OF THE TEMPEKATE ATLANTIC AND ARCTIC OCEANS. 201 



As regards the table of distribution (pp. 199, 200) it may be stated that: — 



1. The term '' British Area " will be found defined in my paper " The 

 British Area in Marine Zoology" (Ann. & Mag. Nat. Hist. ser. 6, vol. v. 

 1890, p. .345). 



2. A separate column has been assigned to the Faroe Channel, because 

 several British Government vessels have dredged there. The Faroe Channel 

 really geographically should fall under column 8. It is separated from 

 the British Area by the " Wy ville Thomson Ridge,'' south of which 

 the water is entirely influenced by the Gulf- Stream, with a bottom tem- 

 perature at 500 fathoms of 46° Fahr., while in the Faroe Channel the 

 water belongs to the Arctic Ocean, and has a temperature at 500 fathoms 

 at and below freezing-point ; for the Gulf-Stream meeting and passing 

 over the Wyville Thomson Rfdge affects the upper waters, but has no 

 influence on those at greater depths. 



There are some described forms which I am unable to identify, and a list 

 of these is given after the account of the known forms. At the end I give 

 a catalogue of the chief works and papers which relate to the nomenclature 

 of the class.

The number of spines at the base of the propodos is subject to considerable 

 variation, ranging from two to six ; the former number (as figured by Hoek)
