Shell narrowly umbilicate, depressed, subcarinate, yellowish chestnut, 

 paler and dull yellow below around the umbilicus, surrounded by a narrow 

 pale band, which is only well marked near the mouth ; the sculpture is fine 

 and subgranulate, formed by decussating strise of growth and fine sjDiral 

 lines, the latter disappearing below near the umbilicus. Spire depressedly 

 convex, apex obtuse ; suture linear, and not impressed, except in the ante- 

 rior half of the last whorl. Whorls 4^, all except the last fiat, gradually 

 increasing ; the last whorl more convex above, especially towards the mouth, 

 where it is slightly broader, subangulate at the periphery, convex below, 

 but a little compressed close to the mouth. Aperture oblique, broader than 

 high. Innately semioval, subangulate at the upper portion of the outer edge, 

 pale livid within, with the narrow whitish band along the blunt keel very 

 conspicuous. The peristome is not tliickened, except very slightly along 

 the basal margin, which is white, oblique, and straigkt for a considerable 

 distance, being very slightly reflected at the umbilicus; the other margins 

 are regularly convex, tlie upper and lower margins being subparallel ; the 

 callus connecting the free margins of the aperture is thin, but granular. 

 Major diameter 1'72 inches, minor 1'4, axis O'S ; aperture 95 inch broad, 

 Q-GS high (measured obliquely). 



Col. Beddome has sent to me two specimens of this shell, one adult, 

 the other not quite fully grown. The species is near S. tinostoma, but is 

 considerably smaller, and the peculiar flattening and compression of the 

 last whorl, near the mouth, is far less, the aperture being, in consequence, 

 not nearly so broad in proportion to the height. Another allied form, also
