as far as they have been noted, agree with L. hians. The 
ratio of length to breadth in the case of the latter (length 
1 inch 10 lines, breadth 9 lines—Davidson 1888, p. 217) is 
also 2.44. 
We have no hesitation in placing L. hirundo as a 
synonym of L. hians and consider it to be based on young 
specimens. JL. hians is definitely recorded from a number 
of Queensland localities, including Port Curtis. 
L. hians Swainson. 
Syns.* L. hirundo Reeve, Port Curtis. 
L. hians Brazier 1879, Pt. Jackson, Pt. Curtis, 
Noumea. 
L. hians Angas 1867, Pt. Jackson, New Cale- 
donia, Fiji. 
L. hians Shirley 1910, Moreton Bay. 
L. rostrum Hedley 1916, in part; 1917, Pt. 
Jackson.

. exusta Tapparone—Canefri 1873, Australia.

This species was recorded from Sydney Harbour by 
Angas (1867, p. 935) and Brazier (1879) and is mentioned 
by Whitelegge (1889, p. 295), but Hedley, as already stated 
earlier in this paper, regarded the specimens as belonging 
to L. anatina (=L.rostrum). Angas gave a brief description 
of the shell which was found in sandy mudin Middle Harbour, 
Port Jackson, mentioning as additional localities, Fiji, 
New Caledonia, China and the Philippines. Brazier (18796, 
p. 402) referred to its presence in Port Curtis as well as in 
Port Jackson and New Caledonia, stating (1879a, p. 390) 
that L. hians was the only species found in Sydney Harbour 
and was so rare that he had found only one living specimen 
in 25 years’ collecting there. Thanks to the courtesy and 
assistance of Mr. C. Hedley, we were able to re-examine 
Brazier’s material from Noumea, and found it to be L.
