The only specimen of this widely distributed species that was dredged by the Siboga, 

 is 50 mm. in height; the base of it was broken off, but apparently not far from the base of 

 attachment. The width of the colony is about 25 mm., the diameter of the main stem 5 mm. 

 and many of the short abruptly ending branches as much as 3,5 mm. Most of the cyclosystems 

 are large and prominent, being from 1,6 • 0,8 mm. to 1 x 0,8 mm. They are formed by 

 alternate gemmation (though this is sometimes rather irregular), but owing to the great growth 

 of the coenenchym they are displaced in such a way that, on old branches they occur more 

 or less irregularly, in two rows, on one surface, which may therefore be called "anterior", and 

 rarely or spasmodically on the other, the "posterior" surface. The colour is a pale yellowish pink.

The largest complete specimen, was 40 mm. in height, 35 mm. in breadth. The cyclo- 

 systems are from 1,5 X 0,7 mm. to 0,8 X 0,6 mm. in diameter. 



The Siboga specimens have been compared with the type specimen in the British Museum 

 from the Cape of Good Hope and they prove to be identical. Unfortunately Saville Kent does 

 not give the depth at which his material was found. This species is in superficial characters 

 curiously like the genus Conopora, the coenosteum being both fistulose and coalescent, and 

 neither are flabellate in growth. A polychaet worm was found in the cavity of the main stem 

 and as mentioned above was probably responsible for its peculiar formation. Conopora differs 

 ho wever from this and all the species of Sty laster in the absence of styles from both gastro - 

 pores and dactylopores.

A small dry specimen has very much the same characters as those described and figured 

 by Lindström for his species Cryptohelia virginis from the West Indies. We agree with Moselev 

 in considering that the species should be placed in the genus Stylaster, as it differs markedly
