Remarlis. — This species is alhed to Mel. ( Gon) harpa (nobis), but differs in having 

 a larger aperture, and in having more and closer strise. It is also more yellow. In 

 outline it is very nearly the same with granatoides, herein described, but it has not, 

 like that species, any granules, and the two differ in the lower part of the aperture. 

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

Remarlcs. — One of the four specimens before me is more slender than the other 

 three, and may belong to another species. It is of the same honey-yellow color and 

 the stri^ are very much the same. The number of the strise differs, varying from 

 six to eight in the specimens before me, the middle ones being the largest. The 

 aperture is more than one-third the length of the shell.
