Pound at Eeal Llejos in Central America in company with 

 C. solida, which it much resembles ; but the apex is longer and the 

 ribs continued to the last whorl. The lower part of the body 

 whorl is spirally striated.

Pound at St. Elena, East Columbia, in eight to ten fathoms of 

 water with a sandy bottom. It is oval, with a rather short can- 

 cellated spire ; the body whorl is grooved, and behind the colu- 

 mella, slightly umbilicated, the upper fold of the columella is 

 duplicate and prominent ; the mouth is interiorly ribbed and the 

 outer lip denticulated at the edge. The colour is dark chesimt

C. testa crassa ovata, ventricosa,, leevi ; spira brevi, acuminata, 

 anfractibus decussatim costatis, sutura distincta ; anfractu ultimo 

 spiraliter obsolete sulcato; apertura subangusta, interne valide 

 costata, prope, marginem costis valide elevatis; columella plicis 

 duabus, postica crassa, duplicata ; labio externo prope suturam et 

 ad canalem emarginato. Colore, pallide fasciatim fulvo. 



Pound at Puerto and in the gulf of Dulce, Central America, in 

 fifteen fathoms of water. It is a ventricose, heavy shell, with a 

 short spire which is decussated, but in the body whorl the spiral 

 grooves are nearly obsolete. The mouth is internally ribbed and 

 the upper fold of the columella is thick and duplicated. It is 

 like C. ovata, but much more ventricose.
