THE SHORE FISHES OF PERU 501 



A specimen 137 mm. (117 mm. to base of caudal) long, taken at 

 San Lorenzo Island, near Callao by fishermen, was furnished by the 

 Mission. This is the second specimen of this species to be reported, 

 the type (see reference to Regan above) having been taken at Lobos 

 de Tierra in 8 to 10 fathoms. 



Range. — Coast of Peru. 



Family ANTENNARIIDAE: Frogfishes 



Body somewhat elongate, more or less compressed; head short, 

 deeper than broad; mouth moderately large, nearly or quite vertical; 

 premaxillaries protractile; teeth small, pointed, in a narrow band in 

 each jaw, also usually at least present on vomer and palatines; gill 

 opening quite small, situated at or below "wrist" of pectoral; skin 

 naked, smooth, or prickly; first dorsal consisting of one to three 

 separate spines, the first usually bristlelike, generally if not always 

 provided with a membranous "bait" at tip; second dorsal notably 

 longer than anal; ventrals jugular, rather close together, with one 

 spine and five soft rays; pectoral rather large, with elongate carpal 

 bones, forming a "wrist" set more or less at right angles to rest of fin. 



A single genus comes within the scope of the present work. The 

 remarks concerning the angling characteristics of the Lophiidae apply 

 to this family also. 



Genus ANTENNARIUS Commerson, 1798 



Gill opening very small, situated just below base of wrist of pectoral; 

 skin rough, provided with granules or prickles, and usually with dermal 

 cirri; first dorsal spine with bait, slender, bristlelike, the second and 

 third strong; ventral much shorter than pectoral. 



A single species, new to the fauna of Peru, is reported herein.

 (original description). — Meek and Hildebrand, 1928, p. 1013, Panama Bay 

 (synonymy; description; range). 



Head measured to margin of opercle 2.6^®; depth 1.8; D. III-13; 

 A. 8; P. 13. 



Body rather short, compressed, its width just posterior to pectoral 

 fin a little greater than half the depth; caudal peduncle long, -slender, 



" Owing to the peculiar structure of the fish the proportions given are only approximately correct. The 

 margin of the opercle, which is not free, may be felt, if it cannot be seen,, underneath the skin.
