414 MESSES. MELVILL AND STANDEN ON [June 18, 



Nassa (Hima) ischna Melv. 



P.G-. Gulf of Oman, near Maskat. 



M.C. Charbar, and elsewhere along the coast of Baluchistan, 

 not infrequent. There appear to be two varieties : one plain, uui- 

 colorous, the other banded with chestnut conspicuously below the 

 sutures. "We have noticed specimens, occasionally, varicose, as is 

 the case with iV. pygrrKea, Ph. 



Nassa (Hima) mamilliebea Melv. 



P.G. 7 to 25 fathoms, mud. At Linjah, 3| to 5 fathoms. 

 At Hindarabi I. a pure white variety, which might be designated 

 var. hindaraUca, occurs at 25-50 fathoms, mud. In sculpture and 

 all other details it is identical with the typical form. 



M.C. Charbar. 



I. Karachi. 4 fathoms. 



This was considered a Niotha at first, but it seems better placed 

 here. Many of the Adamsian subdivisions of this genus run into 

 each other ; and such is the variation in many of the Nassai, that 

 individuals occur which possess, blended in themselves, certain 

 qualifications of two, or even three, of the subgenera. We have 

 emended the spelling of the specific name, ' mammillifera ' being 

 unclassical. 



Nassa (Hima) paupeea Gould. 



P.G. Gulf of Oman : Maskat, 15 fathoms. Also lat. 24° 55' N., 

 long. 57° 59' E. ; 37 fathoms, mud and sand. 



M.C. Charbar. 7 fathoms, rock. 



Identical with N. plebecula Gould, a very variable species. Some 

 of our examples are wholly pale stramineous, others are adorned 

 with a dorsal chestnut taenia across the base of the body-whorl. 

 Tryon (Man. Conch, iv. p. 47) may be right in uniting many so- 

 called species under this head. 



Nassa (Hima) pseudoconcinna Sm. 



P.S. Gulf of Oman, rare. Lat. 27° N., long. 52° E. ; on tele- 

 graph-cable, 54 fathoms. 



I. Karachi. Bombay (F. W. T.). 



Nassa (Hima) stolata Gmel. (=ornata Kien.). 



P.G. No special locality. 



I. Bombay (F. W. T. and Abercronibie), amongst loose rocks 

 at low tide. Common southwards (Lt.-Col. H. D. Olivier). 

 "We have this also from Calcutta {Lady Herschel). 



Nassa vaeians Dkr. 



P.G. Telegraph-cable, amongst shell-growth ; 40 to 50 fathoms, 

 mud. Lat. 27° N., long. 52° E. 



Ctllenb fuscata H. Ad. 

 M.C. Charbar Bay. On sand, 4-8 fathoms. 

 I. Bombay, abundant (Abercrombie).
