1878.] FROM THE ANDAMAN ISLANDS. 809 



in the length of the spire, the proximity of the series of granules, and 

 the size of them. 



A peculiarity of this species consists in the manner in which some 

 of the yellowish tubercules are as it were set in an irregular darker- 

 coloured ring, or, in other words, are surrounded by a dark line at 

 their base.

This species is undoubtedly an East- and not West-Indian species. 

 It has been found at the Sandwich Islands by Pease, and also at other 

 localities in the Pacific.

Hab. Solomon Islands. 



This species I described from specimens collected at the Solomon 

 Islands. The shells from the Andaman Islands are a trifle larger, 

 having a length of 19 millims ; with the exception of this difference, 

 they agree perfectly with the typical shells. In the above-quoted 

 figure of this species the form of the aperture is not at all correctly 

 drawn. The columella has not such a long curve ; and the labrum 

 should be more expanded at basal end. 



26. Nassa (Hima) sistroidea, G. andH. Nevill, Journ. Asiatic 

 Soc. Bengal, 1874, xliii. part 2, pi. 1. fig. 6. 



Hab. "Found in one spot below the rocks near the barracks, Ross 

 Island, very local" (JVilmer). 



In their description of this interesting species, Messrs. Nevill do 

 not remark upon the curious way in which the costae on the body- 

 whorl are trinodose through the prominence of some of the transverse 

 lirse at intervals. The uppermost row of nodulous projections borders 

 the depression or elevation at the top of the whorl ; the median series 

 is situated about the middle, and the lowermost a little below that. 

 This I take to be a specific character, as it is present in all the adult, 

 specimens which I have seen, and the above-named figure of their type 

 also exhibits this peculiarity. The whitish band which is seen within 

 the aperture runs between the uppermost and median series of nodules.
