Shell ovate, subrimate, rather thin. Whorls 5, slightly convex, 

 rapidly increasing, the last three-fifths the entire length ; longitudi-

 11, f. 1,2. 



Allied to B. blainvilleanus Pfr., but with different sculpture and 

 lacking the columellar fold ; the color darker, with irregular spots 

 and streaks, and without lightning lines. 



P. APPUNI Dunker. PI. 31, figs. 34, 35. 



Shell ovate-acuminate, narrowly umbilicated, rather solid, irreg- 

 ularly longitudinally striated, roughened, as if malleated all over ; 

 unequally plicate below the suture. Unicolored pale brown, cov- 

 ered with a brownish-corneous or greenish epidermis. Whorls 5, 

 convex, separated by a rather deep suture ; the last whorl some- 

 what swollen, about three times longer than the spire ; columella 

 slightly folded, a little receding. Aperture ovate, slightly oblique ; 

 peristome thickened, expanded, more or less reflexed, brownish- 

 orange. Length 60-65, diam. 34-36 ; aperture, alt. 34-35, width 

 18 mill. (Dkr.).

This snail belongs to the group Dryptus Alb., and is nearest allied 

 to B. blainvilleanus Pfr., though its general aspect reminds one of 

 small varieties ofB. moritzianus. It seems to vary in form judging 

 by the two well preserved specimens before me, the shorter one by 

 5 mill, is 2 mill, wider than the longer shell. (Dkr.).
