Family Primnoidae. 
Genus Thouarella. 
i. Thouarella moseleyi Wright and Studer. 
For description see: J. VERSLUYS, Primnoiden der Siboga Exp., XHIa, 1906, p. 29, 3 figs. 
Stat. 258. Tual, Kei-islands. 1 Ex. 
A single specimen, considerably rubbed, 15 cm. long, with twigs mainly bilateral, agrees 
well with T. moseleyi , which Kukenthal referred to his new sub-genus Euthouarella (Gorgonaria 
1924, p. 294.) The polyps are in pairs; the circumopercular sclerites show gradually tapering 
points; those below show some radial ridges, and there are five in an abaxial row. 
Previously recorded from Kermadec Islands and Flores-sea, and by Versluys from Siboga 
Station 45. 
Family Gorgoniidae. 
Genus Pseudopterogorgia. 
1. Psetidopterogorgia pinnata (Nutting) = Lophogorgia pinnata Nutting.

Referred to Pterogorgia sibogce by BlELSCHOWSIvY, Revision Gorgon. 1918, p. 62. 
Referred to Pseudopterogorgia by KUKENTHAL, Gorgonaria (Das Tierreich) p. 357. 
Stat. 273. Jedan-island. 1 Ex. 
A small piece of branch, probably almost terminal, 5.7 cm. in length by 1 mm. in breadth, 
slightly flattened, of a white colour, with no protrusion of verrucae. The spicules are very uniform, 
colourless spindles girdled with warts, the two median whorls being usually most conspicuous. 
The following measurements were taken: 0.12x0.02mm.; 0.15 X 0.03 mm. 
Previously recorded from Station 273, Anchorage oft Pulu Jedan, East coast of Aru 
Islands, 1 3 metres. 
Family Gorgonellidae. 
Genus Junceella. 
1. Junceella racemosa (Wright and Studer). 
For description see: SIMPSON, Revision of Gorgonellidae. Proc. Irish Acad. XXVIII, Section B, 
1910, p. 300, 4 figs. 
Stat. 166. 2°28 / .5S., I3i°3 / .3E. 118 M. Hard, coarse sand. 1 Ex. 
A fragment with two slender branches, the maximum length being 5 cm. It agrees with 
J. racemosa in its delicacy, in its thin ccenenchyma and thread-like axis, in the tendency of 
the polyps to occur in three rows, and entirely in its spiculation, which, however, tends to be 
very uniform in this genus. The general colour is brownish; many of the clubs are amber-yellow. 
Previously recorded from off Japan and Andamans, and by Nutting from Siboga Stations 
99, 164, 258, 260, and 310.
