PODOCORYNE CAllNEA. 349 



adnate chitinous tubes, but covered superficially by a naked layer of ccenosarc, constitutes one of 

 its most remarkable characters, a cluu-actcr, lioAvever, which it has in common with lli/dractinia. 



Sars believes that the hydroid described a short time previously by Philippi,* under the 

 name of Di/smorphosa conchicola, is identical with his Podocoryne carnea ; and the same view is 

 entertained by Krohn.' This may be true, liut, as already said, Philippi's description will just 

 as closely apply to IL/dracfniia:''

TROPHOSOME. — Hydrouhizal expansion forming a tliin layer, from whose free 

 surface minute blunt cliitinous spines project at intervals. Htdranths springing at 

 short distances from one another over the surface of the hyclrorhiza, and presenting 

 two different conditions of development; those destitute of gonophores attaining a 

 height of about two lines, and having usually about twelve tentacles, while those 

 which carry gonophores are about half the size of the former, and possess no more 

 than from four to six tentacles. 



GONOSOME. — Gonophores on very short peduncles, forming a verticillate cluster 

 at a little distance below the tentacles of the smaller hydranths ; medusa with the 

 outer surface of the umbrella dotted with scattered thread-cells, velum well developed ; 

 lips of manubrium narrow, each terminated by a little pencil-like cluster of stalked 

 thread -cells. 



Colour. — Hydranths varying from white to flesh colour, medusa with the aianubriuni and 

 bulbous bases of marginal tentacles brownish red. 

 Development of Gonosome. — j\Iay to August.
