A single specimen of this elegant species was collected from 

 the Gatun of the Banana River. It is a species of the Conus 

 Biirckhardti t3^pe but much larger and when perfect reaching a 

 length of nearly 60 mm. The sculpture is of wide bands formed 

 by deep, and regularly spaced grooves about the lower 3-4ths of 

 the shell.

This is the Covins gaza of Johnson and Pilsbry described 

 from the Miocene of Santo Domingo and the Isthmus. It is a 

 small, pretty species, recognized b}^ its nearl}' biconic outlines 

 and neat sculpture. The spire is high; with nearly smooth, spire- 

 whorls and carinated sutures. The last whorl is rather short and 

 heavil}^ sulcated w^ith about 18, regular, spiral cords, separated 

 b}^ intervals of their own v/idth. 



All our specimens come from Water Ca}^ where the species 

 is fairly abundant. The largest specimen measures 20 by 11 

 mm. Bose's original specimens are from the Miocene of the 

 State of Oaxaca, Mexico. They are somewhat larger, measuring 

 28 by 15 mm.
