30 DR. J. E. GRAY ON A NEW GENUS OF POLYPI. [Feb. 11, 



MORCHELLANA. 



The coral subclavate, coriaceous, subcalcareous, and loosely cellular 

 within ; the stem subcylindrical, elongate, hard, coriaceous, and mi- 

 nutely granular on the surface. 



The head formed of numerous, irregularly dispersed, short-lobed 

 prominences, which are covered at the end with diverging conical 

 prominent polype-cells, — the lobes and cells being strengthened with 

 superficial fusiform spicules, slightly covered with the skin of the 

 coral ; the polypes entirely retractile.
