162 ANNALS OF SCOTTISH NATURAL HISTORY 



Those measurements show that the Scottish specimen differs 

 from the type specimen, measurements of which are given by 

 Billard (1909), and from the Gough Island specimen, which I have 

 described, in having hydrothecae smaller in all dimensions than 

 theirs. 



Locality. CLYDE SEA AREA BARRIER PLATEAU between Sanda 

 Is. and Ailsa Craig, 24 fms. 



The valuable investigations of Dr. A. Billard have shown that 

 the species described by Bale as Campanularia trident ata is 

 identical with Laomedea simplex of Lamouroux, the locality of 

 which is indeterminable. The only records of which I am aware 

 are: Port Phillip in the south of Australia (Bale, 1894); French 

 Pass, north of South Island, New Zealand (Hartlaub, 1901) ; Gough 

 Island, midway between Cape of Good Hope and Cape Horn 

 (recorded by me in 1907 from the collections made by the Scottish 

 Antarctic Expedition), and the present record, which adds the 

 species to the fauna of the North Atlantic.
