426 MOLLUSCA FROM THE HOPE ISLANDS, N. QUEENSLAND, 



Anim. s. vert. vi. 1819, p. 24. Cardita semiorbiculata Reeve,. 

 Conch. Icon, i., Cardita, 1843, PI. iii., sp.lO. 



A living specimen was taken on the reef at low-water, and a 

 separate valve was dredged in 5-10 fathoms. It has not been 

 seen before from Queensland, and, but for Lamarck's remark^ 

 *' Habite .... la Nouvelle Hollande " in the above citation, I 

 should have claimed it as new for Australia. This is the type of 

 Bolten's subgenus Beguina. 



CoDAKiA REEVEi Deshayes. 



Lucina reevei Deshayes, Moll, de Reunion, 1863, p. 19, PI. iii., 

 f.8,9. 



On the beach at Hope Island I gathered some specimens which 

 answer fairly to Deshayes' account. They differ by having 

 rather fewer and stronger ribs, and measure 18 mm. as against 

 25 mm. of the type. The species has not before been noticed 

 from Australia. 



Phacoides eucosmia Dall.

 2nd ser., iv. 1837, p. 341, PJ. xvi., f.l4; nor L. jnsum D'Orbigny, 

 Pal. France, Terr. Ciet. iii. 1841, P1.281, f.3-5; nor L. pisicni

This species did not occur in the Hope Island collection. It 

 is introduced for comparison with other species, and to aid in the 

 perplexities of its nomenclature. The individual figured is 5 mm. 

 long. I dredged it in 5 fathoms, soft black mud, in Van Diemen's 

 Inlet, Gulf of Carpentaria, where the species was abundant. 

 Other localities in the same Gulf, where I met with it, are 

 Mornington and Porsyth Islands, and off the mouth of the 

 Batavia, Horsey, and Norman Rivers. I have not yet found it 

 on the Pacific Codst.
