family for a form so closely related to a well known genus would 

 be clearly inconvenient. I have re-examined the type specimen 

 of Chrysogorgia constricta (Hiles), and I am convinced that its 

 affinities with the genus Chrysogorgia as defined by Wright and 

 Studer are pronounced. In neither case is there sufficient justi- 

 fication for the estabhshment of a new family. The specimen 

 from which Miss Hiles described her new species was fragment- 

 ary, and the question whether a new genus should be constituted 

 for it may be postponed until complete specimens are forth- 

 coming. 



Trichogorgia Flexilis N. gen et spec. 

 Plate VIII., fig. 13. Plate IX., figs. 16 and 17. 

 Locality : Off Cape Recife, 34° 7' S., 25° 43' E. 56 fathoms. 



This species was obtained not very far from the station where 

 Malacogorgia capensis was found but in deeper water. The 

 colony is attached by a short main unbranched stem 8 mm. long, 

 2 mm. in diameter, expanding into an irregular disc 6 mm. in 

 greatest diameter. Branching begins by a long but narrow 

 branch 8 mm. from the base, and this is soon followed by what 

 appears to be dichotomy, and then a third branch is given off 

 at a considerable distance from the right hand division of this 

 dichotomy, and finally a fourth.

If we consider that, in the position in which the specimen is 

 drawn, the branch to the right is in all cases the main axis, then
