Station :—The under surface of loose boulders at low tide level. 
Hub. N.S. Wales:—Bottle and Glass Reef, Port Jackson (type, 
Brazier); Botany Heads (Hargraves). Victoria :—Western Port (Gabriel). 
South Australia :—St. Vincent Gulf (Verco). Western Australia (Museum 
Collection). Queensland :—5 to 10 fathoms, Hope Island (self). 
DAPHNELLA CESTRUM sp. nov. 
(Plate liii., fig. 160.) 
Clathurella debilis Brazier, Proc. Linn. Soc. N.S.W., i., 1876, p. 155 (not 
Clavatula debilis Hinds, Zool. “ Sulphur,” i., 1844, p. 17, pl. v., fig. 16). 
Shell acicular, thin, but boldly sculptured, contracted at the suture, 
excavate at the base; canal produced and recurved. Colour pale yellow, 
with two rufous brown zones, one above, the other below the periphery, 
both interrupted by the ribs; columella lilac; apex salmon buff. Whorls 
eleven, including three on the protoconch. Suture impressed, undulating. 
Base defined by a sharp angle which continues the horizon of the suture. 
Sculpture :—The fasciole area is without spirals, but is crossed by radial 
erescentic wrinkles; spirals may amount to twenty-seven on the last 
whorl, those on the periphery being alternately larger and smaller; seven 
of these ascend the penultimate whorl; all of these over-ride the radials ; 
the radials are thin, high, variciform riblets, perpendicular, discontinuous, 
extending from below the fasciole to the angle of the base, and set at 
eight to a whorl. Aperture:—Onuter lip simple; sinus adjacent to the 
suture, deeper than broad, rounded; inner lip with a thin callus; canal 
open, produced, and recurved. Length 10. mm., breadth 3 mm. 
This shell differs from the figure of CO. debilis, with which Brazier 
had identified it, by fewer bolder ribs and excavate base. In sculpture it 
approaches Daphnellu eleguntissimu Schepman,” from which it differs by 
the narrower form, hollow base, and produced canal of D. cestrum. 
Hub. Queensland :—20 fathoms, Darnley Island (type, Brazier); 20 
fathoms, Endeavour Reef (McCulloch); 15 fathoms, Palm Islands (self). 
DAPHNELLA CHEVERTT sp. nov. 
(Plate liii., fig. 161.) 
Daphnella pluricarinata Brazier, Proc. Linn. Soc. N.S.W., i., 1876, p. 159 
(not Plewrotomu pluricarinata Reeve, Couch. Icon., i., 1845, pl. xxii., 
fig. 288). 
Shell small, thin, narrow-fusiform, subturreted, blunt at apex, and 
attenuate anteriorly. Colour ochraceous-buff, gradually becoming darker 
towards the apex. Whorls six, of which three compose the protoconch, 
the last whorl rounded, the earlier ones angled at the shoulder. Sculpture 
delicate. The radials are close thin lamelle which do not surmount the
