C. testa subcykndrica, laevigata, epidermide fusca induta ; spira 

 acuminata, aufractibus angulatis, longitudinaliter costatis, costis 

 decussatis, ultimi anfractus distantibus, complanatis ; aufractu 

 ultimo antice coarctato, ad columellam umbikcato ; apertura

This shell was procured in the gulf of Papagayo and at San 

 Bias, in seven to fourteen fathoms water, it is of an oval form, 

 with the last whorl subcylindrical ; the spire is acuminated, con- 

 sisting of angular whorls which are decussated and ribbed. The 

 body whorl is rather contracted anteriorly and umbilicated near 

 the anterior termination of the columella. The ribs on the body 

 whorl are distant, broad, and flat.

C. testa ovali, cancellata,, ventricosa ; spira subelongata, acumi-

Prom Realejo, on the W. coast of America. Something like 

 C. Candida, but of a brown colour, with a more acuminated spire, 

 the whorls of which are less rounded ; and the mouth is smooth. 



.15. Cancellaria granosa (pi. xcv. f. 58, 59.), Sowed//, 

 Conch. Illustr. No. 15. fig. 17. (f. 16, exclusa.) 



C. testa, ovali, costis noduliferis granulata ; spira, acuminata ; 

 anfractibus angulatis, angulo prominente granoso : apertura intus 

 leviter costata ; columella granulata, obtusa. triplicata. Colore 

 pallide fulvo-rufescente, ad angulum anfractuum maculis castaueis. 



This shell, from Van Dieinan's Land, is distinguished by the 

 spiral ribs forming a series of tubercles in passing over the longi- 

 tudinal ribs, which are still more strongly tubercled at the angle 

 of the whorls. The columella is granulated and its folds small ; 

 the mouth is lightly ribbed within. The shell is of a delicate buff 

 colour with chesnut spots on the angle of the whorls, and the 

 mouth pale fawn. We separate the shell represented in Conch.
