LARID^E.

GrONozooiD. UMBRELLA (at. the time of liberation) 

 rather deeply campanulate ; MANUBRIUM short, of a pale 

 green colour; RADIATING CANALS terminating in con- 

 spicuous orange bulbs, each bearing two granulated 

 tentacles, with a deep-red ocellus at the base. 



Height of the polypites i to i inch. 



THE polypite of this species presents all the characters of 

 Podocoryne. The reproductive zooid is identical at the 

 time of detachment with that of the genus Bougainvillia, 

 which ranks amongst the Eudendriidae. 



It is probable that it follows the same course of deve- 

 lopment, and exhibits, when mature, the branched oral 

 appendages and the marginal clusters of tentacles that 

 belong to the latter in its adult state. But the later 

 stages of its growth have not been observed.

POLYPITES with a very small number of filiform tentacula,
