Dorsal beginning above ami between the nostrils, the anterior rays 

 short, but with free tips; longest ray 2£ in head. Pectorals of eyed 

 side If to 2 in head, of blind side 2^ to 2i. Ventrals subequal, both 6- 

 rayed, 2| in head, extending one-third their length beyond vent. 



Color plain brown, unspotted. Fins dusky, thickly punctulate; young 

 with two large oval indistinct dark spots on dorsal and anal, three on 

 caudal, of which the middle is much larger. 



Numerous specimens, the largest about 8 inches in length, were 

 dredged in 7 fathoms at Station 2800, and in 1G fathoms at Station 2S02. 

 The closely related species, Azevia panamensis, was obtained at Station 

 2707. Azevia querna is probably the species obtained by Professor Gil- 

 bert at Mazatlau in 1882. (See Jordan & Goss, Review Pleitronectidw, 

 1889, p. 271.)

Body regularly elongate, elliptical, dorsal and ventral outlines equally 

 curved; orbital rim euteriug anterior profile, which is equally curved

 rather large, the maxillary reaching about to middle of pupil, 2£ to 2f 

 in head. Teeth equally developed on both sides, small and equal, uni- 

 serial. Snout 5 in head ; the premaxillary spine prominent. Inter- 

 orbital space a narrow, sharp, naked ridge; eyes large, the lower

 veloped, the last 2 much shorter.
