136 MITRELLA. 



Described and figured by Reeve as C. lacfea, Kiener which 

 is a very different species, originally figured by Duclos ; I am 

 therefore compelled to change the name, and call it after the 

 gentleman who collected the Cumingiantype specimen. Although 

 revolving striae are neither described nor figured by Reeve, I 

 think it not improbable that this will prove to be identical with 

 C. chrysalloidea, Cpr. 



C. NASUTA, Menke. 



Ovately fusiform, smooth, with revolving strife at the base;^ 

 spire conically tnrreted, acuminate ; yellowish-white, with supe- 

 rior triangular chestnut-colored maculations and longitudinal 

 flexuous lines ; lip thickened and gibbous in fron^, denticulate 



within. L. 9'8 lin., apert. 5'5 lin., lat. 4 lin. 



Mazatlan. 



An unfigured species, which has not been recognized by Car- 

 penter or subsequent students. 



C. MARQUESANA, Gaskoin, PI. 50, figs. 44-47. 



Earlier whorls very faintly minutely costate, balance smooth, 



shining, last one with revolving striae at base; yellowish white, 



encircled with narrow chestnut lines or sometimes irregularly 



maculated with chestnut, tip of spire rosaceous. Length, 10 mill. 



Polynesia, Viti Is., Paumotus, Borneo, Loo Choo, 



Hong Kong, New Caledonia. 



Very variable in coloring, which has occasioned a number of 

 synonyms. These are C. tteniata, Ads. and Reeve, not Phil, 

 (fig. 46) ; C.lineolata and decolor, Gould (unfigured), referred 

 here by Carpenter after an examination of the types; C.flammea, 

 Pease (unfigured) ; C. sublsevis, Montr, (fig. 41). 



C. BICINCTA, Gould. 



Shell ovate, sniall, turreted, thin, smooth, ash-color with two 

 fulvous bands ; whorls eight, slightly convex, suture impressed ;
