Diam - ' 27 -- Length -53 inch. 



Remarks. — A single specimen was among a number of Melauidce kindly given to me 

 by Mr. Sellers a long time since, one of which I then named after him. This pretty 

 little species is ornamented with regular folds, which are slightly curved, and incline 

 to the right. These folds cease at the middle of the body whorl, being cut by an in- 

 dented line below the suture, causing a granulation. In this specimen are five bands 

 which are indistinct. It has nearly the same outline as crispa, herein described, but 

 it is smaller, is not clathrate above, and the folds are not so strong. The aperture is 

 about half the length of the shell.

 ct valde impressis; anfractibus iustar quinis, convexiuseulis ; apertura grandi, rhomboidca, albida- 

 labro acuto, vix sinuoso ; columella ineurva et contorta. 



Shell folded, fusiform, rather thick, olivaceous, shining, without bands ; spire ob- 

 tusely conical; sutures irregularly and very much impressed; whorls about live, 

 somewhat convex ; aperture large, rhomboidal, whitish; outer lip acute, scarcely sin- 

 uous ; columella bent in and twisted.

 Diam. -31, Length -60 inch. 



Remarks. — I have two specimens before me varying little but in size. It is a well 

 characterized species, having folds, more or less distinct on all the whorls. These folds 

 are rather close, and incline to the left. In one of the specimens there are two lines 

 which cut the folds immediately under the suture. In outline it is near to omatella 

 herein describd, but it cannot be confounded with that species, which is of a different 

 color and is banded. The aperture is nearly the half of the length of the shell.
