Dohrni, its nearest allied form being rather comes than per- 

 versus.

This partakes of the characters of botli comes and perversus, 

 but is easily separated by the coloration of the last whorl and 

 by the smaller aperture.

This varies in form and coloration, and approaches very 

 near to polymorphus, but can be separated by the white tract 

 behind lip and the greyish-brown bands below and encircling 

 the suture of upper whorls. 



Group of A. javanicus.

Chiefly distinguished from perversus by its coarse oblique 

 striation.

Like typical palaceus, but with a dark reddish-brown band 

 encircling the last whorl at the periphery. Martens gave 

 this name to a specimen with a pale salmon-pink ground- 

 colour, but sometimes it is pale yellow.

The type is a more elongated form than typical palaceus, 

 of more solid growth, lighter colour, and has a smaller aper- 

 ture ; but with the series before me (the pick of a very large 

 number of specimens) I am unable to separate this from 

 palaceus,
