RemarTcs. — This is a pretty little species, usually with four well-marked, rather 

 broad brown bands. In one of the six specimens before me there are only three in- 

 distinct bands. It is closely allied to Melania ( Goniohasis) cognafa, Anth., and near 

 to Georgiana (nobis) . It differs from cognata in being more drawn out in the spire 

 and having less inflation of the body whorl. The aperture is about one-half the 

 length of the shell.

Remarlcs. — A number of specimens were sent to me by Mr. Miles, all from the 

 same habitat. It is nearly allied to Melania [Goniohasis) Niagarensis, (nobis,) but 

 may be distinguished by its being less fusiform, being thinner and usually of a 

 darker green. The aperture is about six-fifteenths the length of the shell. I name
