THE MOLLUSCA—HEDLEY. 50 
Smith reports this from Torres Straits. In this Museum it is 
represented from Fiji; New Oaledonia ; Moreton Bay, Queensland; 
and St, Vincent’s Gulf, South Australia. 
NAUSITORIA AURITA, Sp. Nov. 
(Fig. 56). 
Shell distinguished by an auricle which is much recurved out- 
wards and above; within, it is raised above the surface of the 
valve. This character is illustrated by Fig. 56, showing exterior 
and interior of the right valve. Ventral or median area rather 
broad. Apophyses short and broad. Hinge tubercle bifid. Length 
9, breadth 9 mm. Palettes unknown.

A log, recognised by a bushman of our party as kauri (ante p. 
40) which came ashore at Funafuti, had been bored by this 
mollusc, On breaking the wood up with an axe, I found the 
only vestiges left of the animal to be a pair of valves broken at 
the ventral tips, which I found in a burrow. 
Mr. R. C. Rossiter afterwards generously presented me with a 
couple of perfect valves, specifically identical with these Funafuti 
shells, which he collected at Noumea, New Caledonia. 
An ally of this seems to be a species of unknown origin named 
by Sowerby Teredo campanulata, that is however apparently 
narrower in the ventral portion, and even more produced and 
recurved in the auricle. 
I recently examined* certain Australian shipworms, and re- 
marked that they differed from Teredo generically. For their 
reception I selected the genus Calobates, Gould (1862), revised 
the characters of that genus, and subordinated to it Vausitoria, 
Wright (1864), and Zyrodus, Gould (1870). It unfortunately 
escaped my attention that Tapparone Canefri had already pointed 
outt that Calobates, as a generic term, had been twice preoccupied
