of outer lip, as represented on fig. 121b, Conch. Icon. The 

 columella is also more smooth. 



It ranges throughout Polynesia, and extends to the Philippines, 

 but is not reported by M. Deshayes from Bourbon Island, nor 

 have we received it froin any locality so far west. 



Terebra Peasei, Desh. 



1859. Proc. Zool. Soc. London, p. 302. 



1860. T. puncticulata, var., Rve., Conch. Icon., Sp. 99. 



The above species is more nearly allied to Swainsonii, Desh., 

 than \o puncticulata, with which Mr. Reeve has connected it. 

 Puncticulata is more nearly related to affinis, Gray. It was 

 dredged from Honolulu harbor, together with all the species of 

 Terebra described by M. Deshayes from the Hawaiian Islands ; 

 the colors, therefore, cannot be depended on. Swainsonii is a 

 smaller shell than Peasei, and not so slender. The ribs on both 

 species are plicate or angulate, those of Peasei are curved and 

 somewhat roughened, the interstices striate or grooved trans- 

 versely ; those on Swainsonii are straight, smooth, and the inter- 

 stices smooth.

" hybridum, Rve., " " Sp. 21. 



Although we credit Linnaeus as the author of the above spe- 

 cies, Ave are of opinion that he referred to lutea, inhabiting the 

 Mediterranean. 



Cingula, Kien, differs only from the above species in the ar- 

 rangement of its color. It varies in that respect, more than 

 noted by Reeve or Kiener. It is occasionally wholly reddish- 

 brown. We have specimens from all parts of Polynesia and the 

 East Indies. Layardi is added above on the authority of Mr. 

 Reeve. 



TORINIA DEALBATA, Hds.

The above should be compared with S. trochoides, Desh., figured 

 in Jour, de Con. 1858, p. 378.
