Beddome hazards the opinion that the present form is Q. in- ornata, var. l3 of Pfeiffer *. This .statement appears to me to be based on a misconception, for I find a specimen of true inornata occurs in the same box with paTlens. 374. Glessula prestoni, sp. n. Shell cylindro-conoid, rather solid, opaque, a little shining, finely and closely, irregularly costulate-striate, the striae sinuous near the suture, with excessively minute spirals in the interstices ; a shallow groove, bordered by a few irregular spirals below it, runs parallel with and close to the suture from the beginning of.

"Whorls 8, increasing rapidly, flattened, yellowish corneous with fuscous transverse streaks, the last whorl exceedino- f of the entire length of the shell, subangular at the periphery. Aperture nearly vertical, obovate, margins united by a thin callus on the parietal wall; peristome thickened, outer margin slightly * „ Bulimus, 1860, pi. 37, figs. 1, Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Blanford, William Thomas, 1832-1
