The peciiliar distortion of the last whorl, whieh first descends 

 after the constriction, and is again deflected towards the aperture, 

 separates this minute species from all forms known (von Mol- 

 lendorff). 



Bukit Pondok. 



A. PARVULUS, von Moll. I.e. 



Another minute form, still smaller than the last to which it 

 appears somewhat related. It differs, however, in the constriction 

 being nearer the aperture, almost regular last whorl, the broad 

 outer and very prominent inner peristome (von Moll.). 



Bukit Pondok. 



A. MiCROCONUS, von Moll. I.e. 



By the conical shape, the regular last whorl and the reticulate 

 sculpture this small species is very well distinguished from all 

 Indian Alyccei.
