Dana describes this species, of which the habitat was unknown, as of a brownish 

 colour ; the only species in the Challenger collection was, when first examined, of a pale 

 blue tint, which has bleached to a nearly perfect white in the spirit. It seems, however, 

 to approach very closely to Dana's species, and as such we venture to record it. 



Habitat. — Amboina ; shallow water. 



Family V. Tubiporid^.

Some fragments of this species, which is not uncommon in the shallow waters of the 

 tropical seas, were met with in some coral debris from Samboangan. 



This species was also found at Santa Cruz, Major Island, opposite Samboangan ; 

 living specimens were dredged from a depth of 1 fathoms ; the beach was covered with 

 " cart-loads of the dead and dried coral." *

Within this family, as defined by the authors above quoted, we include those polj'p 

 colonies in which the individuals are united either by stolons or by a basal membrane, 

 so as to form incrustations over foreign objects ; or in which they develop into bush-like
