is purplish. The aperture is more than half the length of the shell. 1 dedicate this 

 species to my friend, W. S. Vaux, Esquire, who has done so much to promote the 

 objects of our Academy.

Remarks. — Two specimens were received among Mr. White's shells, but the part of 

 Georgia was not designated, from where he obtained them, probably towards the 

 North. In outline it closely resembles Nickliniana, as well as Vaaxiana, herein des- 

 cribed. It is rather more obtuse in the apex than Nickliniana, and not so round at 

 the base, and it has bands which the other has not. Both the specimens are furnished 

 with three equidistant brown bands, obscure outside, but well defined inside. The 

 older of these two has a thickening inside of the outer lip, and the bands do not ex- 

 tend to the margin. The aperture is more than the half the length of the shell. I 

 dedicate this species to the Rev. George White, who has done much to elucidate a 

 knowledge of the Mollusca of his State.
