A single simply pinnate, unbranched, unfascicled colony, 11 mm. in 

 height, represents this species, which was originally described by Busk 

 under the name of Flnmidaria hrevirostris, from Cumberland Island, 

 Queensland. The minute characters of the hydrothecse agree with Bale's 

 recent diagnosis and figures, except that the constriction of the hydi'otheca 

 is much less abrupt than that shown, and in this respect the hydrotheca 

 approaches most closely the condition of that figured by Bori-adaile and 

 by Billaid. Such hydrothecae occur in the specimens from Murray 

 Island and from Fiji, but Bale has found that " in both cases the majority 

 are of the more abruptly bent type."

BemurJi.t. — An examination of Whitelegge's slide listed as " Halicor- 

 naria, sp. nov. ? " from Lord Howe Island shows it to be identical with 

 Thecocarpux brevirostrix (Busk). 



The range of this species must be extended to the Kermadecs as I 

 have recently examined a specimen from Denham Bay, Sunday Island, 

 Kermadec Islands.
