1869.] MR. G. F. ANGAS ON NEW SPECIES OF HELICID. 625 
similar one at the periphery with a narrow dark chestnut line in the 
middle ; spire conical, rather obtuse at the apex ; whorls 44, slightly 
convex, the last descending in front, angled at the periphery ; aper- 
ture diagonal, sublunar ; peristome white, margins converging, the 
right scarcely flexuous, expanded, the basal one arcuate, reflexed. 
Diam. maj. 9, min. 8, alt. 8+ lines. 
Hab, Guadaleanar Island, Solomon group. 
Herix (Georrocuus) DEIDAMta, n. sp. (Plate XLVIII. fig. 3.) 
Shell perforate, turbinate, rather solid, shining, obscurely obliquely 
striated, yellowish olive, gradually becoming purple towards the apex, 
with an opaque white band joining the suture below ; spire convexly 
conical; whorls 63, convex, attenuated at the upper part, the last 
non-descending, slightly angled at the periphery and a little flat- 
tened at the base; aperture diagonal, subovate ; peristome purplish 
black, reflexed, right margin flexuous, excavated behind, columellar 
margin curved, sloping, and broadly covering the perforation. 
Diam. maj. 11, min. 10, alt. 14 lines. 
Hab. Ysabel Island, Solomon Group. 
In form this species nearly approaches H. acmella, Pfr.; but the 
spire is more turbinate and peculiarly contracted towards the apex, 
the last whorl is less convex, and the outer lip more flexuous. The 
painting, moreover, is entirely different, and uniform in all the spe- 
cimens that have come under my notice. 
Heirx (GroTROCHUS) HARGREAVESI, n. sp. (Plate XLVIII. 
fig. 2.) 
Shell imperforate, turbinate, rather solid, obliquely faintly striated, 
creamy white sprinkled here and there with small purplish semi- 
pellucid spots, and ornamented with a narrow suffused chestnut band 
above and below the suture and a broader one at the periphery ; 
spire turbinate, apex very slightly obtuse ; whorls 6, a little convex, 
the last abruptly descending, convex below, with a broad suffused 
chestnut band in the middle ; aperture very oblique, truncately oval ; 
peristome black, thickened, the right margin very slightly expanded 
and sinuous, the columellar margin a little reflexed, obliquely de- 
scending, spread over the body-whorl, and furnished within with a 
long straight callus. 
Diam. maj. 12, min. 10, alt. 104 lines. 
Hab. Bougainville and Shortland’s Islands, Solomon group 
( Brazier). 
Varieties of this species occur in which the chestnut bands are 
wanting. 
Hewrx (GEoTROCHUS) HERMIONE, n. sp. (Plate XLVIII. fig. 5.) 
Shell perforate, ovately conical, rather thin, very finely obliquely 
striated, purplish black, with a pale straw-coloured band below the 
periphery of the last whorl, and sometimes with a second band 
between the periphery and the suture; spire conical, apex rather 
obtuse ; whorls 63, a little convex, the last angled at the periphery,
