Thus we see that in the Greenland form, the longest ray in the first 

 dorsal fin goes from 5 to 7.0 times into the total length (to the hase of 

 the caudal fin), and in the European form from 6.2 to 7.3 times; conse- 

 quently no variety, and still less a species, can be based upon this pro- 

 portion. Nor does the height of the second dorsal fin constitute a 

 i-haraeter for separation, although it seems on an average to be a little 

 lower in the European than in the Greenland form, the longest ray in 

 the second dorsal tin in the latter being of a length that is contained 

 from i.9 to ~>.s times in the total length (to the base of the caudal tin), 

 while in the European form it is from 5.1 to 6.4 times. 



Taking everything into consideration, I think the idea of separating 

 the arctic sea-scorpion from that of the temperate regions as a definite 

 .-ubspecii-s. must be abandoned.
