THE SHORE FISHES OF PERU 403 



Genus EMBLEMARIA Jordan and Gilbert, 1883 



Body rather long, compressed; head rather low, compressed, pointed 

 to rather blunt; mouth moderately large, the maxillary extending be- 

 yond posterior margin of eye; teeth in jaws consisting of a series of 

 strong outer teeth, followed anteriorly by a band of small pointed 

 teeth; vomer with a few minute, sometimes indefinite teeth; palatines 

 with a series of strong teeth; gill membranes united, and free from the 

 isthmus ; no lateral line ; no cirri at nape ; no scales ; dorsal fin long, with- 

 out a definite notch, the spines flexible. 



Three species come within the scope of this work, two of which 

 appear to be new. 



KEY TO THE SPECIES 



a. Spinous dorsal very high anteriorly, its longest rays about as long as head; 

 ventral fin long and broad, about as long as head; orbital tentacle simple, 

 much longer than eye; side with dark cross bars, separated by light lines. 



hudsoni (p. 403) 

 aa. Spinous dorsal much lower, its longest rays notably shorter than head; ven- 

 tral fin much smaller and narrower, notably shorter than head; side with 

 a series of dark spots, but without definite bars or light vertical lines. 

 b. One very small, simple orbital tentacle, scarcelj' as long as pupl; snout, 

 quite pointed; pectoral with 13 rays; dorsal fin anteriorly plaiin dusky 



without a conspicuous dark spot tortugae, new species (p. 404) 



bb. Two moderately large, fringed orbital tentacles, the anterior one the larger, 

 about as long as eye; snout rather blunt; pectoral with 14 rays; dorsal fin 

 not dusky anteriorly but with a conspicuous black spot between second 

 and third spines bicirrus, new species (p. 406) 



EMBLEMARIA HUDSONI Evermann and Radcliffe 



Trambollo 



Emblemaria hudsoni Evermann and Radcliffe, 1917, p. 147, pi. 13, fig. 2, 

 Sechura Bay, Peru (original description). 



Head 4.2 to 4.5; depth 5.8 to 6.4; D. XXI to XXIII, 14 to 16; A. II), 

 24 to 26; P. 13; vertebrae 40 (one specimen dissected). 



Body quite elongate, compressed, its greatest thickness about 

 half its depth; head moderately compressed, its dorsal outline ascend- 

 ing rather rapidly to interorbital ; caudal peduncle strongly com- 

 pressed, 2.75 to 3.1 in head; snout fairly blunt, with a deep median 

 groove above, extending to occiput, with a rough bony ridge on each 

 side, 4.5 to 5.6; eye 4.7 to 5.25; interorbital 12.5 to 15.7; mouth hori- 

 zontal, terminal; maxillary reacliing far beyond posterior margin of 

 eye, 1.8 to 2.1 in head; teeth in each jaw in an outer series of rather 

 strong, short, slightly compressed teeth, not extending to angle of 

 mouth, and followed anteriorly by a band of minute pointed teeth; 

 vomer without definite teeth; palatines with a series of teeth rather 

 stronger than the lateral ones in the jaws; both lips minutely fringed;
