DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



(10) Rndial formula. — In tlie dorsiil this ranges from 1013 to 120; in the anal from 87 to 

 100. There is no apparent relation between the nnmber of rays and the relati\ e propor- 

 tions of height and length of body. A large number of rays in the dorsal is usually accom- 

 panied by a relati\'ely large number in the anal. 



(11) Transpcrso rows of scales. — Tlieir number above and below the lateral line is nearly 

 ecpial. The range is about from 10 to 50. There appears to be no relation of number of 

 transverse rows to comparative height of body. 



The thermal range of the species appears to be defined nearly by the limits 34^ and 

 45° F. 



Dr. Giinther suggests that the fish first cited by Fabricius (Fauna rocnlandlca, p. 

 163), under the name of Pleuroncctes eynoglossus, and subsequentlj' named by him Pleuro- 

 ncctes puKjids (Afhaiidling, Kongel. Danske Videnskabernes Selskabs, Naturvid. og Math., 

 Copenhagen, vol. i, 1824, p. 45), is probably identical with this species. The true relatious 

 of the Greenland fish have already been pointed out by Professor (jill (Proc. Acad. Nat. 

 Sci. Phila., 1804, p. 218), as well as the curious misapprehension by which the synonymy of 

 F.pinguis and the halibut has been confounded.
