Paita by R. E. Coker. The species was not secured by the Mission. 

 It is most easily separated from its Atlantic congener, H. vivanus, by 

 the lower lateral line, which does not run nearly as close to the back. 

 In H. vivanus there are only two complete rows of scales between the 

 lateral line and the beginning of the soft part of dorsal, and only four 

 below the base of the last ray, whereas H. peruanus has, respectively, 

 six and five complete row^s. 



Range. — Reported from the Gulf of California, from a depth of 58 

 fathoms, and from Peru and Chile. 



Genus PINGUILABRUM, new name "» 



Body elongate, compressed; mouth rather small; premaxillaries 

 protractile; lips thick; maxillary without a supplemental bone; teeth 

 in jaws in broad bands, the outer row in each jaw much enlarged, a 

 small patch on vomer, none on palatines ; margin of preopercle weakly 

 denticulate, covered by skin; opercle with 2 flat spines; gill rakers 

 short, rather few; branchiostegals 6; lateral line complete, not ex- 

 tending on caudal fin; scales moderately small, mostly ctenoid; dorsal 

 long, continuous, with 16 spines and 16 soft rays; anal with 3 spines 

 and 13 soft rays; caudal truncate; ventral inserted slightly behind 

 pectoral, close together; pectoral rounded. 



A single species is known.

Body elongate, fairly compressed, its greatest thickness only about 

 half its depth; back rather high, descending gently posterior to origin 

 of dorsal; dorsal profile anteriorly rather steep, nearly straight; caudal 

 peduncle very deep, 2.0 in head; snout long, rather blunt, 2.5; eye

 margin of eye, 2.7 in head; teeth in jaws in rather broad bands, the 

 outer ones much enlarged, conical, very small teeth on vomer, none on 

 palatines or tongue; vertical margin of preopercle minutely serrate, 

 the serrae hidden under the skin, the margin at and in advance of 

 angle without serrae; gill rakers short, none more than half length of 



i3» After these pages had been set up in galley proof Paul H. Oehser, editor of the U. S. National Museum, 

 called the author's attention to the fact that the generic name Epelytes is preoccupied in insects. Accord- 

 ingly, Pinguilabrum has been substituted. This name was suggested by the thick or fat lips of the type 

 species.
