48 NATURAL HISTORY OF 



structure of the coenosarc. Polypite fusiform, tapering 

 towards the neck and mouth ; colour white, with a 

 centre of reddish-brown. Tentacles 15 — 30, tipped 

 with red or rose colour, and arranged in 4 or 5 some- 

 what indistinct whorls. They are mobile, but when at 

 rest are either at right angles to the body or curved 

 inwards. Ova large. 



Mr. Gosse (Dev. Coast) describes the polypite every 

 graphically, and states that he has seen as many 

 as 25 ova expelled from one gonophore in a minute. 

 The ova exhibited amoeboid movements after expul- 

 sion. 



3. C. VERMICULARIS, T. H. 



Hab. : Shetland, in deep sea zone (T. H.). Height 

 I in. Polypite large worm-like, and growing in 

 shrubby tufts. Tentacles about 25, with large capitula, 

 arranged in whorls with considerable distances between 

 the rows. Stem only slightly ringed. 



4. C. FRUTICOSA, T. H. 



Hab.: Exmouth, Mounts Bay {T. H.); 'Kevvo., on funis 

 {Hodge). Height 1| in. Polypite delicate, growing 

 in dense bushes. Stems distinctly annulated and 

 more or less transparent. Tentacles 20. 



Prof. Allman is disposed to regard this as a variety 

 of G. pusilla. 



5. 0. Van Benedeni. 



Described by Van Beneden under the name of 

 Syncoryne pusilla. This is given by Mr. Hincks as 

 an English species upon the authority of a figure 

 drawn by Dr. Johnston from British specimens, but no 

 British habitat is kuown, and Prof. Allman treats 

 it as a foreign species under the name Actigonium 

 pusillum.
