A single example agreeing in all respects with the type 

 from the Angrias Bank, west of Bombay. 



Marginella angustata, Sowerby. 



Hah. Oflf Coromandel coast, 41 fath. 



The specimens from this locality are much smaller than the 

 types figured by Sowerby, the average length being only 

 13-14 mm. They differ also in exhibiting a small spire 

 consisting of a few whorls, which, in the large form, becomes 

 concealed by callus.

Hah. Gulf of Martaban, Q7 fath. 



It seems to me doubtful whether the shell figured by 

 "Weinkauff is the same species as that described by Sowerby. 

 The type of ohtusa in the British Museum is much larger 

 (24 mm.) and narrower, has a flatter spire, and the plicae 

 on the columella seem different. I have been unable to find 

 any reference to this species by Dunker before the year 1882 

 in his ' Index Moll. Maris Japon.' p. 57. The quotation by 

 Weinkauff '^ Mus. Godeffr. Cat. 3 (1871)'' is evidently 

 erroneous, as that Catalogue was issued in 1866. Tryon, 

 in his monograph of this species (Man. Conch, vol. v.), has 

 merely followed Weinkauff, giving the same reference to the 

 Godeffroy Catalogue ; and Pilsbry also (Cat. Marine Moll. 

 Japan, p. 24) throws no light upon the point.
