624 MR, G. F. ANGAS ON NEW SPECIES OF HELICID&. [Dec. 9, 
4. Descriptions of Eight New Species of Helicide from the 
Western Pacific Islands. By Grorcr Frencu Anaas, 
C.M.Z.S., F.L.8., F.R.G.S., &e. 
(Plate XLVIII.) 
Heurix (CorastA) psycue, n. sp. (Plate XLVIII. fig. 1.) 
Shell imperforate, depressed, thin, obliquely irregularly plicately 
striated, pellucid, white, covered with a yellowish-brown shining 
epidermis; spire scarcely elevated, obtuse at the apex; whorls 3, 
flatly convex, margined at the sutures, the last not descending, pro- 
minently keeled at the periphery, flattened above and ventricose 
below ; columellar margin arcuately descending, narrowly excavated, 
sharp within ; aperture large, oblique, subovate ; peristome not con- 
tinuous, white, slightly reflected, the upper margin nearly straight, 
not flexuous. 
Diam. maj. 13, min. 9, alt. 7 lines. 
Hab. New Georgia, Solomon group. 
This species, which I have received from Dr. James Cox of Sydney, 
New South Wales, is somewhat intermediate between H. aphrodite, 
Pfr., and H. purchasi, Pfr. It differs from the former in being 
much flattened above and very ventricose below, and especially in 
the form and amplitude of the aperture, and from the latter in tex- 
ture, form of spire, colour, and size. Dr. Pfeiffer erroneously gives 
New Caledonia as the habitat of H. aphrodite; its correct locality 
is San Christoval, Solomon Islands. H. purchasi comes from the 
Admiralty Islands. 
Hewtx (Grorrocuvs) aponis, n. sp. (Plate XLVIII. fig. 4.) 
Shell narrowly perforate, ovately conical, thin, obliquely sculp- 
tured with very fine irregular raised striee, rich orange-yellow colour 
throughout; spire conoidal; whorls 63, slightly convex, narrowly 
margined at the suture, the last angled at the periphery and flattened 
at the base; aperture rhomboidally oval, margins united by a thin 
callus, the right expanded and subreflected, the basal slightly re- 
flexed, forming an obtuse angle with the columella, which descends 
vertically and is callously reflected over the perforation. 
Diam. maj. 10, min. 83, alt. 13 lines. 
Hab. Bougainville Island, Solomon group (Brazier). 
This delicately orange-coloured species is intermediate in form 
between H. meta, Pfr., and H. gaertneriana, Pfr. 
He wtx (GEOTROCHUS) CHRULESCENS, n. sp. (Plate XLVIII. 
fig. 6.) 
Shell subperforate, conoidal, thin, obliquely striated and the lower 
whorls decussated by irregular undulating striz, bluish grey, with 
darker bands of the same colour, changing into pale yellowish olive 
above and at the base, the apical whorls being dark chestnut, and 
with a flesh-coloured band immediately below the suture, and a
