LITHASIA. 35 



shoulder; suture impressed; aperture irregularly ovate ; outer lip 

 waved ; inside of the aperture whitish or brownish, often with ob- 

 scure bands ; columella rounded, extending into abroad, shallow sinus. 



Habitat. — Nolin TJiver, Kentucky. 



Diameter, -38 (10 millim.') ; length, -GG inch (17 millim.) Length of 

 aperture, -35 inch (9 millim.). Breadth of aperture, -19 inch (5 

 millim.). 



Observations. — A somewhat vai'iable species ; the remarkably shoul- 

 dered body-whorl will, liowever, readily distinguish it; diflcrs from 

 31. obovata, Say, by its more distinct spire, its greater proportionate 

 breadth, and bj' the form of the aperture ; it is also much less ponder- 

 ous ; many specimens are obscurely banded on the body-whorl ; this is 

 more distinctly visible in the young shell. — Anthony. 



The .shell figured and described by Mr. Reeve as rarinodosa 

 is evidently the same as the above. The description 'is 



Mclania rarinodosa. — Shell ovately turbinated, olive, obscurely 

 broad-banded; whorls 5-G, flatly convex, obtusely swollen Fig. 77. 

 and obsoletely noduled round the upper part; aperture 

 ovate ; columella twistedly effused. 

 Habitat. — United States. 



Anthou}', Manuscript in Mus. Von dem Busch. 



Observations.— Jiiithcr a doubtful species, received by Dr. 



Busch from Mr. Anthony with the above name in manuscript. — lieeve. 



Melania consanguinea. — Shell ovate, smooth, thick, brownish-olive; 



spire short, acuminate; whorls eight, the upper ones nearly flat, the 



last two or three much shouldered ; body- whorl very large, slightlj- 



constricted in its upper portion, and very faintly banded; 



'^ ■ sutures deeply impressed ; aperture regularly ovate, within 



livid, approaching to purple far within; columella rounded, 



with scarcely a perceptible sinus, tinged with purple at base. 



Habitat. — Indiana. 



Diameter, -40 inch (10 millim.); length, -75 inch (20 mil- 

 lim.). Length of aperture, -40 inch (10 millim.) ; breadth of aper- 

 ture, -20 inch (Jt millim.). 



Observations. — Allied to, but perfectly distinct from, 3f. xindosa ; its 

 greater solidity, more elongated spire, and greater number of whorls 

 will at once distinguish it- the whorls of the spire arc much more 

 convex, and there is no prominent angle formed by the shoulder on 

 the body-whorl as in M. undosa. — Anthony.
