Locality.—Off Beachport, in 100 fathoms, 1 valve; 150 
fathoms, 2 valves. Off Cape Jaffa, in 90 fathoms, 20 valves; 
in 130 fathoms, 1 valve. South-west of Neptunes, 104 fath- 
oms, 3 alive and 26 valves, : 
Cuspidaria angasi, E. A. Smith. 
Neera angasi, n. sp., HE. A. Smith, Chall. Zool., vol. xiii., 
1885, p. 47, pl. ix., f. 2. Type locality.—Sta. 164n, off the coast 
of New South Wales, 410 fathoms, green mud. 
Dredged in 130 fathoms, off Cape Jaffa, 2 alive, 1 dead, 
3 valves. 
The ventral border and the lower border of the rostrum 
of the right valve lie within the margin of the left valve, 
while its dorsal borders, anterior and posterior, extend beyond 
those of its fellow. 
Cuspidaria exarata, n. sp. Pl. xii, figs. 6 and 7. 
Shell ovately-pyriform, subequilateral, thin. - Umbo 
round, inflated, directed backwards. Anterior dorsal margin 
slightly convex ; front end with a round, uniform curve; ven- 
tral border gently arcuate, joining the rostrum with a short 
incurvation. Post-dorsal slope nearly straight, barely in- 
curved; rostrum short, slightly tapering. Fossette small, 
directed obliquely backwards. Right valve has no distinct 
tooth, but a low lamina runs from the fossette backwards for 
half the length of the posterior slope, to make a shallow, nar- 
row furrow with its slightly more projecting border. The an- 
terior dorsal slope is bevelled on its inner side, and has the 
trace of a furrow within it near the fossette. Interior glis- 
tening, smooth, white, with subdistant radial translucent lines 
ending at the simple pallial line, Externally about twenty 
triangular concentric ribs, with sharp lirate summits and sub- 
lenticular concentric striz on their sides; the ribs become 
less costate and more lamelliform towards the ventral margin, 
and at the depression in front of the rostrum, over which they 
are only irregular vertical striz. Colour dull opaque white, 
with faint axial less white striations. 
Dim.—Antero-posterior diameter, 13°2 mm.; umbo-vent- 
ral, 75 mm. 
Locality.—35 miles south-west of Neptune Islands, in 104 
fathoms, one right valve perfect and the posterior half of a 
left valve, which if whole would be half as large again as the 
type. 
vA Diagnosis.—It closely resembles ©. trailli, Hutton, as 
figured by Mr. Hedley in Trans. N.Z. Institute, vol. 38, 1905, 
p. 72, pl. ii., figs. 9, 10, 11, dredged in 110 fathoms, east of 
the Great Barrier Island. It is also about the same size, mine
