Remarlcs. — This is a regular fusiform species, with an agreeable outline near to 

 that of gracilior, herein described. It is not so stout a shell and is rather smaller, 

 and having bands cannot be easily confounded with that species. The aperture is 

 more than half the length of the shell, and the apex is quite pointed.

Remarks. — Two specimens of this pale little species are before me. They are 

 nearly allied to punicea, herein described, but it is a shorter and thinner species and of 

 quite different color in the epidermis. The aperture is more elongate and larger 

 in proportion. Both specimens are decollate, but in one there are four whorls 

 apparent, and I presume the normal number would be six. The larger specimen 

 has an obscure band on the upper part of the whorl, which is well defined inside. 

 The smaller one has none whatever. There is a slight disposition to take on folds 

 on the upper whorls. The aperture is about one-half the length of the shell.
