676 ZOOPHYTES. 



caudate ; surface verrucose, the verruca? scattered, often bifarious, ob- 

 long ascending, subpyriform, incurved, cortex thin. 



Gorgonia myura, Lamarck, ii. 508, No. Gorgonia myitra, Lamour., Pol. flex., 420 ; 

 48. Encyc., 447. 



NOTE. Ehrenberg also refers to this genus the Gorgonia retellum. 



GENUS V.PRIMNOA. LAMOUROUX. 



Gorgonidce, axe inarticulate ; polypis contractis elongato-verruciformi- 

 bus et basi Jtectentibus, latere per squamas imbricatas armatis. 



Gorgonida? secreting an inarticulate axis ; polyps, when contracted, 

 long verruciform, and having motion at base; their sides armed 

 with imbricate scales. 



This genus was instituted by Lamouroux on the ground of the itn- 

 bricately squamous character of the verrucse. Ehrenberg united to 

 the species so called by Lamouroux, others less regularly imbricate, 

 which are here excluded, by adding as a characteristic the apparently 

 important peculiarity, that the verruca? admit of motion at base. They 

 are usually rerlexed upon the stem ; but Esper has figured a speci- 

 men in which they were erect. 



PRIMNOA LEPADIFERA. (Linnceus.) Lamouroux. 



P. laxe ramosa, dichotoma, subflabellata ; verruds elongatis (2|-3'"), 

 subpyriformibus, per valvulos octo clausis ; ramorum axe testaceo, ra- 

 mulorum corneo. 



Lax ramose, dichotomous, subflabellate ; verruca? long (2^ to 3 lines), 

 subpyriform, closed by 8 scales ; axis of the branches testaceous ; 

 of the branchlets corneous.
