28 THE ECHINODERMS OF TORRES STRAIT. 
LUIDIID£E. 
Luidia forficifera. 
Sladen. 1889. Challenger Ast., p. 258; pl. xliv, figs. 5, 6; pl. xlv, figs. 5, 6. 
This sea-star has not been found in the Torres Strait region since the Challenger found 
it near Booby Island, but both the Thetis and the Endeavour took Luidias off the coast of 
New South Wales which seem to be forficifera. The species has been recorded twice from 
the Mergui Archipelago, but has not yet been reported from anywhere in the East Indies. 
Luidia maculata. 
Miller and Troschel. 1842. Sys. Ast., p. 77.—Koehler. 1910. Ast. et Oph. des fles Aru et Kei, p. 267, pl.

A single specimen of this large and easily recognized sea-star was taken by Semon 
near Thursday Island. It has been recorded from the coasts of eastern, southern, and 
western Australia, while its northward range reaches China and Japan. Westward it 
extends to Mozambique, but it does not seem to occur anywhere east of Japan, the Philip- 
pines, Torres Strait, and the coast of New South Wales. It would therefore appear to be 
a typically Indian Ocean species, which has not passed into the Pacific except along the 
coasts just mentioned. Its bathymetrical range is considerable, for while it has been 
recorded from “between tide-marks,’’ Goto (1914) reports a specimen from a depth of 
640 meters. There are usually 7 or 8 rays, but occasionally there are only 6, while sometimes 
there are 9. The largest I have seen has the rays 250 mm. long, but Koehler (1910a) 
records one from Balasor Bay, India, in which R =350 mm. 
GONIASTERID£E. 
Iconaster longimanus. 
Astrogonium longimanum Mobius. 1859. Neue Seesterne, p. 7, pl. i, figs. 5, 6. 
Iconaster longimanus Sladen. 1889. Challenger Ast., p. 261. 
The locality from which Moébius’s type specimen came is unknown, but the one in 
the Paris Museum, listed by Perrier (1876), is supposed to be from the Strait of Malacca. 
The Alert took specimens in Prince of Wales Channel, Torres Strait, and at the Percy 
Islands, North Queensland. Semon secured a specimen at Thursday Island, and there is 
a specimen in the Museum of Comparative Zoélogy from Adolphus Island, Torres Strait. 
Bell (1894) records the species, without comment, from northwestern Australia, but he 
gives no definite locality. Bedford (1900) records a specimen from near Malacca. Koehler 
(1895) lists a specimen from the Sunda Islands, but there is no clue as to the exact lo- 
cality. He also (1910) lists a specimen from the Aru Islands. Apparently the species is an 
East Indian one, ranging from the Strait of Malacca to northern Australia as far south as 
Percy Island. 
Goniodiscaster coppingen. 
Pentagonaster coppingeri Bell. 1884. Alert Ech., p. 128. 
Goniodiscaster coppingeri H. L. Clark. 1909. Bull M. C. Z., 52, p. 110. 
(Plate 23, figures 1 and 2.) 
Bell’s specimens were from Port Curtis, Queensland, and from Prince of Wales Chan- 
nel, Torres Strait. The specimen here figured is in the Museum of Comparative Zodlogy 
collection, and came from Adolphus Island, near Cape York. Apparently the species is 
peculiar to northeastern Australia and has not been found elsewhere.
