MEMOIRS OF THE QUEENSLAND MUSEUM. 
The hinge-teetli of these shells differ appreciably from those of M. obesa 
Reeve above mentioned, and therefore I introduce the genus Telemartra , naming 
M. obesa Reeve as type. 
Smith described a new species, Mactra queenslandica (id. ib., p. 1 48, fig. 
in text), from Sandgate, S.Q., and for this I propose a new generic name 
Colorimactra , and describe an allied .species as — 
Colorimactra florens sp. nov. 
(Plate XXXI, fig. 16.) 
Shell small, ovately trigonal, a little inequilateral, somewhat compressed. 
Colour greyish purple, shining, colour zoned through growth lines; deeper 
near the umbones and then at the ventral margin; inside dark reddish purple, 
darker and duller internally, shining towards the edges. Anteriorly rounded, 
the lunule is not well defined save by radial lira? ; posteriorly, a strong sharp keel 
is prominent, the escutcheon in the keeled area being boldly radially lirate ; the 
line stopping before the keel is reached but not bounded by any raised line ; 
otherwise the shell is smooth and shining, the almost imperceptible growth lines 
showing a little strength near the margins. The pallial sinus is short and rounded ; 
hinge-teeth as in M. queenslandica Smith. 
Length 23 mm. ; height 19 nun. ; depth of conjoined valves 9 mm. 
Collected by the Rev. Percy Hubbard at Innisfail, North Queensland. 
Differs from ill. queenslandica Smith, of which it may be the northern 
representative, in its stronger posterior angulation and the convex, not concave, 
Junular anterior side. 
When Dali provided a SynopPR of the Genera of Recent and Tertiary 
Mactridse (Proe, Malac. Soc. (Lond.) i, pp. 203-213, March 1895) he allowed a 
subfamily Lutrariina? with genera Lutraria (three sections, Lutraria , Gonio- 
mactra, and Lutrophora), Tresus, Standella (with subgenus Eastonia) , and 
Heterocar dia. Goniomactra had been introduced for the Australian Lutraria 
impar Deshayes (Reeve, Conch. Icon., ii, pi. iii, sp. 10, 1854), which is decidedly 
a distinct form. 
lied ley’s Queensland list allowed Lutraria arcuata, clongata , impar, 
oblonga , and philip'pinarum with Standdla mcobarica . The list was a compila- 
tion, so that the three names arcuata, oblonga, and philippinarum are found to 
refer to the same species, and the best name for that appears to be australis, 
given by Deshayes and first published by Reeve (Conch. Icon., ii, pi. iii, sp. 8, 
1854: Moluccas). Gray's Lutraria elongata (Mag. Nat. Hist. (Jard.) i, 374, 
1837) was anticipated by Muenster (N. Jahrb. f. Min. 435, 1835), and may be 
here renamed Lutraria (Lutromactra nov.) imp edit a nom. nov. 
Standella hubbardi sp. nov. 
(Plate XXX, figs. 11, 12.) 
The species Stan della nicobarica of Iledlev's Queensland list must bear 
the new name Meropesta mcridiana, as, although it has a close resemblance to 
the Indian shell, when compared it is seen to differ in shape, being higher with 
the posterior end more rounded, not attenuate, the wrinkled area much less in
