Remarks. — This species is very near in outline and size to Coosaerms, herein des- 

 cribed. It differs in being without bands, except obscure ones on the upper whorls, 

 and in having but few raised striae. The channel at the base also differs in ellipsoides 

 being slightly retuse. The color and whole aspect of the two specimens before me are 

 exactly alike, having a peculiar greenish yellow epidermis. In both these specimens 

 there are two raised cord-like strice above and a few impressed strice at the base.

Remarlcs. — -There are five specimens before me, two of them being old and so much 

 eroded as to leave little more than the body whorl. The other specimens are more 

 perfect, but the apices are worn and their character unascertained. The species is 

 allied to Melania (Goniobasis) Hmjsiana (nobis), but may be distinguished by its not 

 being cylindrical and by the aperture being longer. Like Ilaysiana, the stria) are 

 coarse and rounded, somewhat cord-like. These stria; number eight to ten. As 

 Haysiana is sometimes found without strise, this species may also be found without 

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