46 MR. G. F. ANGAS ON NEW AUSTRALIAN SHELLS. [Jan. 14, 
A very interesting new species, which I have dedicated to the in- 
trepid voyager who, in an open whale-boat, first explored the straits 
that bear his name. 
Triton (EPIDROMUS) BRAZIERI, n.s. (Plate II. fig. 3.) 
Shell elongately turreted, thick, with about twelve rather pro- 
minent rounded varices ; spire very slightly twisted; whorls nine, 
sculptured with regular close-set longitudinal ridges and reticulated 
with irregular impressed stricze; light brown, paler on the varices, 
with a broad slightly darker fascia on the middle of each whorl, and 
a series of small spots at the lower edge of the fascia of the last whorl, 
the fascia darker where it crosses the varices ; columella excavated, 
smooth, orange-coloured ; canal very short, recurved; outer lip orange, 
denticulated within. 
Length 2 in., breadth 73 lin. 
Hab. Lake Macquarie; and Cape Solander, Botany Bay, New 
South Wales. 
Named after its discoverer, Mr. John Brazier, an enthusiastic and 
intelligent conchologist, who has contributed much to our knowledge 
of the Australian mollusca. 
Hexix (TROCHOMORPHA) DEIOPEIA, n. s. (Plate II. fig. 4.) 
Shell deeply umbilicated, depressedly and convexly conical, mode- 
rately thin, finely obliquely irregularly striated, upper whorls brown, 
last whorl black, ornamented with numerous pale diaphanous oblique 
stripe-like spots ; spire convexly depressedly conical, apex obtuse, 
suture narrowly margined ; whorls six, rather convex, the last not 
descending, keeled, somewhat flattened at the base ; umbilicus co- 
nical, moderate, partly surrounded by a faint horn-coloured band 
passing into the interior of the shell; aperture oblique, truncately 
oval; peristome non-continuous, pale horn-colour, margins converging, 
the right thin, slightly expanded, the basal a little thickened, sinuous, 
and somewhat reflexed. 
Diam. maj. 8, min. 7, alt. 43 lines. 
Hab. Marau Sound, Guadaleanar, Solomon Islands. 
This beautiful species is somewhat intermediate between H. me- 
leagris, Pfr., and H. merziana Pfr. Five specimens were obtained 
by my friend Mr. John Brazier, on the trunks of trees, during the 
visit of H.M.S. ‘ Curacgoa’ to Marau Sound. 
Hetrix (CorastA) ROSSITERI, n. s. (Plate II. fig. 5.) 
Shell imperforate, globosely conical, very thin, obliquely irregu- 
larly plicately striated, with the interstices very finely transversely 
striated, pale straw-colour encircled with numerous narrow white 
diaphanous bands, the one nearest the sutures the broadest ; spire 
obtusely conoidal, somewhat flattened at the apex; whorls four, 
convex, the last descending, acutely keeled at the periphery, rounded 
at the base; columellar margin arcuate, narrowly excavated, sharp 
within ; aperture oblique, rhomboidal ; peristome not continuous,
