S. HECTOR Pfeiffer. Unfigured. 



Shell subimperforate, elongate-ovate, rather solid, tawny-white 

 under a deciduous cuticle ; spire conic, the apex rounded ; whorls 6, 

 slightly convex, the earlier closely hair-striate, the last scarcely ex- 

 ceeding the spire in length, plicate-striate and obsoletely decussated. 

 Columella slightly arcuate, not folded. Aperture subvertical, 

 acuminate-oval, white inside, shining ; peristome white, margins 

 joined by a white callus, the right margin somewhat thickened, very 

 narrowly expanded; columellar margin dilated above, adnate. 

 Length 71, diam. 35 mill.; aperture, length 36, width 19? mill.

Has been considered a Borus of the B. oblongus group, on account 

 of the color and the sculpture of earlier whorls, but is evidently 

 much slenderer than any of that group. 



S. LARGILLIERTI Philippi. PI. 26, figs. 89, 90. 



Shell elongate-oblong, the apex obtuse, rather thin, tawny, painted 

 with irregular chestnut streaks. Whorls 6j, a little convex, under 

 a lens seen to be obsoletely transversely striated ; the last whorl 

 two-fifths the total length ; suture hardly marginated, slightly cren- 

 ulated. Aperture oblong-ovate ; columella white, somewhat twisted ; 

 lip white, simple. Alt. 53 diam. 21 mill. (Phil.}.

The present Bulimus shows great agreement in structure with B. 

 taunaisii of which I have a variety with exactly the same coloring ; 

 but it is far smaller, conspicuously thinner-shelled, the last whorl 

 narrower, the contour more cylindrical, less conical, the white fold 

 of the columella less projecting, and the sutures of the last whorl 

 are not margined differences justifying the separation from B. 

 taunaisii (Phil.'}.
