NEW GENERA AND SPECIES OF FISHES FROM PUERTO RICO. 353 



is deeper, the eye larger, and the snout longer. It is very close to Sfolephorus gil- 

 berti Evermann & Marsh, differing chiefly in the larger eye, in the color of the 

 back, and the somewhat less sharply compressed bellj'. One specimen, the type 

 (No. 49360, U. S. N. M.), 4.5 inches long, collected at Puerto Real, January 27, 1899. 

 Named for Prof. Samuel Garmaii, of the Museum of Comparative Zoology. 



4. Prionodes baldwini Evermann & Marsh, new species. 



Head2.5; depth 3.2; eye 4; snout 4.6; maxillary 2.4; mandible 2; interorbital 7; 

 D. X, 12; A. Ill, 7; pectoral 1.4; ventral 1.3; caudal 1.7; scales 4-42-12. 



Body elongate, moderately compressed, not elevated, covered with ctenoid scales ; 

 dorsal and ventral outlines alike; head moderate, pointed, naked above and below; 

 eye large, greater than length of snout, high in position; mouth terminal, slightly 

 oblique, the maxillary reaching middle of eye or somewhat beyond; gillrakers 

 short, 6 developed on lower limb; teeth small, conical, and sharp, on vomer and 

 palatines and in several series in each jaw, with weak canines in front and a few 

 canine-like teeth on middle of side of lower jaw; cheek with about 7 rows of 

 scales; preopercle finely serrate; opercle ending in 3 sharp, flat spines, the middle 

 one largest, a membranous pointed fliip projecting beyond; fins all naked, the dorsal 

 continuous, with a slight emargination, the spines slender and pungent, the first 4 

 or 5 graduated, the rest subequal, 3.2 in head, lower than the soft rays which are 

 contained about 2.5 in head ; anal fin short, the second spine longest and strongest, 

 3 in head, the soft part high, the fifth or sixth ray longest, reaching almost to front of 

 anal, 2 in head; ventral with second ray produced, reaching vent; caudal truncate, 

 or with middle rays very slightly shorter, making the margin slightly concave. 



Color in life: Dorsal half of head and trunk and all of caudal peduncle scarlet, 

 ventral portion pale blue, almost white; a yellow longitudinal band, nearly as wide 

 as pupil, from preopercular margin straight across opercle and along body to lateral 

 line under last dorsal rays; 4 quadrate or oblong black blotchesjust under this band, 

 the first about under middle of spinous dorsal, second under last spines, third under 

 first rays, fourth under last rays; from each of the first three of these blotches a 

 square, well-defined yellow shade extends downward to belly or base of anal, a simi- 

 lar one from base of pectoral to ventral; 4 smaller black blotches at base of caudal, 

 two others, somewhat larger than the last, just in front of them on caudal peduncle ; 

 a row of 9 black, round dots on each side at base of dorsal fin, the first one smallest, 

 opposite membrane of first spine, the other 8 separated somewhat obscurely into 

 pairs, the first pair under middle spines, second under last spines, third under first 

 rays, fourth under last rays; 2 or 3 very small black dots on upper edge of caudal 

 peduncle; 2 or 3 more in front of dorsal on median line, each accompanied by a 

 similar one on either side; in some specimens a few scattering ones on top of head 

 behind eyes, sometimes regularly arranged; a few dark-brown spots behind eye; 

 various dark markings on side of head, without very definite pattern, but usually 

 2 oblique stripes on cheek, a heavy black blotch on interopercle and 2 on the ramus 

 of the mandible, which, with their fellows of the other side, make distinct cross- 

 bars on lower side of head usually extending across maxillary; chin and lower part 

 of opercle with dark spots; lateral line white, with a few broken spots, compara- 

 tively faint, just below it; iris red, with an inner ring of white surrounding the 

 pupil; spinous dorsal pale, the edge of the membrane black, this color bordered 

 below with faint yellow; soft dorsal pale, spotted throughout with light orange, with 

 a marginal band of the same, outside of which is a very narrow pale-blue edge; 

 ventral very pale-blue, the produced ray somewhat yellow ; anal pale-blue with some 

 light orange on last rays; pectoral and caudal uniform pale-reddish, unmarked. 



In spirits all the red and yellow markings disappear, the dark persists, and addi- 

 tional markings are brought out, as follows: Along the anterior and upper part of 

 trunk and crossing the lateral line are dark-brown vertical bars, difi'use and running 

 together, or separated and broken into round or quadrate blotches; in the middle 

 part of the course of the yellow longitudinal band appears a row of very small 

 black points; spots on soft dorsal dusky; dark mottlings on caudal; upper and 

 lower base of pectoral, and sometimes axil, dusky.
