188 THE ECHINODERMS OF TORRES STRAIT. 
This species is fairly common at Mer, and what seems to be the same thing was also 
found at Badu. The geographical range of the species is great, from the Red Sea and 
Zanzibar on the west to the Caroline and Samoan Islands on the east; it is reported from 
southern Japan (Izu). Bell (1884) lists it from Port Molle, but as he identified Thelenota 
ananas (Jaeger) for Saville Kent (1893) as Stichopus variegatus, it is obvious this record 
can not be trusted. 
On October 13, 1913, a Japanese diver brought up from 18 fathoms off the north- 
western reef at Mer a holothurian over 700 mm. long and 125 mm. thick, which our Murray 
Island fishermen said was a ‘‘curry-fish.’’ This proved to be a specimen of variegatus, but 
none of the béche-de-mer sold as curry-fish, which I examined, were specimens of Stichopus.

This species ranges from Zanzibar to Fiji, north to the Riu Kiu Islands and south to 
Port Denison, Queensland. Semon took it near Thursday Island, but we did not meet 
with it at any point. There are specimens in the Museum of Comparative Zodlogy from 
Ponape, Caroline Islands, and Tongoa, New Hebrides. Béche-de-mer fishermen call this 
“‘red-fish,”’ as they do A. mauritiana. 
Actinopyga lecanora.

This is the ‘‘stone-fish”’ of béche-de-mer fishermen in Torres Strait and is common 
throughout the region. We found it several times at the Murray Islands, generally on 
the under surface of large rock-fragments. The range of the species is from Mauritius to 
Tongatabu, north to the Riu Kiu Islands, south to the Great Barrier Reef. 
Actinopyga lubrica. 
Miilleria lubrica Sluiter. 1894. Jena. Denkschr., 8, p. 104. 
This curious species is based on two specimens only 42 mm. long taken by Semon 
near Thursday Island. The calcareous particles (aborted tables only) are absolutely 
unique in the genus. The species has not been met with since first described. 
Actinopyga mauritiana. 
Holothuria mauritiana Quoy and Gaimard. 1833. Voy. Astrolabe, 4, p. 138. 
Actinopyga mauritiana Bell. 1887. Sci. Trans. Roy. Dublin Soc., (2), 3, p. 653, pl. xxxix, fig. 1.—Fisher. 1907. 
Proc. U. 8. Nat. Mus., 32, p. 648, pl. Ixvii, figs. 1-1d. 
This species is easily confused in life with A. lecanora, and though the béche-de-mer 
fishermen call it ‘‘red-fish,’”’ I think their line of division between red-fish and stone-fish 
would not coincide with the line between lecanora and mauritiana. At Mer, mauritiana 
seems to be less common than lecanora, but Kent (1893) considers the latter rare on Queens- 
land shores and the former ‘‘abundant.”’ Pearson (1914) considers mauritiana the com- 
monest member of the genus. It certainly has the most extensive geographical range— 
Mozambique to the Red Sea on the west, Hawaii, the Marquesas and the Paumotus on 
the east, the Riu Kius on the north, and Fiji on the south. Fisher’s account (1907) of the 
species as it occurs at Hawaii is very complete and satisfactory. 
' The usual quotation of “p. 403” for this combination of Actinopyga and lecanora is a mistake. Actinopyga is 
proposed as a substitute for Muilleria on p. 403, but it is not used in combination with lecanora until the figures of the 
latter appear on pl. xxv,
