MELANIIDJ3. 225 







A smaller form, still more decollate, only 2 to 3 whorls re- 

 maining. They are exactly represented by M. Brot's above- 

 quoted pi. 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 Koepstorft, 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, but is 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. 



var. confusa. 



Melauia confusa, Dohrn, P. Zool. S. 1858, Ceylon, and Con. Indica, pi. 72,

I have never seen a specimen like M. Brot's pi. 14, fig. 9b.
