6. Kyphosus elegans * (Peters. ) (No. 39635, U. S. N. M. ) 



Head 3.5 iu length of body to base of the caudal ; depth 2 in length 

 of body; dorsal tin, XI— 14 ; anal, III— 13; scales, 12-70-22. 



Body elliptical, compressed, head short, snout very blunt, eye moderate, 

 3.5 in head, mouth small, nearly horizontal, the maxillary barely reach- 

 ing the front margin of the eye, both jaws with a single close-set row of 

 incisors, obtusely lanceolate, transparent on the extremities, most of 

 the teeth with a dark spot in the middle of the body of each, teeth with 

 conspicuous roots posteriorly, behind which there is no band of teeth ; 

 fine teeth on the vomer, palatines, and tongue. 



Gill-rakers on anterior arch not long, the longest about one-half the 

 diameter of the eye, slender, about 14 developed on the lower limb, 

 those on the succeeding arches short, not well developed. Preopercle 

 obsoletely serrate at and near the angle iu the older specimens, not 

 evidently serrate in the younger specimens; remaining parts of the 

 limb entire. Preorbital covering but little of the maxillary. Squama- 

 tion complete, all parts of the body and head being scaled, except a 

 small space just above the snout, the preorbital region, the premaxil- 

 laiy, and tip of lower jaw. The scales on the head come far down, well 

 in front of the anterior margin of the eyes, the maxillary well scaled; 

 scales small, ctenoid, somewhat crowded anteriorly, about 70 in the lougi- 



" We have substituted the name elegans for the new name, chopa, proposed by us, as 

 it is highly probable that our species 18 identical with Pimeleplerus elegans Peters (Ber- 

 liner Monatsheriehte, 1869), from Mazatlan. We are indebted to Dr. F. Hilgendorf 

 for the following notes on Peters' types, received while this paper is in type: "Schnp- 

 pen iiln t L. 1. zahle ich 64-66 nnd ausserdem etwa 10 kleinere auf den Schwanzflosse. 

 Die Hohe des ersten weichen Strahles der Analis betriigt 38 mm . Die Basis- 

 Lange der ganzen Flosse ist 68»»V The original description applies equally well to 

 K. anulogus and to our species.
