THE MOLLUSCA HRDLEY. 507 



Smith reports this from Torres Straits. In this Museum it is 

 represented from Fiji; New Caledonia; 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. 



Fig 56. 



A log, recognised by a bushrnan 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 Nausitoria, 

 Wright (1864), and Lyrodus, Gould (1870). It unfortunately 

 escaped my attention that Tapparone Canefri had already pointed 

 outf that Calobates, as a generic term, had been twice preoccupied
