with similarly small and embedded scales; ventral of blind side and 

 pectoral of both sides without scales evident at the surface; caudal 

 covered with small scales on both sides nearly to posterior margin. 

 Gill rakers quite short, nine on lower limb of first gill arch, three on 

 upper limb with a tubercle above, the same number on both sides. 

 D. 80. A. 63. Pectoral rays 12 on both sides. Origin of dorsal a 

 little in advance of anterior margin of eye; base curving downward 

 anteriorly, to blind side ; anterior rays considerably shorter than those 

 over middle part of body; all rays simple, except last 10, the penul- 

 timate ray and the three next to it, in front, branching dichotomously 

 twice, the others branching but once. Origin of anal somewhat in 

 advance of base of pectoral; all rays simple except last 11. Ventrals 

 symmetrically placed, equal in length, the tip reaching to base of 

 second anal ray. Pectoral of eyed side a little longer than that of 

 opposite side, not reaching lateral line on either side. Caudal bicon- 

 cave. Maxillary extending backward somewhat past a vertical 

 through posterior margin of lower eye at a distance less than the 

 diameter of the pupil. Teeth in one row; anterior teeth of upper 

 jaw quite large, caninoid, lateral ones quite small; teeth of lower jaw 

 subequal, but slightly decreasing in size posteriorly, nearly as large 

 as anterior teeth of upper jaw. Mouth oblique, outline of gape some- 

 what curving; a horizontal line through distal edge of upper lip fall- 

 ing somewhat below upper edge of lower eyeball; lower jaw equal in 

 front with upper jaw, its anterior edge vertical; chin angular; artic- 

 ulation of mandible on a vertical behind posterior margin of eye. 

 Anterior and posterior margins of lower eye placed somewhat behind 

 those of upper. Anteriornostril with a comparatively short flap behind 

 and with a raised edge in front; posterior nostril somewhat larger, its 

 rim not raised. Preanal spine not evident on surface. Length of a 

 chord subtending the curve in the lateral line 3.2 in straight part to 

 end of hypoural, a vertical from a chord to apex of curve tlu'ee times 

 in chord. 



Measurements.'^ — Total length, 455. Standard length, 381. Depth, 

 168 (44.1) ; head (to end of scaled part, not including the soft border), 

 114 (29.9); maxillary, 58 (15.2); interorbital, 12 (3.2); pectoral of 

 eyed side, 47 (12.3); pectoral of blind side, 42.5 (11.2); caudal, 75

 (to upper eyeball) , 33.5 (8.8); eyeball, 17.5 (4.6). 



Color. — Eyed side quite dark, irregularly shaded. Some more or 

 less diffuse spots present, two or three very faintly suggesting ocelh. 

 Pectoral of eyed side with transverse rows of somewhat elongate 

 spots. Two diffuse curved bands on caudal, against an irregularly 

 shaded background. Lower side normally light colored, the vertical

 given part in millimeters; the number in parentheses is the percentage in the standard length.
