COLUMBELLA. Ill 



of the species, a form which Sowerby has described us C. pcecila 

 (tigs. 100, 1), from the Philippines. C. spectrur^^Qf^eg. 2), 

 C. nana, Mich. (tig. 3), C. pallida, 

 (tig. 5), and C. lysiska, Duclos (tig. 0), 



C. SOUVERBIEI, Crosse. PI. 40, tig. 8. U ' ^ E R S I T 7" 



Shell ovate, with short spire ; slight^ n< 

 and covered by revolving strife ; white, 

 irregular chocolate spots, forming two broad bands on the body- 

 whorl, and chestnut punctations at the suture; violaceous within 



the aperture. Length, 8'5 mill. 



New Caledonia. 



Closely allied to C. variant, but differing in being less tuber' 

 ciliated, in coloring, in the absence of the dark basal spot, etc. 



C. miLiA, Duclos. PL 40, tig. 7. 



Shell thick, ovate, round-shouldered, with obsolete revolving 

 ribs ; white, with zigzag chestnut markings. Length, '1 inch. 



Habitat unknown. 



Figured and named, but not described ; I am unable to 

 identity it. 



C. PALLIOA, Philippi. 



Shell oblong-fusiform, with revolving stria 1 ; white, with a single 

 chestnut bund, composed of maculations ; aperture violaceous 

 within. Length, '5 inch. 



Mazatlan. 



This species, described twenty-live years ago, but never figured, 

 remains unrecognized. Carpenter, who so thoroughly studied 

 the mollusca of Mazatlan, and of the West Coast of North 

 America, could make nothing of it. Philippi compares it with 

 C. azora, Duclos, which, he says, it resembles in form but differs 

 in being one- instead of three-banded. 



C. SCAIJ'TA, Reeve. PI. 40, lig. <). 



Shell ovate, transparent golden yellow, marked transversely 

 with sharply angular pale lines; spire short; whorls longitudi- 

 nally plicately ribbed; aperture small, oblong, sinuous; lip 

 thickened, notched at the upper part, denticulated within. 



Length, '25 inch. 



Habitat unknown.
