it probable that the correct determination should be L. 
hians since the remarks quoted do not apply to L. exusta 
as well as they would to that species which is now known to 
be so widely distributed.* 
L. hians extends from the China Sea to Torres Straits, 
thence down the Eastern Australian coasts to Moreton Bay 
and occasionally to Port Jackson ; and also easterly to New 
Caledonia. There can be little doubt but that it occurs 
in suitable situations in New Guinea, the Solomons and New 
Hebrides. Perhaps the Fijian L. anatina may be L. hians. 
At Noumea, both ZL. hians and L. anatina have been 
reported by Brazier (1879b, p. 402) and Francois (1891) 
respectively. The former mentioned in an earlier paper 
(1879a, p. 390) that DL. anatina was rather common in mud 
flats there. His material was, as already stated, L. hians. 
We have not had access to Francois’ original papers and 
therefore cannot pass definite opinion regarding his identi- 
fication, though we doubt the likelihood of L. anatina occur- 
ing in that locality. A brief note regarding the habits of L. 
hians in the China Sea was published by E. A. Smith 
(1878, pp. 820-1) who stated that it lived in mud or sandy 
clay at low water mark, its presence being indicated by the 
occurrence of oval orifices in the mud. 
The wide distribution of the species suggests that the 
larva has a fairly extended life and is able to adapt itself 
vo rather wide limits of temperature, since the adult occurs 
in tropical, sub-tropical and warm temperate waters in 
the Eastern Pacific. 
Inngula sp. 
Jukesf in his “‘ Voyage of the Fly” (1847, p. 144) 
gave the following account of a Lingula occuring near Cape 
York, North Queensland :—‘‘ I procured also from a muddy 
bay, to the east of Evans Bay, anumber of the genus Lingula 
alive. The shells lay buried in a close unctuous mud. 
*Dr. J. C. Cox in his privately issued “* Exchange list of Land and 
Marine Shells from Australia and the aijacent Islands” 1868, mention 
is made on p. 30 of No. 456, Lingula hians Swainson, Middle Harbour 
(Port Jackson)—fide Mr. C. Hedley. It was in this locality that Angas 
obtained his specimens. 
+We are indebted to Mr. C. Hedley for this reference.
