Shell elongate, rimate ; white, yellowish at the apex and around 

 the base ; spire acuminate ; whorls 5 to 6, the upper two embryonic 

 whorls punctate-reticulate, a little convex, the restless convex, sepa- 

 rated by slightly oblique sutures, edged below the suture by a very 

 narrow opaque white line ; sculptured with very delicate oblique 

 growth-lines and somewhat waved, extremely fine spiral lines ; last 

 whorl elongated. Aperture reversed ear-shaped, exceeding half the 

 total altitude of the shell ; outer lip thin, a little expanded anteriorly ; 

 columella thin, reflexed over the narrow perforation. Alt. 21^, 

 diarn. 9^, length of aperture 12, width 6^ mill. (Smith.)

Bulimulus (Drymceus) mossi SMITH, Journ. of Conch, viii, no. 8, 

 p. 243, pi. 8, f. 8 (Oct. 1, 1896). 



In color this species resembles B. Rawsoni of H. Adams. It differs 

 from that species, however, in form, the more effuse outer lip, and 

 the more narrowly reflexed columella. In B. Rawsoni the spire is 

 longer and the aperture shorter than in this species, and the relative 

 proportions are quite different. The single specimen examined has 

 been kindly submitted to me for examination by Mr. W. Moss, after 

 whom I have the pleasure of naming the species. (Smith.) 



D. BINOMINIS (Smith). PI. 12, fig. 9. 



Shell subperforate, somewhat thin, oblong-conic, rather ventricose, 

 pale reddish-brown or inclining to yellowish-white. Whorls 6, grad- 

 ually increasing, the last somewhat ventricose, equal to two-thirds of 

 the length of the shell. Spire conic, sharp. Aperture oblong-oval ; 

 peristome acute, not expanded ; columellar margin reflexed over the 

 narrow umbilicus. Dimensions of a typical example, alt. 23, diam. 

 12, length of aperture 11, width 6 mill. (Guppy.) 



Island of Grenada, shady places, 500-1500 feet alt., on trees ; 

 rather rare (H. H. Smith).
