This species has also been recorded I'rom several localities in
North-east Australia by Mr. Brazier in his account of the Mollusca
of the ‘ Chevert ’ expedition.
25. Columbella scripta, Lamardc.
Hah. Port Molle, Queensland, and Prince of Wales Channel,
5-7 fms.
C. versicolor, Sowerhy, G. variegata, Menke, 0. hidentata, Mcuke,
and 0. tigrina, Duclos, appear to be synonymous with this species.
26. Columbella pardalina.
Lamarck; Duclos, Monog. ^pl. 2. figs. 13, 14; Kiener, pi. 4. fig. 3 ;
Reeve, Conch. Icon. figs. 75a-c.
/ /« 6. *Port Molle, on tho reef (Coppinger); Philippine Islands
(Cuming).
A single specimen from Port Molle is somewhat narrower than
specimens from the Philippines collected by Mr. Cuming.
27. Nassa coronata, Bruguih-e.
Hah. Port Molle, Queensland, on the beach.
A single specimen from this locality is of a uniform light brown
tint, with a blotch of a darker colour on the back of the body-
whorl.
28. Nassa thersites, Bruguiere.
Hab. Port Denison, on the beach.
29. Nassa algida, var.
Reeve, Conch. Icon. pi. 22. figs. 145«, b.
Hab. West Island, Prince of AVales Channel, Torres Straits (Gop-
pinger).
This pretty variety is not so broad a shell as the type, almost
white, upon which colour the rows of squarish, light brownish spots
appear moi'C consp)icuous than usual. There are nine whorls, of
which the two apical are smooth and convex, the four succeeding
ones strongly ribbed and transversely grooved a little beneath the
suture, the furrow dividing the ribs into two unequal parts. The
three last volutions are smooth, and a little more convex than the
sculptured ones above. The length is 20 millim., and the diameter
9 millim.
30. Nassa unicolor.
Buccinum Issve siuuatum, Chemnitz, Con.-Cab. iv. pp.54,59, pi. 125.
figs. 1194, 1195.
Buccinum unicolornm, Kiener, Coq. Viv. p. 60.
Buccinum unicolor, id. I. c. pi. 19. fig. 69.
Nassa (Alectrion) unicolor, A. Adams, P. Z. S. 1851, p. 106.
Nassa unicolorata, Reeve, Conch. Icon. fig. 17.
Nassa rutilans, Reeve, I. c. p. 147.
Nassa lævis, II. 8f A. Adams, Genera Mol. vol. i. pp. 116 & 119,
pi. 12. fig. 7.
Nassa (Zeuxis) unicolora, Kiener, Adams, I.e. p. 119.
Hah. Cape York, N. Australia (Jukes); Torres Straits (Bmzter) ;
Port Curtis and Port Molle, Queensland, 12-20 fms. (Coppinger);
Sir C. Hardy’s Island (Jukes).
New Zealand, the locality given by Beeve for N. rutilans, is probably
incorrect.
The operculum of this species is unguiculate, curved, with a terminal
nucleus and simple unserrated edges.
31. Nassaria suturalis, var.
Hindsia suturalis, A. Adams, Proc. Zool. Soc. 1853, p. 183 ; Sowerhy,
Thes. Conch, iii. pi. 220. figs. 15, 16 ; Kubelt,in Küster s Con.-Cab.,
Purpuracea, pi 77. tigs. 11,12.
Hindsia hituhercularis, A. Adams, P. Z. S. 1853, p. 183; Sowerhy,
I. c. tig. 5 ; Kohelt, I. c. tigs. 9, 10.
Nassaria recurva, Sowerhy, I. c. figs. 17, 18.
Nassaria sinensis, Sowerby, 'Thesaurus, figs. 8, 9; Kohelt, fig. 8.
Hah. Po rtD aiw in , North-west Australia, 8-12 fms. (C'ojjpwi^er);
China Sea, Philippine Islands, aud Ceylon (Adams and Sowerhy).
A single specimen from Port Darwin agrees precisely with the
variety sinensis. After a careful examination of the so-called species
which I have united above, I cannot detect any constant differences.
The above variety I believe to be founded on non-adult shells for
two reasons :—first, I find only six whorls, exclusive of the smooth
apical ones, being one less than in the typical suturcdis; and,
secondly, the aperture is larger, a result due to the less degree of
thickening of the labrum and columella. I t is true th at the suture
is less excavated, hut this concavity is variable in specimens undoubtedly
normal. The number of costæ is also inconstant, varying
from nine to twelve on a whorl ; in the former case, as might be expected,
being thicker than in the latter. The tuberculation and
liration on the columella depend for the amount of their development
upon age, adult shells having a larger quantity and a greater expansion
of the free columellar callosity than young specimens, but the
liræ within the outer lip, when countable, are generally about nine
iu number.
32. Phos scalaroides.
A. Adams; Soiverhy's Thes. Conch, vol. iii. pi. 221. fig. 13.
Hah. Prince of AA’alcs Channel, Torres Straits, 9 fms. {^Copping
er).
This form 1 cannot separate satisfactorily from P. qdicatus aud
P. te.vtilis, both of A. Adams ; and I am of opinion th at were tiie
