244 ' ENDEAVOUR " SCIENTIFIC RESULTS. 



Hydroida, but not always with success. Of the more im- 

 portant papers which I have been unable to obtain, most 

 refer to northern species ; in one or two cases, however, 

 notably in that of Professor D'A. W. Thompson's Report on 

 the Hydroida of the ' Vega ' Expedition, all my efforts 

 to secure copies have failed, and I mention the circumstance 

 in case any of the species which I have described as new may 

 prove identical with any therein described. A list of the 

 literature to which reference is made will be found at the 

 end of this Report.
