APPENDIX—MOLLUSCA. 
CmcUM AMALTHEANUM, sp. nov. 
(Fig. 75.) 
Shell small, a twisted cone, performing about 
a third of a revolution, rapidly enlarging. White 
very glossy, with about twenty, faint rib rings. 
Aperture circular, slightly contracted behind 
the everted lip. Septum gradate, with three 
steps, arising deep within the collar, peaked on 
the outer side. Length ‘76; breadth at aperture 
‘34 mm. 
Two examples dredged at 56 fathoms, north 
of Pava Islet. 
The contour of this species isolates it from 
any co-generic type. 
CmCUM LEGUMEN, sp. nov. 
(Fig. 76.) 
Shell pod-shaped, arched on one side, nearly 
straight on the other; rounded in transverse 
section on the arched side and flattened on the 
straight. Colour white. Sculptured by fine 
growth rings, surface glossy and shining. At the 
aperture slightly contracted, mouth oval, flattened 
on one side. Septum much exserted, peaked on 
the curved side. As foreshortened to show the 
aperture in my drawing, the shell has a quaint 
resemblence to a tobacco pipe. Length 1:5; 
breadth 64 mm. | 
Dredged at 36 fathoms N. 30° W. of Pava Islet 
and again at 150 fathoms off Beacon Islet (Funamanu). 
The only species at all resembling this, figured in 
Tryon’s Manual, is C. nitidum, Stimpson, than which it 
is less inflated. 
TRIFORIS ASPERRIMUS, Hinds. 
(Fig. 77.) 
Hinds, Ann. Mag. Nat. Hist., xi., 1843, p. 18; Tryon, 
Man, Conch., ix., 1887, p. 181, pl. xxxviii., fig. 6. 
A single, probably immature, specimen of twelve 
whorls, in length 2:92 and in breadth -56 mm., which 
was dredged in 36 fathoms, north of Pava Islet is thus 
doubtfully determined. The species appears not to have 
been seen since Sir Edward Belcher dredged his unique 
specimen in eight fathoms on the Papuan coast.
