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, wlio received from 

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

 in formalin, states that micci/la is smaller than lignicola, has a 

 wreater number of whorls, and is more attenuate than orcella, 

 while the transverse .strite of the cuticle appear to be more 

 reo-ular. These specimens enabled him to examine and figure the 

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

 group.

Original description : — " Shell scarcely perforate, globosely 

 conoid, vexT 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

The species is based on specimens sent for determination by 

 Dr. Ainiandale 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 Ciitchery, 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, 

 grevish, milky white below, above grey; retractor muscles pf 

 tentacles very plainly visible through integument. No tail- 

 gland."
