Acanthogorgia hirsuta, Proc. Zool. Soc, 1851, Radiata, pi. 3. 

 fig. 2. 



Coral branched ; branches nearly on the same plane, separate. 

 Hab. Unknown. British Museum. 



This genus bears some relation to Primnoa, but the cell is armed 

 externally with rows of short, thin, and its mouth with a series of 

 delicate, elongated bristle-like spines, instead of the broad scale of 

 that genus. From all other genera of the family it is most distinct. 



The IMS. description of this very curious coral was accidentally 

 mislaid at the time at which it was read, and did not appear in the 

 printed Proceedings of the Society. It was figured, by an error of 

 the artist, for and under the name of Nidalia occidentalis in the Pro- 

 ceedings of the Society for 1851.

These two Grallarice are of smaller size and have shorter tarsi 

 than the typical members of the genus. The bill also is shorter, 

 broader, and more flattened, and furnished with many basal bristles. 

 Together with Lafresuaye's Grallaria nana, they seem to form a sub- 

 ordinate group pointing towards Conopophaga.
