ANNOTATED LIST. 149 
quently by the Alert at Port Molle, Queensland, but the former specimens were identified 
originally as S. rarispina and the latter as S. bicolor. They were subsequently examined 
by Mortensen and found to be belli. Semon also found the form near Thursday Island, 
and Déderlein based his supposedly new variety of sph@roides on Semon’s material. He 
later agreed with Mortensen that belli is entitled to rank as a distinct species. 
Salmacis dussumieri. 
Agassiz and Desor. 1846. Cat. Rais. Eich., p. 359 (55).—Déderlein. 1903. Jena. Denkschr., 8, pl. Ixiii, figs. 5-5c. 
The inclusion of this species in the present list is due to Mortensen’s (1904) statement 
that one of the small specimens of Salmacis taken by the Challenger at her Station 186 
(Torres Strait) is dussumiert. He also says that dusswmieri was taken by the Alert at Port 
Denison, Queensland, and identified by Bell as S. sulcata. The known range of dusswmieri 
is from Mozambique to southern Japan and eastern Australia. Whitelegge (1889) lists it 
from Port Jackson, but I doubt if it occurs so far south. The specimens taken on the coast 
of New South Wales by the Endeavour which look like dussumieri appear to be a distinct 
species, oligopora. 
Salmacis virgulata alexandri. 
Salmacis alexandri Bell. 1884. Alert Rep., p. 118. 
Salmacis virgulata var. alexandri Déderlein. 1903. Jena. Denkschr., 8, p. 712, pl. lxii, figs. 1, 3-7. 
Salmacis virgulata alexandri Déderlein. 1914. Ech. Siidwest. Aust., p. 454 
Although typical examples of alexandri are easily distinguished from typical virgulata, 
there is no doubt that the two forms intergrade along the northeastern coast of Australia. 
True virgulata has been taken as far south as southern Queensland, while we found 
at Badu, on an eel-grass bottom, a small but typical specimen of alexandri, the form 
really characteristic of the coast of New South Wales. We did not find a Salmacis at the 
Murray Islands. 
Temnotrema bothryoides. 
Temnopleurus bothryoides Agassiz and Desor. 1846. Cat. Rais. Ech., p. 360 (56). 
Pleurechinus bothryoides Déderlein. 1903. Jena. Denkschr., 8, p. 706, pl. Ixi, figs. 1, 2. 
Temnotrema bothryoides H. L. Clark. 1912. Mem. Mus. Comp. Zodl., 34, p. 318. 
Temnotrema decorum Déderlein. 1914. Ech. Siidwest Aust., p. 459. 
Although Torres Strait seems to be the particular home of this little sea-urchin and 
the Challenger, the Alert, and Semon all found it there, we failed to meet with it, much to 
my regret, as I have never yet seen a specimen. The Siboga took it at the Aru Islands, 
and Déderlein (1914) records it from Sharks Bay, West Australia. There is no occasion 
for abandoning the specific name bothryoides, as Déderlein (1914) does. He apparently 
fails to consider that the use of a specific name in one genus does not invalidate its use in 
another. Agassiz had a right to call a sea-urchin Temnopleurus bothryoides even though 
Leske had called something else Cidaris bothryoides, and Agassiz’s specific name persists, 
no matter how frequently it is shifted from one genus to another. Déderlein’s proposed 
substitute name is thus a pure synonym. 
Temnotrema maculata. 
Pleurechinus maculatus Mortensen. 1904. Siam. Ech., p. 89, pl. i, figs. 4, 14. 
Temnotrema maculata H. L. Clark. 1912. Mem. Mus. Comp. Zodl., 34, p. 318. 
Mortensen (I. c.) states that he has seen specimens of this species brought from Torres 
Strait by Haddon, and that it also occurs at Hongkong, on Macclesfield Bank, and at five 
Siboga stations in the East Indies. He suggests that it may be only a form of bothryoides, 
but as I have seen neither species I have no opinion on the point to express. It would be 
interesting to know if Haddon secured his specimens at Mer, where he spent some weeks.
