The remaining tentacles in the present form, "svhicli are ex- 

 tremely numerous, are slender, and have small capitula ; they 

 are scattered over the body, and extend to within a very short 

 distance of the base of it. 



In its pol}'])ite this genus has points of resemblance both to 

 Coryne and Clavatella, combining some of the characters of 

 each. By the total absence of a stem clothed with a polypary, 

 it is separated from all the rest of the Corynid<E. In this re- 

 spect Clavafella comes nearest to it. 



Unfortunately I have not had the opportunity of examining 

 the gonozooid. No trace of reproductive bodies appeared 

 among a large colony which I succeeded in keeping alive and 

 in perfect health for about three weeks.

Polypites very minute, slender, enlarging slightly upwards ; 

 proboscis opake white, the central part of the body reddish ; 

 tentacles about foi-ty (or more), a wreath of eight, with 

 rather stout stems and large capitula, encircling the oral 

 extremity, the rest irregularly distributed, slender, and with 

 smaller capitula, extending over more than three-fourths of 

 the body. Gonozooid unknown. 



This is an exquisite species. The poljrpites are extremely 

 minute, not more, I should think, than one-sixth of an inch in 

 height ; some Clavafelkc, whicli were kept in the same vessel 

 with the Gymnocoryne^ appeared like giants beside it. The 

 verticil of oral tentacles encircles the conspicuous opake-white 

 proboscis like a crown ; it is usually composed of eight ; but 

 nine are met with occasionally. The other tentacles are scat- 

 tered over the body, but with the tendency towards a verticil- 

 late arrangement which prevails more or less amongst the 

 Corym'dxe ; they are very slender, and surmounted by small 

 capitula, and decrease very markedly in size towards the base 

 of the polypite. The endoderm is laden with reddish granules, 

 which show through the transparent ectoderm ; the colour is 

 most vivid on the upper part ot the body, and becomes fainter 

 below. The polypites are extensile, and become very slender 

 when fully elongated.
