92 DescrijJtions of New Fluviatile Shells. 



fescens is described as having eight. A few of the specimens 

 are irregularly and strongly striate on the body whorl. 



10. Melania brumica. 



Plate II. Fig. 10. 



T. conico-ovata, glabra, tenui, fusco-virente ; spira obtuse elevata ; 

 anfr. 6, superioribus, subplanis, ultimo convexo, interdum trifasciato ; 

 suturis impressis ; apertura magna, ovata, intus albido-rubescente ; 

 columella incurva, sinum vix formante. 



Shell elongate-ovate, smooth, thin, brown ; spire obtusely 

 elevated ; whorls six, nearly fiat ; body whorl convex, some- 

 times three-banded ; sutures irregularly but decidedly im- 

 pressed ; aperture large, broad-elliptical, within whitish, or 

 tinted with reddish ; columella somewhat indented below the 

 middle, and forming a very small sinus at base. 



Length 0.76 inch (20 millim.). Diam. 0.32 inch (8 millim.) 



Length of aperture 0.37 inch (9 millim.). 



Breadth of do. 0.23 inch (6 millim.).

Obs. — A smooth, fine species with no very prominent cha- 

 racters. May be compared with M. perfusca Lea, but is less 

 cylindrical, and much less ponderous ; the whorls are also more 

 convex, and the sutures more distinctly impressed ; it is alto- 

 gether a broader and thinner shell. Some specimens are finely 

 banded, the lower band being often concealed partially by the 

 revolutions of the succeeding whorl. The body whorl has 

 three bands in the variety, and these also appear within the 

 aperture. All the specimens before me, some fifty in number, 

 are more or less decollate, and only two or three arc banded.
