in all specimens but 1 (89 to 109, instead of 109), this difference being 

 due to the greater development of the pores in the larger specimens, 

 in which small pores are occasionally placed between the larger ones. 

 The teeth are in two rows in both jaws; the outer row of the lower 

 jaw small, even, and close to the main row, so as easily to escape 

 notice. The anterior half of the premaxillaries with a single row of 

 sagittate canines; the posterior half with two rows of much smaller 

 teeth. 



Vertebrae 12 + 41 = 53 in A. evermanni; 12 + 37 = 49 in A. stomias 

 of the Alaskan fauna.

Subfamily PLEUBONECTIN"AE. 

 Genus POECILOPSETTA Gunther. 

 Poecilopsetta Gunther, Shore Fishes, Challenger, p. 48. 



POECILOPSETTA PLINTHUS (Jordan and Starks). 



Alaeops plinthus Jordan and Starks, Bull. U. S. Fish Comm., vol. 22, 1902 (1904), 

 p. 623, pi. 5, fig. 2. Suruga Bay; Owari Bay. 



Albatross station 4946, near Kagoshima, Kiusiu. 



Albatross stations 5071 and 5074, Suruga Gulf. 



The scales in this species are ctenoid with blunt, rounded spines, 

 as in Poecilopsetta Jiawaiiensis Gilbert. 



Lateral line absent on blind side in both species. 



The scales in P. Jiawaiiensis are smaller; the pores in the lateral 

 line 84 to 97. As this is the only important difference between the 

 two species, their relationship would probably be better expressed by 

 placing them in the same genus.
