[Barbatia Carpenteri, Dunker. 
Ref. and Syn.—Anomalocardia Carpenteri, Dunker, Nov. 
Conch., t. 30, figs. 7-9, 1860. Arca (Barbatia) radula, EK. A, 
Smith, Challenger Lamellibranchiata, p. 260, t. 17, figs. 3-3b. 
1885. 
There can be no doubt that the above-quoted names refer to 
one species only; indeed, the types of each are from the same 
locality—Port Philip Bay, in Victoria. The name employed in 
the Challenger Report is adopted from the M.S. of A. Adams, in 
the Cumingian Collection, and its earliest appearance in print is 
due to Angas, in Proc. Zool. Soc., 1865, p. 655—thus five years 
after Dunker’s diagnosis. Dunker’s name must in all fairness be 
accepted. | 
Lima squamosa, Lamarck. 
If the difference in the number of ribs be a reliable distinctive 
character to separate ZL. squomaso and L. multicostata (there 
being about 24 to the former and about 36 to the latter), then 
L. squwamosa wust be included in our local list; as Mr. Adcock has 
collected two medium-sized valves on the beach at Port Lincoln. 
both species are recorded from the tropical seas of Australia, but 
I do not know of an authentic occurrence of LZ. sqguamosa in 
any other part of Australia. It is true that Menke records the 
name for Swan River, but it is not certain if it be correctly 
applicable, as at the time when Menke wrote his ‘ Molluscorum 
N. Hollondiz,” the Sowerbian species had not been separated 
from that of Lamarck. 
Pecten undulatus, Sowerby. 
Ref.—Thes. Conch., vol. i, p. 60, t. 19, figs. 206, 207; ad, 
Reeve, Conch. Icon., t. 20, fig. 73. 
A white, triangularly orbicular, depressed shell, ornamented 
with seven or eight broad rays, which are radially ribbed; the 
interstitial spaces with shagreen-sculpture. About an inch-and- 
a-half in diameter. 
Off Corney Point, in 17 to 30 fathoms; and Investigator’s 
Straits, in 15 fathoms (Dr. Verco). Also Port Phillip Bay!; off 
East Moncoeur Island, Bass Straits (Challenger Report), and 
Tasmania. 
[Terebratulina eancellata, Koch. 
By a typographical error, this species was quoted in vol. IX. 
p- 110, as Zerebratella cancellata. |
