DEEP-SEA FISHES OF THE ATLANTIC BASIN. 



(10) Radial formula. — In the dorsal this ranges from 102 to 120; in the anal from 87 to 

 100. There is no apparent relation between the number of rays and the relative propor- 

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

 panied by a relatively large number in the anal. 



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

 equal. 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 31° and 

 45° F. 



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

 103), under the name of Pleuroneetes cynoglossus, and subsequently named by him Pleura 

 nectes pinguis (Afhandling, Kougel. Danske Videnskabernes Selskabs, Naturvid. og Math., 

 Copenhagen, vol. 1, 1821, p. 15), is probably identical with this species. The true relations 

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

 Sci. Phila., 1801, p. 218), as well as the curious misapprehension by which the synonymy of 

 P. pinguis and the halibut has been confounded.
