streaked and variegated with white. Whorls 8, nearly flat, the last 

 angularly compressed at the base, blackish-brown toward the aperture. 

 Aperture oblong-ovate with 5 or 6 folds : a moderate parietal lamella, 

 a stronger one on the columella, a third moderate basal fold, and 

 within the outer lip a fourth fold in addition to one or two smaller 

 ones. Peristome white, narrowly expanded. Length 24, diam. 6^, 

 length of aperture 7, width exclusive of peristome 3, inclusive 5J 

 mill. (Mart.')

" Nearest allied to B. ringens Dkr. and B. punctatissimus Less. 

 In the contour of the shell and form of the aperture, as well as in 

 number of folds, it stands about in the middle between these two 

 species, the narrow peristome approaching that of ringens, the very 

 strong columellar fold that of punctatissimus, while the external 

 sculpture differentiates it from both. Of the folds wnthin the outer 

 lip the strongest stands in the middle of the lip, a weaker one below 

 it, which in the three shells before me, does not extend so far for- 

 ward ; and above the median fold there is a fold in two of the speci- 

 mens. All three are bleached, and the ground-color therefore can- 

 not be described ; but brown streaks like those of B. ringens may 

 still be seen, and also traces of a white marking crossing them, and 

 confined to the wrinkles " (Mart.'). 



I have not seen this species, which from the description must be 

 extremely near 0. fusifonnis Mke., but apparently unlike that shell 

 in the narrow peristome, described as " breviter expansum." 



0. CATHARINE (Pfeiffer). Unfigured. 



Shell shortly rimate, subperforate, fusiform, rather solid, all over 

 lightly punctate-rugulose ; white, with scattered streak-like corneous 

 dots. Spire swollen-turreted, the apex slightly acute. Whorls 8^, 

 a little convex, the last scarcely one-third the total length, having a 

 strong compressed crest with a smaller one behind it ; in front in- 

 terruptedly black-streaked outside and within. Aperture oblique,
