fluent, dark rufous bands ; spire as long, or rather longer than 

 the aperture, with three or four widely interrupted bauds ; suture 

 not very deeply impressed ; whorls a little convex ; labrum widely 

 curved a little outwards ; columella rather wide at its origin. 



Length one and a half inch ; greatest breadth, excepting the 

 lip, (parallel, of course, to the suture,) seven-tenths of an inch. I 

 obtained it on the side of the road between Vera Cruz and Mexico. 



B. EMEUS. — With crowded, minute, transverse striae. Inhabits 

 Mexico. Shell conic or elongate ovate, slightly angulated on the 

 middle of the volutions, and covered with minute, undulated, 

 impressed, capillary lines ; whitish, with maculated bands : suture 

 not deeply impressed : aperture shorter than the spire ; labrum 

 exteriorly simple, interiorly with a thickened submargin ; colum- 

 ella short, recurved ; umbilicus small, but distinct ; spire with 

 the angulation concealed by the suture ; body whorl with the 

 angulation almost obsolete. 



Length thirteen-twentieths of an inch ; greatest breadtb 

 (parallel to the suture) three-tenths. I found this species on the 

 road from Vera Cruz to Mexico. As I possess only the " Tableaux 

 Systematiques" of Ferussac's splendid work, the preceding species- 

 of Bulimus are offered with considerable hesitation ; but those 

 who possess that work can readily detect an error, if there be one. 



Note. — Through the kindness of Dr. Meigs, the obliging 

 Librarian of the Academy, I have been able to hare impressions 

 taken of Mr. Say's plate of Helix clausa.
