 Sulphur, p. 41, pi. xii. f. 7, 8. 



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

 acuminata, anfractibus angulatis, longitudinaliter costatis, costis 

 decussatis, ultimi anfractus distantibus, complanatis ; anfractu 

 ultimo antice coarctato, ad columellam umbilicato ; apertura 

 interne leviter costata labio externo antice flexuosa, ad canalem 

 leviter emarginato ; columella biplicata. 



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- 

 nata ; anfractu ultimo, antice subumbUicato : apertura Isevi ; 

 columella triplicata; labio externo ad marginem denticulato. 

 Colore fulvo. 



From Eealejo, 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.

 Conch. lUustr. 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 castaneis. 



This shell, from Van Dieman'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 deHcate buff 

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

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