THE SHORE FISHES OF PERU 391 



orbital tentacle divided into three parts nearly to base, each part 

 fringed, the first highest in females, the first and second of equal 

 length in males, very long, 1.5 to 2.5 times length of eye; gill opening 

 not extending to base of lowermost pectoral ray; lateral line ending 

 well in advance of midlength of body; dorsal beginning at vertical 

 from margin of preopercle, the fourth spine highest, higher in males 

 than in females, less than two in head in males, exactly two in females; 

 soft part of dorsal marked by a moderately deep notch; caudal fre^ 

 from dorsal and anal, or occasionally attached by membrane to the 

 dorsal, its margin convex, about two-thirds length of head; seventh 

 or eighth ray of pectoral longest, reaching origin of anal. 



Color light grayish yellow, with dark-brown marblings; a large 

 brown spot, with a sky-blue speck in anterior part, behind eye; three 

 or four dark bands on side of head below eye; an indigo-brown spot be- 

 tween the first three spines of dorsal in males. 



This species was not secured by the Mission, and as no specimens are 

 available to me the description offered was translated, rearranged, and 

 condensed from Steindachner's original account. 



Starks (see reference above), who reported two specimens from 

 Paita, the type locality, gave the dorsal rays as 15 and 17, and the 

 anal rays as 20 in each specimen. 



Range. — Known only from Paita, Peru.

Figure 75 



Head 3.3 to 3.5; depth 4.1 to 4.2; D. XII, 16 or 17; A. 20 or 21; 

 P. 14 or 15. 



Body moderately compressed, rather robust, its greatest thickness 

 about three-fourths its depth; head short, deep, its outline very steep 

 in front of eyes, then gently convex, without a cross groove behind 

 eyes; caudal peduncle strongly compressed, 3.1 to 3.5 in head; snout 

 very blunt, 3.4 to 4.3; eye 3.2 to 3.5; interorbital about 16 to 23; 

 mouth horizontal; lower jaw slightly included; maxillary reaching 

 below middle of eye 3.0 to 3.5 in head; teeth in each jaw in a single 

 close-set series, slightly compressed, no canines; lips not fringed; 

 anterior nostril with a low tube and a tentacle about as long as pupil; 

 tentacle on upper margin of eye about two-thirds length of eye, 

 simple, bifid or trifid ; gill opening notably broader than base of pec- 

 toral, extending below lowermost ray of pectoral; lateral line well 

 developed anteriorly, with a downward curve, and a few pores form- 

 ing a short straight section on middle of side, reaching beyond be- 

 ginning of soft part of dorsal ; dorsal fin beginning about over margin 

 of preopercle, moderately notched, the spines fairly slender, the longest 

 ones at about middle of spinous part, 2.5 to 2.8 in head; soft part of 

 dorsal about as long as spinous part, and higher, the longest rays 

 as long as postorbital part of head; caudal round, entirely free from
