nearly tbree-fourtlis of the width of the head at the periieudicalar pass- 

 ing through their centers. 



The dorsal fin begins over the posterior part of the pupil of the up^jer 

 eye. Its rays are long, widely separated, and with their tips i)rotrudiug 

 beyond the membrane, giving to this, as also to the anal, a ragged, 

 irregular appearance. Its greatest height (8) is equal to half the length 

 of the head. The anal is inserted under the axil of the pectoral, and its 

 height is about the same as that of the dorsal. 



The length of the caudal (20) is equal to one-fifth of that of the body, 

 without including caudal. It is broad, fan-shaped, acutely convex in 

 outline. The distance of the ventral from the snout (28) is about one- 

 third the length of the base of the dorsal. The arrangement of these 

 fins upon the ventral keel is much as in Limanda ferru(jinea, the right 

 fin being almost upon the median line. The pectorals are normal. 



The color is grayish brown, mottled with darker patclies. There is a 

 consi)icuous black blotch uijon the outer rays of the caudal on either 

 side. 



Eadial formula : D. G4 ; A. 63 ; C. 18; P. 7 ; V. G; lateral line about 88. 



This species is dedicated to my associate Dr. Tarleton H. Beau, of the 

 United States National Museum.
