LINTHIA AUSTRALIS. 
Desoria australis, Gray, 1851. Ann. Mag. Nat. Hist. (2), vol. 7, p. 132. 
Linthta australis, A. Agassiz, 1872. Rev. Ech. pt. I, p. 138. 
A single bare test (No. 5005) from Fremantle Beach shows 
that this is a West Australian species, although it was previously 
known only from South-western Australia and Tasmania. It is 
still a rarity in Museums and specimens with spines are greatly to 
be desired. 
ECHINOCARDIUM AUSTRALE. 
Gray, 1851. Ann. Nat. Hist (2), vol 7, p. 131. 
It is not at all surprising to find this widely distributed species 
in the collection. 
Safety Bay, W.A. Three specimens, Nos. 239, 240, 241. 
BREYNIA AUSTRALASIAE. 
Spataugus australasiae, Leach, 1815. Zool. Misc., vol 2, p. 68. 
Breynia australasiae, Gray, 1851. Ann. Mag. Nat. Hist. (2), vol. 7, p. 131. 
The larger of these bare tests (No. 4562) measures 120 mm. long, 
by 100 mm. wide and 60 mm. high, showing that Breynia grows to 
a larger size than has hitherto been known. Although these speci- 
mens differ from those taken at Lord Howe Island, N.S.W., by the 
very characters on which Gray based his Breynia dcsorii, other 
specimens in the M.C.Z. collection are intermediate and I do not 
feel satisfied that desorii is a valid species. 
Abrolhos Islands, W.A. One specimen, No. 4562. 
Fremantle Beach, W.A. One specimen, No. 5004. 
HOLOTHURIOIDEA. 
The bolothurians unfortunately are not in nearly as good con- 
dition as the dry echinoderms, and it is impossible to identify one- 
third of them. They seem to have been in formalin and several 
are more or less decalcified. Nevertheless all are of interest for we 
have hitherto known almost nothing of the holothurians of the 
western half of Australia — indeed we know little enough of those of 
the eastern coast. Of the six identified species, three belong to the 
genus Pentacta (=Colochirus) and one of these seems to be a 
remarkable new species, which, should the characters shown by 
these specimens prove real and constant, might well be given a 
genus of its own. The other new species is an apodous holothurian 
of the genus Caudina.
