Descriptions of New Flumatile Shells. 



tinct, narrow bands are often visible on the shell ; a very neat 

 and graceful species. 



25. Jflelania imbricata. 



Plate III. Fig. 6. 



T. conica, glabra, subcrassa, cornea ; spira elevata ; anfr. 8-9, supe- 

 rioribus planis, utrinque angulatis, ultimo subconvexo, indistincte bi- 

 angulato ; suturis valde impressis ; apertura elongato-ovata, intus albida, 

 columella incurva, in sinum tenuem producta. 



Shell conical, nearly smooth, rather thick, light horn-colored ; 

 srjire elevated, but not acutely so ; whorls 8-9, flat ; lines of 

 growth distinct, having almost the appearance of ribs; two 

 lines, distant, slightly visible, surround each whorl, and from 

 these the whorls incline towards each other to form a broad 

 groove between them ; sutures well impressed ; aperture, small, 

 narrow ovate, within whitish ; columella much indented and 

 curved, forming a slight sinus at base. 



Length 0.88 inch (23 millim.). Diam. 0.30 inch (8 millim.). 



Length of aperture 0.33 inch (8 millim.). 



Breadth of do. 0.21 inch (5 millim.). 



Habitat. Alabama.

Obs. A fine symmetrical shell, some of its varieties ap- 

 proaching M. sordida Lea in form, but differing in every other 

 respect. The whorls enlarge regularly, and the lower raised 

 line on the whorls being consequently more prominent, the 

 spire has somewhat an imbricated appearance, giving rise to its 

 specific name. The specimens before me, twelve in number, 

 are all decollate. 



The upper whorls are often rather prominently ribbed, and 

 the concentric lines thereby rendered crenulous.
