B. LEEUWINENSIS (E. A. Smith). PI. 3, fig. 49. 



Shell perforate, long-ovate, acuminate above, whitish, more or less 

 streaked and spotted with brownish-corneous. Whorls 5 to 6, a little 

 convex, separated by a rather deep suture, the upper two brownish, 

 minutely punctate, the rest longitudinally wrinkle-striate, ornamented 

 with several transverse series of granules, the last whorl elongated, 

 scarcely granulated below the middle, slightly descending obliquely 

 in front. 



Aperture vertical, inversely auriform, pale brown tinted, scarcely 

 half the entire length of the shell ; peristome white, thin, simple and 

 acute, the hasal margin somewhat effuse ; columellar margin dis- 

 tinctly reflexed, half covering the narrow umbilicus, joined to the lip 

 by a thin callus. Length 27, diam. 12.5, length of aperture 12.5 

 width 6.5 mill. (Smith).

The apical whorls of this and the allied species, B. melo, B. kinyii, 

 and a few others, are punctate, like a fine thimble, and the extreme 

 and rather obtuse apex is introverted, as it were, within the next 

 whorl. The specimens vary somewhat, in length, the dimensions 

 given above being those of an average specimen. B. melo is a 

 broader and more bulky species, anil B. Jdnyii is more acuminate 

 above, less granular, and exhibits more coloration both externally 

 and within the aperture. The umbilicus is more closed than in the 

 present species, and is surrounded by a brown zone (Smith). 



B. IXDL-TUS (Menke). PI. 3, figs. 58, 59, GO, 61. 



Shell perforate, oblong-conic, solid ; color either greenish-yellow, 

 yellowish-olive (nearly uniform or with reddish-brown streaks), or 

 reddish-brown with some lighter streaks; the earlier whorls either 

 white or red-brown, the interior of the umbilicus sometimes red- 

 brown. Surface slightly shining, sculptured with slight growth- 

 wrinkles which are stronger near the suture; the whorls of the spire 

 granulous, by being decussated with spirals, which are wanting or 

 very weak on the last whorl ; spire conic, stout, the apex obtuse, 

 nepionic 1^ whorls finely and densely pitted, the pits somewhat 

 arranged in vertical series, and in places passing into fine vertical
