obtained it from Elphinstone Island, Mergui Archipelago (Journ.

NAUSITORIA MANNI, Wright, 1865. 
Reference.—Trans. Linn. Soc., XXV., p. 565, Pl. LXV., Figs.

Discovered at Singapore and recently detected at Cooktown, 
Queensland, in association with the preceding (Hedley, Records

NAUSITORIA SAULII, Wright, 1865. 
Synonym.—TZredo fragilis, Tate. 
Reference.—Proc. Linn. Soc., N.S. Wales, XXIII, p. 94, Figs, 
7-9. Distinguished by imbricating jointed pallets. 
This species was described first from Port Phillip, Victoria. It 
has since been found at Adelaide, Launceston, Sydney, and the 
Bellenger River: Probably this is the species which Denison 
(Proc. Roy. Soc. Van Diemen’s Land, 1852, p. 74) and Tenison 
Woods (Proc. Roy. Soc., Tasmania, 1877, p. 47) mistook for 
Teredo navalis. N. sauliv seems to be always smaller than J. 
edax, with which it is frequently associated.

by fork-shaped pallets. 
' Occurs from Auckland to Dunedin, New Zealand. It is im- 
probable that Smith was correct in identifying with this species

“Challenger” expedition off Cape York, Queensland.
