THE MOLLUSCA-——HEDLEY. 497 
Reported by Schmeltz from Samoa, Fiji, and Rarotonga ; by 
Melvill and Standen from Lifu ; and represented in this Museum 
from New Caledonia, 
LUCINA DIVERGENS, Philippi. 
Reeve, Conch. Icon., vi., 1850, Lucina, pl. vii., spp. 33, 37, 38. 
Common on the lagoon beach. 
Prof. von Martens has pointed out* that Philippi’s name enjoys 
two month’s priority over the better known JZ. fibula, of Reeve. 
He refers to it from Samoa and Fiji, and Melvill and Standen 
from Lifu. Material in this Museum show it to extend south 
along the Australian coast to Newcastle, New South Wales, and 
also to the Ladrones, New Hebrides, and New Caledonia. 
LUCINA OBLONGA, sp. nov. 
(Fig, 51). 
Shell small, but thick and strong, ovate, very inequilateral, in- 
flated. Colour, one specimen is white, the other pink. Sculpture 
—the umbones are smooth, the remainder closely and rather 
irregularly covered with numerous, raised, strong, concentric, ribs, 
narrower than their interstices ; faint radiating sculpture is barely 
visible in these interstices. Beaks prominent and much incurved. 
Lunule large, sharply impressed, sculptured by a faint continua- 
tion of the concentric ribs. Dorsal surface wanting the depression 
which characterises LZ. seminula and its allies. Interiorly the 
margin is most minutely crenulated. Length 3; height 3°75 mm. 
Two valves from the lagoon beach. 
Allied to Z. congenita, Smith,+ from which it differs by being 
narrower in proportion to height, more densely ribbed, and more 
inequilateral. 
CorBIS FIMBRIATA, Linne. 
Sowerby, Conch. Icon., xviii., 1872, Corbis, pl. i., sp. 1. 
A living specimen occurred under blocks of coral in the lagoon. 
Schmeltz quotes this from Fiji and the Pelews; Melvill and 
Standen from Lifu. It is in this Museum from Port Curtis, 
Queensland ; New Caledonia ; and Tonga.
