246 LAND AND FRESH-WATER SHELLS OF N. A. [pART IV. 



obtusely elevated, cousistiiig of 5-G convex whorls ; color brownisli- 

 3'ellow, with thi-ee dark brown bands about the middle of the body- 

 whorl, and one very obscure one at the suture ; suture deeply 

 impressed ; apei'ture broad, ovate, not large, exhibiting the bands 

 inside ; columella deeply rounded, indented and callous ; sinus none. 

 Habitat. — Tennessee. 



Observations. — A short, pretty species with no very marked char- 

 q,cters, though easily recognized as distinct on examination ; in form 

 _ and coloring somewhat like M. compacta (nobis), but far less 

 solid and heavy than that species ; the spire is more ele- 

 vated and acute and the surface smooth. It most nearly 

 resembles, perhaps, 31. coronilla (nobis), but is less elevated 

 and has not the peculiar crowning i-ibs of that species, which is suf- 

 ficient at once to distinguish it. It is also more robust. — Anthony. 



Figured from Mr, Anthonj^'s type specimen. Mucli more 

 inflated and shorter tlian G. Georgiana, Lea. It also differs 

 from that species in possessing two bands onl3\

Description. — Shell smooth, fusiform, inflated, rather thick, yellow- 

 ish, bright, banded; spire very obtuse; sutures impressed; whorls 

 five, convex; aperture large, subrhomboidal, whitish and banded 

 within; outer lip acute, straight; columella bent in, thickened and 

 somewhat twisted. 



Operculum subovate, dark brown, with the polar point near to the 

 base on the left margin. 



Habitat. — Noi'th Georgia. 



Diameter, -20; length, -57 of an inch. 



Observations.— Among a number of ^Manilla; from the Smithsonian 

 Institution, were two small specimens which have the same outline 

 and same form of aperture, but which differ much in color, rig. 480. 

 That which is described above seems to me to be the normal Mi 

 character and will serve as the type. This has three well ^SL. 

 defined bands, the middle one of which is the broadest, and ^^ 

 it has a character which I have not seen in any of our 3Ielanid(B, that 

 is, longitudinal, whitish raaculations, which are dispersed over the
