shell scarcely perforate, globosely conoid, very tumid, corneous ; 

 sculpture, spiral striation, crossed by fine close thread-like ribbing; 

 colour pale umber-brown ; spire moderately high, conic, apex 

 blunt ; suture open ; whorls 3|, rapidly increasing, very convex ; 

 aperture nearly circular, oblique ; peristome thin, columellar 

 margiu perpendicular, reflected. 



Size : major diam. 1-33 ; alt. ]"5 mm. 



The tube containing some 50 shells was wrapped up in a piece 

 of paper, on which was written the following notes : — " Prom the 

 branches of a Pepul tree, in scars and other shallow cavities, 

 opposite the Deputy Commissioner's Cutchery, Silchar, 3.4.81. 

 Only one pair of short thick, blunt, sausage-shaped tentacles, at 

 the upper extremity of which the black eye-spots- are placed. 

 Animal semitransparent, greyish, milky m bite below, above grey ; 

 retractor muscles of tentacles very plainly visible through in- 

 tegument. No tail-gland." Sent to me for determination by 

 Dr. N. Annandale, from the Indian Museum. The type-shell 

 figured, with the remaining specimens, will be returned to that 

 Museum.

 3 b (radula).) 



Locality. Kandy, Ceylon, on palm-tree {Mrs. J. Longsiaff).
