MBELANIIDE. 225 
A smaller form, still more decollate, only 2 to 3 whorls re- 
maining. They are exactly represented by M. Brot’s above- 
quoted pl. 21, fig. 16.

4 Great Nicobar ; coll. F. A. de Roepstorff, Esq. 
The only difference from the following two specimens seems 
to be that the apical sculpture is rather less developed. 
2 Katchall [?] ; coll. F. A. de Roepstorff, Esq. 
A very interesting form, fairly represented by the above 
figure, though the last whorl is relatively rather shorter still. 
The apical 8 whorls are very prominently and regularly longi- 
tudinally ribbed and spirally striated; last whorl, of course, 
smooth at base; of uniform dark olive-green coloration. I 
cannot help thinking they are from Great Nicobar like the 
preceding.

2 Samar [Philippines]; coll. Prof. C. Semper. 
One of these resembles Reeve’s fig. 26, butis only about half 
the size; the other exactly resembles Ceylon specimens of var. 
confusa, and I cannot help thinking may have got mixed by 
some accident.
