Long. Ij, diam. 1 mill. 



Hab. Ceylon : Matelle (Layard), "Watawala (Collett). 

 Benson recognized its affinity to P. orcula, stating that P. mic- 

 cyla is smaller, destitute of the peculiar sculpture of that species, 

 and distinguished by its very obtuse apex and by the formation of 

 the columellar lip. Lt.-Col. Godwin- Austen, who received from 

 the late O. Collett a number of shells with the soft parts preserved 

 in formalin, states that miccyla is smaller than lignicola, has a 

 greater number of whorls, and is more attenuate than orcella* 

 while the transverse striso of the cuticle appear to be more 

 regular. These specimens enabled him to examine and figure the 

 jaw and radula, and thus to fix the systematic position of the 

 group.

Pupisoma cacharica, Godwin- Austen, Land & Freshw. Moll. India, 

 ii, 1910, p. 303, pi. 132, fig. 4. 



Original description : " 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,

Major diam. 1'33, alt. 1*5 mill. 



Hab. India : Silchar ( Wood-Mason). 



The species is based on specimens sent for determination by 

 Dr. Annandale from the Indian Museum. They were accompanied 

 by the following notes : " From the branches of a Pepul tree, 

 in scars and other shallow cavities, opposite the Deputy Com- 

 missioner'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 white below, above grey; retractor muscles of 

 tentacles very plainly visible through integument. No tail- 

 gland."

 distant costulation ; colour pale brown ; spire depressed ; whorls 3,
