THK collection of Alcyonaria does not present many very remarkable features. The 

 most interesting species is Centtoi*!* xpiaita, which forms an important connecting link 

 lictweon the groups of species formerly separated into the two genera Certitoisis and 

 Prhnnoisis. It is quite unlike any species that has hitherto been discovered. 



Primnoflla divergent is an important new discovery, as it exhibits many characters 

 of the genus Caligorgin, ami may be regarded as a connecting link l>etween the two 

 feoera. 



Clawdariti fntnklinuuut and Alcyonium paessleri were found by the ' Southern 

 Cross ' expedition off Franklin Island. It is a remarkable fact that not a single 

 specimen of either of these genera was obtained by the Scottish National Antarctic 

 Expedition. 



Tliouarella aiUnrctica, which was first obtained off the Falkland Islands, appears 

 to be a common species in the Southern Seas. 



The only species of Pennatulida found was Uinbellula carpeuteri, a species dis- 

 covered by the ' Challenger' expedition and hitherto found only in the South Polar 

 seas. Only one specimen was obtained, and this was unfortunately destroyed by fire 

 in my laboratory. 



The ' Scotia ' expedition obtained twenty specimens of UmMlida durittgima, but 

 not one other specimen of the Pennatulida.

Localities 1. W.Q., March 21, 1902, 30 yards from ship on Port Quarter. 8 fms. 

 2. W.Q., Much 21, 1902. 10 fathoms. 

 3. W.Q., March 18, 1902. 10 fathoms. 

 4. W.Q., June 15, 1902. 12j fathoms. 



There are many specimens of this species attached to stones, worm tubes and other 

 foreign objects. I have little doubt they belong to the same species as those described
