130 MITRELLA. 



Described and figured by Reeve as C. lac/ea, Kieiier — 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 Cumingian type specimen. Although 

 revolving strife are neither described nor figured bj^ Reeve, I 

 think it not imi>robable that this will prove to be identical with 

 G. chryaalloidea, Cpr. 



C. NASUTA, Menke. 



Ovately fusiform, smooth, with revolving striae at the base; 

 spire conicall}^ turreted, acuminate ; j-ellowish-white, with supe- 

 rior triangular chestnut-colored maculations and longitudinal 

 flexuous lines ; lip thickened and gibbous in front, 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.
