228 On a nevj Genus and Species of Ilydroid Zoophyte. 



Claducoryne Jloccosa^ n. sp. 



Stem slender, generally simple or very sparingly branched, 

 often with a bend ; polypary of a light straw-colour, gene- 

 rally smooth, but sometimes very slightly and irregularly 

 annulated. 



Polypites generally separate, and ranged at irregular intervals 

 along the creeping filiform stolon ; long, linear, and very 

 slender, of a reddish-brown colour, merging at the base into 

 the colour of the stem ; the oral extremity of an opaque 

 white ; a silvery-white tubercle or boss of thread-cells l)e- 

 tween each tentacle in the anterior and in the posterior row. 



TentncJes very long and tapering, capitate, of two kinds — 

 simple and branched ; one row of simple capitate tentacles, 

 four to eight in number, immediately round the mouth, and 

 three or four rows of branched tentacles set in whorls round 

 the body, with three to four tentacles in each whorl, eacli 

 of the branched tentacles having from six to fifteen sliort 

 capitate ramuli set in somewliat irregular whorls round the 

 tentacles, and terminating in three of the capitate ramuli of 

 nearly equal length. 



(lonophores not known. 



Height from a ^ to ^ an inch. 



The form and size of the tentacles are the most prominent 

 points in Cfloccosax the branched tentacles are all long, and 

 increase in length up to the middle whorl, and then diminisli 

 in length towards the oral whorl, those in the middle whorl 

 being as long as the body of tlie polypite ; the tentacles are 

 ]jellucid, and taper gradually from the base ; the ramuli are 

 similar in appearance to the tentacles of Coryne vaginata. 



The stem is rarely and sparingly branched. 



The pearly bosses of thread-cells add considerably to the 

 beauty of this zoophyte. 



The polypites are generally separate, and rise at irregular 

 intervals from the stolon, thus presenting a very different a])- 

 pearance from the long and branched tufts of Coryne and 

 Syncoryne. The ramuli on the tentacles are pellucid, and 

 give a fleecy aspect to the zoophyte as it is waved to and fro 

 in the tide. 



Ilah. On stones at low tide at Herm, near Guernsey. 



The Rev. T. Hincks, who has kindly corrected the above 

 description, tells me that this species has "barbed thread-cells, 

 very much resembling those of llydra^'' and that he has met 

 with a single specimen of C floccosa among a quantity of 

 Gulf-weed.
