fluent, dark rufous bands ; spire as long, or rather longer than 
the aperture, with three or four widely interrupted bands ; 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 strise. 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 
ano’ulation almost obsolete. 
Leno;th thirteen-twentieths of an inch ; cTeatest breadth 
(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 I3r. Meigs, the obliging 
Librarian of the Academy, I have been able to have impressions 
taken of Mr. Say’s plate of Helix clausa.
