COLUMBELLA. Ill 



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

 (figs. 100, 1), from the Philippines. C. spectrum, Reeve (fig. 2), 

 C. nonn Mich. (tig-. 3), C. pallida, Desh., C. daliola, Duclos 

 (tig. 5). and r. Itjsixh-u, Duclos (fig. (>), are synonyms.

. Shell ovate. with short spire ; slightl}' nodulous on the shoulder, 

 Miid covered by revolving stria 1 ; white, maculated with large

Shell oblong-fusiform, with revolving striae ; white, with a single 

 chestnut band, composed of maculations ; Mperture violaceous 



within. Length, '5 inch. 



Mazatlan. 



This species, described twenty-five yi:i rs ago, but never figured, 

 remains unrecognized. Carpenter, who so thoroughly studied 

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

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

 C. azora, Duclos, which, he sa} r s, it resembles in form but differs 

 in being one- instead of three-banded.

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

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