resemblance to Bridgesiaua (nobis), but may be distinguished by its longer spire, its 

 darker color and being less fusiform. The color of the interior also differs, the 

 Murrayensis being of a yellowish tint. The aperture is rather more than one-third 

 the length of the shell.

Remarhs. — This species is nearly the same in outline with granata (nobis), but 

 differs in being a larger species, more horn colored and being without bands. In the 

 aperture it is wider at the base, the fuse being larger. Like Tryoniana (nobis), it 

 has numerous though not so many granules, and it differs in the aperture. The 

 young specimens have well formed folds on the upper whorls. The aperture is about 

 one-half the length of the shell.
