370 DR MURRAY ON THE DEEP AND SHALLOW- WATER MARINE FAUNA 



(272), 9 unnamed species, 6 varieties, and 2 species of which we have no information, 

 leaving 255 distinct fully-described species, the distribution of which may be discussed 

 in detail. 



These 255 species naturally fall into two divisions, viz., those that are known only 

 from the region represented by these eight Stations, and those that are known from other 

 regions of the ocean. 



a. Species limited to the area under consideration. 



In the first place, we find that there are 164 species (or 60 per cent, of the total 

 number of species and varieties found at these eight Stations) which, as far as we know 

 up to the present time, are limited to the region represented by these eight Stations. 

 These 164 species are distinguished by an asterisk in the list, and very little can be said 

 about them beyond the fact that they are known only from this area and from depths 

 over 1260 fathoms. 



LIST I h. 



We may here, however, enumerate those species found at more than one of these 

 Stations, indicating in brackets the number of Stations at which each species was found. 

 It will be observed that here again the species limited to this area do not show a wide 

 distribution within the area itself, for out of the 28 species occurring at more than one 

 Station, 24 species were each taken at two Stations, 3 species were each taken at three 

 Stations, and 1 species was taken at five Stations.

b. Species extending outside the area under consideration. 



We come now to consider those species which have a wider distribution and extend 

 into other regions of the ocean outside the area represented by these eight Stations. The 

 number of such species is 91 (or 33 per cent, of the total number of species and varieties
