THE SHORE FISHES OF PERU 381 



papillae consisting of a series across chin, and a row extending from 

 lower lip to posterior margin of preopercle; scales ctenoid, extending 

 slightly on base of caudal, and forward nearly to interorbital ; dorsal 

 fins well separated, the fourth spine longest, 1.9 in head; second dorsal 

 notably longer and higher than the first; caudal round, a little shorter 

 than head; anal short, the last ray longest, origin of fin slightly behind 

 that of second dorsal, its base 1.4 in head; ventral disk large, its long- 

 est rays 1.4 in head; pectoral large, reaching well beyond ventral disk 

 but not quite to origin of anal, 1.2 in head. 



Color dark brown above, paler underneath; back and sides with 

 dark cross bars, these most distinct laterally; head nearly uniform 

 dark brown above, with a small black spot behind eye; vertical fins 

 dusky; ventral disk and pectoral light, the latter with indefinite dark 

 cross lines. 



A specimen, 117 mm. (92 mm. to base of caudal) long, secured at 

 La Lagunilla by the Mission, forms the basis for the foregoing descrip- 

 tion. The four specimens collected at Lobos de Afuera by R. E. 

 Coker, and described by Evermann and Radcliffe (see reference above), 

 were not seen by me. This species evidentally is not abundant on the 

 coast of Peru. 



Range. — "Known from all warm seas" (Meek and Hildebrand, 1928, 

 p. 868). 



Family GOBIOIDIDAE 



Body greatly elongate, compressed; head rather low and long; eye 

 small or rudimentary; mouth large, oblique; lower jaw projecting; 

 no barbels; teeth in jaws in one or two series; gills 3%; scales present 

 at least on posterior part of body; dorsal fin single, continuous, 

 anteriorly with flexible spines; caudal joined to the dorsal and anal; 

 ventral fins united, forming a disk. 



A single genus is known from Peru. 



• Genus GOBIOIDES Lacepede, 1800 



Teeth in the jaws m two series, those of the outer series enlarged; 

 scales covering body, more or less embedded, becoming smaller for- 

 ward; dorsal with about 6 to 8 spines, and 14 to 16 soft rays; anal 

 with 1 spine, and about 14 to 16 soft rays; caudal long, pointed. 

 Other characters are included in the description of the family. 



One species is known from Peru.
