seen, some still showing their duplicate nature. The hinge is composed of two 
straight rows of teeth, meeting angulately in the juvenile, separated by the 
ligamental area intruding in the adult. The inside colouration is white in the 
juvenile but mostly marked with brown in the adult. The crenulation of the 
edge is deep and regular when young but less marked though still definite in 
the adult. 
Length 37 mm. ; height 38 mm. ; diameter 12 mm. 
Habitat : North Queensland (only dredged). Type from Albany Passage, 
9-12 fathoms. Also collected at Michaelmas Cay, 9-12 fathoms. 
Probably Lamarck's vitreus came from West Australia, as Odlnier (Ivungl. 
Svensk. Vet. Akad. Handl., Bd. 52, No. 16, p. 22, pi. 1, ff. 12-13, 1917) has 
figured a young specimen from oil Cape Jaubert, North-west Australia, which 
differs from ours in detail, and in shape fits Reeve’s figure of Lamarck’s type 
well. 
Family TELLINIDA3. 
A curious Tellinid was included in a fine collection brought back by Mr. 
Melbourne Ward from the islands in the Whitsunday Passage. It proved to 
be identical with a shell from New Caledonia identified in London as Tellinungula 
bruguU.fi Hanley. Tellina bruguieri was described from the island of Panhay, 
Philippines, and the Australian specimen differs from the description and figure 
in the shorter posterior side and the more produced anterior edge, the concentric 
sculpture more pronounced and the radial nearly obsolete ; the teeth are even 
larger and the pallial sinus of greater extent. These features can be 
distinguished with the subspecific name refecta nov. Regarded as referable to 
the genus Macoma on account of its lack of lateral teeth, it was separated by 
H. Adams (Proc. Zool. Soc. 1S60, p. 369) with the name Macalia, introduced 
for it alone. Twelve years later Romer, monographing the Tellinidae in the 
Conch. Cab. ed. Kuster, Bd. x, Abth. 4, p. 268, 1872, and ignorant of H. Adams’s 
action, again recognised its distinction, giving the name Tellinungula to the 
section for the single species. Bertin in his monograph of the Tellinidse left it 
in Macoma, with which genus it has probably no close affinity ; and Dali, 
without comment, in the Trans. Wagner Free Inst. Science, vol. iii, p. 1044, 
1900, allowed it as of sectional value under the subgenus Macoma, probably 
from no close attention to the shell, as it is of striking appearance, recalling 
Tellina inflata Gmelin and Tellina spedabilis Hanley. The latter has been 
classed under Metis, which name, long known to be preoccupied, has, at the 
second attempt, been emended to Apolymelis by Salisbury (Proc. Malac. Soc. 
(Lond.) vol. xviii, p. 258, Nov. 1929). Hanley’s spedabilis does not appear to 
me to be congeneric with meyeri, the type of Apolymetis, and is therefore here 
differentiated with the new generic name Leporimetis. Hanley’s Tellina spedabilis 
and bruguieri were both described in the Proc. Zool. Soc. (Lond.) 1844, pp. 
141-2, Dec., from the Philippine Islands.
