156 CATALOGUE OF THE ZOOPHYTES OF 



consistency, in its dark brown colour, and in its not having the 

 septa visible even when dried. It answers tolerably well to the 

 description of Sarcocliitmn polyoum^ Hassall; and, therefore, in 

 the present nncertain state of the species, I have thought it best 

 to consider it such, rather than to introduce a new name. It 

 does not appear to differ generically from the other encrusting 

 Alcyonidia; but should it be considered necessary to divide these 

 from the branching kinds (most of which, however, are encrust- 

 ing in their young state), the name of Sarcochitum might be 

 adopted for the group.
