270 CORYNE C^SPES. 



Colour. — Hydrocaulus light brownish yellow ; hydraiith Ijrownish red ; gonophores pale red. 



Development of Gonosome. — July. 



Habitat. — On sea-weeds. 



Bathymetncal Distribution. — Literal zone. 



Locality. — Coast of Norway (Sars). 



It was upon the present species that Sars, in the year 1S29, founded his genus Stijinla, with 

 the intention of removing to it the true Corynes which had, at the time when Sars proposed his 

 reform of the genus Coryne, been mixed up with Clava. We have already giveu the reasons 

 which render necessary the rejection of the nomenclature thus introduced by the celebrated 

 Norwegian zoologist.^ 



I have never met with the Coryne ramosa. It is described by Sars as occurring in great 

 abundance in the neighbourhood of Bexen, where it grows close to the surface of the water, on 

 a sea-weed which he names Facus nutans. Its taller growth and more elongated hydranths would 

 seem to distinguish it from Coryne 2}usillu, though I cannot regard its distinctness from this 

 species so fully established as to remove all doubts as to its validity as a separate species, while it 

 is distinguished from Coryne vayinata, not only by the absence of a sheath-like extension of its 

 perisarc, but by its more irregular ramification. 



*-...* 6. Coryne c.espes, Allinan. 



TROPHOSOME. — Hyduocaulus scarcely exceeding a quarter of an inch in height, 

 unbranched, or occasionally with one or two simple branches ; irregularly annulated, 

 the stems all closely crowded upon a hydrorhiza, which is formed by a creeping 

 entangled mass of tortuous tubes. Hydrantii elongated with about twenty-five 

 tentacles. 



GONOSOME.— Sporosacs globular, scattered on the lower portion of the hydranth, 

 where they spring by short peduncles from the axils of the tentacles. 



Colour. — Hydranths and spadix pale flesh-colour, perisarc reddish-brown. 

 Development of Gonosome. — March. 



Habitat. — Spreading over the surface of submerged rocks. 



Bathjmetrieal distribution.— V^^gion of the Cystoscira. About two feet below the surface of 

 the sea at low water. 



Locality. — Gulf of Spezia. 



Coryne caspes forms a dense moss-like growth, which spreads like a close turf over the 

 surface of submerged rocks, for many square miles in extent. It is a well-marked species ; its 

 short and, for the most part, simple stems, and its dense, crowded, moss-like growth, easily dis- 

 tinguish it from all the described species.
