The species may be defined; 
Hydrophytum subflabellate; nematophores on stem and septa; lid small, thin and narrow; 
edge of cyclosystem exsert and crenate; ampullae round, or on the two sides of the cyclosystem 
in the male, at the base of lid in the female. 
Conopora Moseley. 
MOSELEY. Chal. Zool. Vol. II, p. 97. 
The genus may be defined: 
Coenosteum arborescent, not flabelliform. Pores in regular cyclosystems only, their 
apertures turned in all directions; styles absent in gastropores and dactylopores; gastropore 
with two chambers upper and lower, which are separated by a circular opening. Gastrozooids 
and dactylozooids connected by a broad canal (fig. 35). 
Ampullae occur in the male as a slight swelling around the cyclosystems; very numerous 
gonophores in each ampulla. Female ampullae unknown. 
C. tenuis Moseley and C. major from this collection, are the only two species of the 
genus. The type specimen of the former occurred off the Kermadec Ils in 520 fms. (936 M.). 
The same species was found by the Siboga in 469 M. off New Guinea. The new species C. 
major was found a depths of 204 and 1go1 M. off Kei islands and N.E. Celebes.

The three colonies are all about 20 mm. in height. The cyclosystems are usually 0,8 mm. 
in diameter. The ampullae, which were not described by Moseery, occur in the male as slight 
swellings round the base of the cyclosystems. No female colonies were found. 
Colony not flabellate; 20 mm. in height; main stem stout, hollow, fistulose and coalescing, 
inhabited by a polychaet worm; cyclosystems 0,8 mm. in diameter, ampullae as swellings round 
the cyclosystems.

This species is closely allied to C. ¢enuzs, in the general method of growth, but is not 
so delicate as the latter. Tne height and breadth of the two most complete colonies are 
30 X 20 mm. and 35 x 15 mm. respectively. The hollow central stem, inhabited by a polychaet 
worm, is about 7 mm. in diameter near the base. The branches occasionally coalesce and 
arise irregularly from the surface of the main stem, though in one colony there is a slight 
indication of flabellate growth, owing to the branches being rather longer on two, opposite,
