examination of the specimens from whence Mr. Hanley’s 
descriptions were taken, have thrown considerable light 
upon the subject. We have thought it better to erase the 
descriptions at page 172 and give the following derived 
from the shells themselves, which not having seen, we had 
contented ourselves with copying from Fleming. 
O. UnipentaTa, fF. p. 310.—not Macg. p. 154.— 
Turzso U. Mont. p. 324.—Turt. D. p. 222. Oblong- 
conical, solid ; whitish, moderately glossy, smooth ; whorls 
5 or 6, not much raised; aperture one third of the entire 
length, not at all effuse at the base; outer lip ovate, 
striated internally with fine raised spiral lines ; the tooth- 
like plate horizontal, placed a little higher up than the 
middle of the pillar lip; apex blunt. Length full one 
quarter of an inch, breadth rather more than half the 
length. 
O. Pricata. Fl. p. 310. (not Macg.)—Turbo P. | 
Mont. p. 325?—Turt. Dic. p. 222. Closely resembling 
the last, but although much smaller, the whorls are 
always as numerous, and often more so(7). The shell 
too is narrower in proportion to its length, and the 
whorls are flat and polished.
