 Popelair's Bulimus. Shell ovate, extremely ventricose, 

 rather thick, somewhat compressed, whorls swollen, 

 crenulated round the upper pai't, concentrically 

 somewhat distantly ridged and minutely granulated 

 towards the apes ; columella arched, callous at the 

 upper part with age, lip thickened, reflected ; light 

 chesnut-brown, covered with a thick brown epidermis, 

 which is sometimes peculiarly dissolved, as it were, 

 in longitudinal zigzag streaks ; aperture livid, lip 

 white.

This fine zigzag-marked species, distinguished under 

 the above names by Pfeiffer and Valenciennes, is, without 

 doubt, the same described by M. Nyst in the Transactions 

 of the Eoyal Academy of Brussels in honour of the Baron 

 de Popelair. Mr. Cuming possesses a specimen, bke 

 M. Nyst's, quite destitute of the zigzag marking, which is 

 not a distribution of colour, nor the result of a double- 

 memln-ane arrangement of the epidermis, as in the Phi- 

 lippine species ; it has rather the appearance of being 

 partially dissolved, as though it were occasioned by the 

 percolation of some solvent out of the sutm-es, though in- 

 capaljle of such an explanation.

The chosen Bulimus. Shell elongately oblong, some- 

 what fusiform, umbilicatcd, whorls rather convex, 

 concave round the upper part, very closely flatly 

 granulated throughout, granules in transverse rows, at 

 rather distant intervals, larger, last whorl angularly 

 compressed at the base; aperture oblong-oval, an- 

 gulated and channelled at the base. Up sUghtly 

 expanded and reflected, margins joined by a narrow 

 callous ridge; chesnut-brown, flamed with yellow, 

 bp deep rose.

I much doubt whether this is anything more than a 

 variety of the B. goniostoma. I have not met with it in a 

 state intermediate between the specimens here represented, 

 but it is certain that the sculpture oiB. egregius is precisely 

 that of B. goniostoma in an exaggerated and more luxu- 

 riant condition, whOst the species are abke in form.

 transverse rows at rather distant intervals a little 

 larger, last whorl compressed at the base ; aperture

Quite an isolated form of the geiuis, few species pre- 

 senting much approximation to this in respect of its 

 angular oblong channelled aperture, besides the precedino' 

 and one or two of smaller size, to be described hereafter, 

 from the Province of Mcrida, New Granada.
