FISHES OF WEST COAST OF PERU. 25 



mouth 1.6 ; P. 2.5 ; maxillary teeth pointed, biserial, recurved, fixed ; 

 vomerine teeth uniserial, the three anterior teeth stronger than the 

 others. 



Color in life, olivaceous with large dark spots; the spots on head 

 small (about the size of eye or smaller) and^set closely. In spirits, 

 the ground color is a very light brown; a row of black spots along 

 median line of back; some of these circular, crossing dorsal fin, 

 equal on each side of median line ; others hemispherical and appear 

 only on one side of median line; others appear as if the two hemi- 

 spheres of a circle had been partially crowded by one another until 

 they fail to m_atch, the amount of variation being very great ; below 

 these and alternating with them is a row of larger black circles, each 

 of these tending to pair with its fellow on the opposite side and 

 extending below lateral line, in some cases appearing like a broad 

 vertical crossband on back ; slightly below the plane of this series and 

 alternating with the spots composing it is a third series, smaller than 

 the second and similar in position to the first, not continuing beyond 

 anterior half of tail but replaced on posterior half of tail by a series 

 of spots on the ventral surface, crossing the anal, similar to the 

 first row on median line of back; head dotted with small black cir- 

 cular areas, smaller than those on body; interspaces on dorsal he- 

 tween black areas, body color; anal blackish; pectoral body color 

 with three blackish areas.
