toma witb operculate forms, and until further evidence sball shew 

 sucli a vievv to be untenable, we may regard the present as one more 

 of tbe peculiar Cyclophoroid genera vvbich seem specially to charac- 

 terize tbe Indian and Bornean provinces.

Tbis species appears to be more depressed in the spire tban any 

 otber of tbe genus, except perhaps the Bornean A. spiracellum, 

 A. Ad. and Reeve. Its nearest Indian ally is A. strangulatus, Hutton, 

 and in size itis intermediate between that species and A. stylifer, Bens. 

 It belongs to tbe section Charax of Benson, baving a wide strangu- 

 lation bebind tbe peristome, crossed by a swollen ridge, which, liovv- 

 ever, in A. expatriatus never presents tbe sharpness so remarkable in 

 A. stylifer and líeles, but is ratlier a broad tumid space separating 

 two narrovv constrictions. The sutural tube is variable in len"th 

 sometimes being nearly as sboit as in A, slrangulatus, in otber 

 specimens as long as in A. stylifer ; tbe latter being the usual case, 

 tbe former tbe exception, but botb occur in perfectly l'resb and full 

 grown specimens.
