 separable. It is also very near M. nevilli, Brot.

6 Sarawak [typical] ; coll. Prof. A. Issel. 



Not at all like M. Brot's fig. 5, fairly represented by his 5 A., 

 perhaps, the real M. gemmulata of Reeve. The thick substance, 

 plannlate whorls, and developed longitudinal sculpture seem 

 the best characteristics of the form.

Perhaps scarcely separable from subspecies fontinalis, Phi- 

 ,lippi. Some of the above exactly resemble the type figure.

var. subunifascialis, nov. [? dist. sp.]. 



2 Andamans [type var.] ; coll. F. A. de Roepstorff, Esq. 



A very remarkable form; will perhaps prove specifically separ- 

 able. I should have classed it as a var. of M. unifascialis, 

 Mousson, from Java, but for the entire absence of longitudinal 

 sculpture and the rather more convex upper whorls ; the spiral 

 striation is more or less obsolete on the upper portion of the 

 whorls, imparting a very characteristic appearance to the shell ; 

 basal band round the columella not visible within the aperture. 

 Long. 19, diam. 6 mil. ; anfr. 8|.
