BRITISH ZOOPHYTES. 49 



6. C. NUTANS (?), Allman. 



Hab. : Earraforth Caves, Shetland {A.M.N.) . Height 



A in 



in. 



This is the name given provisionally by Prof. Allman 

 to some specimens obtained by Mr. Norman, and pre- 

 served in spirits, which did not show the reproductive 

 organs {Allman, G. H., 271). 



Genus II. Syncoryne, Ehrenberg {in part). 

 Stem, polyjnte, and tentacles as Coryne. Gonophores 

 borne on the body of the polypite, and containing 

 medusiform zooids, having (at the time of liberation) a 

 bell-shaped or globular umbrella and four marginal 

 tentacles springing from ocellated bulbs.— T. H. 



The distinction between this genus and the preceding 

 is, therefore, that this genus is reproduced by me- 

 dusiform gonozooids. The differences between the 

 gonozooids of the different species at the time of 

 liberation are very slight. 

 1. S. EXIMIA, All. 



Coryne eximia {All, McA.), C. Listerii {Aid.). 

 Hab. : Along the north-eastern coast, where it is 

 the common species of the genus. Height 3 to 4 in. 

 Stems straw-coloured and transparent, smooth, except 

 just above the points of branching, where the branches 

 are ringed ; branchlets mostly developed on one side 

 of the branch. The polypites are pale pink, with 20—30 

 tentacles scattered, except 4 at the distal end. 

 2. S. Saesii, Leven. 



S. ramosa {Loven), S. Lovenii {8ars),'<' Coryne 

 Sarsii {McA.). 



* Prof. Allman treats this as a separate species, not included 

 amongst the British fauna (G. H., 276),
