longitudinally finely striated and marked with fine microscopic spiral 
strie. Colour chocolate-brown, mottled with darker, and freckled 
and blotched with white. 
HAMINEA GALBA. 
Shell oval, light, shining, yellowish; marked with longitudinal 
lines of growth, and finely microscopically spirally striated ; outer lip 
nearly straight, and very slightly produced posteriorly ; inner lip 
thickened somewhat at the base, and slightly reflected ; columella 
strongly arched at lower part. 
The shell of this species can hardly be distinguished from that of 
H. crocata (nob.); but the animal differs widely ; its description was 
given, by mistake, as that of H. crocata, and may be found on page 
20 of ¢ Proc. Zool. Soc.’ for 1860. 
The description of the animal of H. crocata we give below :— 
HamINeEA Crocata (nob.). 
Animal.—Cephalic disk square, oblong, in advance of the shell, 
slightly notched at the centre of the front side, at the posterior side 
provided with a pair of flat, rather broad, recumbent lobes, which are 
rounded at their extremities; lateral lobes reflected on the sides of 
the shell two-thirds of its length; foot extending beyond the shell 
posteriorly, and rounded at its termination. Colour cinereous; 
pellucid. 
CERITHIUM GRACILE. 
Shell light, thin, turreted, slender; whorls convexly rounded, 
ribbed longitudinally and varicose, ribs rounded and becoming obso- 
lete on the last whorl, ornamented with spiral raised strize or ribs which 
are somewhat flexuous and alternately smaller ; aperture oval ; outer 
lip somewhat expanded ; columella arcuate and callous, callosity join- 
ing the outer lip posteriorly ; canal short, slightly recurved. Colour 
white or light-fawn, irregularly marked with brown. 
CERITHIUM UNILINEATUM.

varicose, spirally finely ribbed ; aperture ovate. Coiour white, spotted 
with brown, spots arranged spirally ; a band of dark purple encircling 
the whorls, at their upper margin. 
CERITHIUM FUCATUM. 
Shell light, thin, vitreous, pyramidal ; whorls seven or eight, slightly 
convex, ornamented with three equal rows of granules, and the in- 
terstices with a single ridge and fine microscopic strice, granules be- 
coming obsolete on Jast whorl; last whorl ribbed and longitudinally 
striated, striee fine, microscopic; aperture oval; outer lip slightly
