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

 piece of paper, on which was written the following notes: 

 'From the branches of a Pepul tree, in scars and other shal- 

 low cavities, opposite the Deputy Commissioner's Cutchery, 

 Silchar, 3.4. '81. 



' ' ' Only one pair of short, thick, blunt, sausage-shaped ten- 

 tacles, 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.' Sent to me for 

 determination by Dr. N. Annandale, from the Indian Mu- 

 seum. The type-shell figured, with the remaining specimens, 

 will be returned to that Museum" (G.-A.). 



Godwin-Austen does not make any comparison with P. 

 orcula, which is a little larger, but otherwise seems similar. 



9. PUPISOMA PULVISCULUM (Issel) . Vol. Ill, pi. 42, figs. 55-57. 



Shell very minute, nearly covered perforate, corneous-buff, 

 translucent, obliquely striatulate under a strong lens. Spire 

 convexly conoid, the apex flattened; whorls 4, convex, sep- 

 arated by a deep suture, the last whorl descending a trifle to 

 the aperture, convex at base. Aperture strongly oblique, sub- 

 angular at base ; peristonie acute, the right margin regularly 

 semicircular, columellar margin nearly vertical, somewhat 

 straight, delicately reflected at the insertion. Alt. 1, diam. 

 mm.; length of aperture % mm. (Issel). 



Borneo: State of Sarawak (Beccari) ; Labuan (Everett).

 Malac. Soc. Lond., iii, p. 29. 



Possibly distinct from P. orcula by having 4 whorls in a 

 shell of smaller size, if the measurements are correct. Noth-
