444 Happon—The Actiniaria of Torres Straits. 
they have a decidedly beaded appearance, and resemble the figures of Heteractis 
aurora, Q. & G. 
Colowr.—Column cream below streaked with red-lead, blotched or spotted 
inferiorly ; upper portion pale greenish or bluish grey; suckers and marginal 
crenulations white; disk, central area cream colour, with radial dark-brown lines, 
which divide into two after a definite plan, but in an irregular manner. There 
are 48 (?) splashes of a clearer ground colour on the disk between the lines which 
indicate the mesenteries of the inner series of tentacles; beyond them the colour 
is more dusky; the area of the inner series of tentacles is dark brown; a white 
spot in front of each of the inner series of tentacles passes round the base, and 
extends peripherally as two broad white bands. The two inner cycles of the inner 
series of tentacles have a distinctly madder tinge on their oral aspect, with a green 
sheen. Marginal tentacles transparent brown aborally, cream colour orally, the 
swollen portions spotted in the middle. 
One specimen, with a greenish grey in the upper part of the column, had a 
disk of variegated greenish grey, darker towards the centre, paler peripherally, 
and with tentacles of a slightly darker ground colour, with nearly white 
protuberances on their oral aspect. 
Dimensions.— Height about 100-130 mm. (4—5 inches); diameter of corona 
(ze. disk + tentacles), 250mm. (10 inches); largest tentacles, 30 mm. + 6 mm. 
(14 in. + + in.) 
Habitat.—Surface of fringing reef, Mer. 
Very probably this is the species referred to by Saville-Kent as ConpyLactis, sp. 
(‘‘ The Naturalist in Australia,” 1893, p. 222, Pl. xxxix a., fig. on p. 222), which 
he found in Western Australia. 
At first I was inclined to connect this species with Phymanthus muscosus, but the 
former is one of the Stichodactyline, and has a diffuse endodermal sphincter, which 
is very different from the strongly circumscribed sphincter of the present species. 
M*Murrich has recently (1896, p. 184) discussed the genus Heteractis, and has 
shown that H. lucida, D. & M., is a Sagartid. I think Duchassaing and Michelotti 
were mistaken in placing their species in this genus, and M*Murrich equally so in 
following them. Until Ragactis pulchra is anatomically investigated, ‘‘ H.” lucida 
must remain without a genus. 
I cannot be sure that my species does not belong to the genus Heteractis, but 
Quoy and Gaimard make no mention of suckers, so I think it best to keep them 
distinct for the present. 
The possession of tentacles at the margin and towards the centre of the oral 
disk suggests that this species should be placed among the Stichodactylinz, but I 
cannot satisfy myself that more than one tentacle springs from a mesenterial 
chamber.
