It is doubtful what these can be; they were not included among 

 those which cnrae from Calcutta. I hear (October 1914) they 

 cannot be found in the Museum, owing to shifting of collections.

Original description ; — " Shell closely umbilicated, turbinate, 

 horny or grey, with distant well-marked costulation on the upper 

 wliorls, smooth below, finely ribbed on swollen part of the whorl, 

 still more finely on the constricted portion ; spire subcoiioid ; 

 whorls 4, the last slightly swollen, then constricted and slightly 

 swelling again towards the peristome, which is longitudinally 

 undulated; sutural tube moderate; aperture oblique, waved; 

 peristome thickened, expanded a 'little, double, with four deep 

 undulations on the outer margin and one less developed on the 

 lower, the first undulation forming a deep notch on the peristome 

 near its junction with the last whorl. Operculum as in A. cris- 

 jpatas mihi. 



* The t)pe of this species is in the Natural History ]\ruseiini,and T hare 

 been able to make a drawing of it. Mr. Preston tells ine it is named after a 

 collector, who has recently been in Assam. It is allied to A. sfoUcskii, miiii, 

 in the form of the peristome, but is more openly umbilicated, and the 

 sculpture is very different — not by any means so strong. I would thus 

 describe it : — "Strong costulation next the base of the sutural tube extending 

 forwards as far as tlie constriction, backwards it becomes rapidly finer, long 

 before the end of the sutural tube is readied, it is close and beautifully 

 regular on the rest of the shell, and within the umbilicus."
