The Siboga material of this species came from about the same locality as the type 
specimens; but, unfortunately, Mttne Epwarps does not give the depth at which his specimens 
were found. The peculiarities of this species are its robust growth, the large size of the cyclo- 
systems, the large broad lid, which completely covers the cyclocystem and the long but shallow 
septa. The ampullae, which are not mentioned by Mitne Epwarps, occur as swellings at the 
base of the lid. The cavity of the ampulla does not extend beneath the cyclosystem. 
It does not seem to us that MoseLey’s C. fwdca is the same species as the one described 
by Mirne Epwarps. The shape of the cyclosystems and their relation to the stem that bears 
them is different. In Mosetey’s specimens the cyclosystems are not raised above the surface of 
the coral or isolated from it, though the branches swell locally where they are situated. In Minne 
Epwarps’ specimens the cyclosystems are stalked and the septa do not quite extend to the 
edge. The lids are also different, being much: smaller. The proportions of the lids are not the 
same, they are not so broad in MoseEey’s specimens. In Mosetey’s specimens also the female 
ampullae occur on either side of the cyclosystems, while in our specimens, which are evidently 
identical with those of Mitne Epwarps they occur as swellings at the base of the lid. It appears 
to us therefore that MoseELry’s specimens do not belong to the same species as those described by 
Mitneé Epwarps and we propose to constitute a new species for them called Cryptohelia moseleye. 
2. Cryptohelia ramosa sp. n. Plate Il, fig. 22 and 23. 
Stat. 122. 1°58'.5 N., 125°0.5 E. N.E. of Celebes. 1165—1264 M. 4 fragments of one colony. 
This species forms a large and many branched flabellum with a height and breadth of 
about 75 mm. The branches do not anastomose. The base of the main stem is 3 mm. in 
diameter; the axis at the base of the terminal branches about 1 mm. The corallum is of a 
yellowish white colour. When calcined the usual longitudinal striations, into which the coenenchym 
canals open are more clearly visible, the whole surface is also seen to be granulated, owing to 
the presence of minute spines which are arranged more or less in transverse rows, giving a 
slightly rough appearance. The cyclosystems, which are oval, with a long diameter of 1,6 mm.
