spots, the upper row posteriorly becoming a dark edging to the fin. 

 Caudal dull red, edged with dusky. Anal very pale, edged with black- 

 ish. Pectorals light orange, usually with some small dark spots above. 

 Veutrals orauge, slightly darker anteriorly. 



Numerous series of i^ores on the body, those of the lateral Hue accom- 

 panied by shining golden bodies, as in other species of the genus. Ac- 

 cording to fishermen, these bodies are phosphorescent, shining at night ; 

 a statement which is probably true, although we have been unable to 

 verify it. Pores on sides of back not shining. jMost of the pores, as 

 in other species, accompanied by numerous small cirri or cilia. 



The arrangement of the lines of pores and shining bodies is not very 

 dift'erent from that found in P. margaritatus. It may be thus described 

 in detail. 



A series of pores beginning at tip of snout, extending down around 

 preorbital region, bounding the dark subocular blotch and joining almost 

 at a right angle with a series of pores which extends downward from 

 lower posterior corner of eye to angle of mouth. Another series diverges 

 from the first in front of eye, passing close below eye, then upward above 

 cheek, ending in a large pore behind preopercle. A curved series of pores 

 extending backward along opercle, and another parallel with it aloijg 

 subopercle. 



Two obscure series from front of eye along top of head, becoming 

 wide apart at the vertex, converging at the nape, then slightly diverg- 

 ing, converging in front of spinous dorsal, then again diverging to pass 

 around the fin, each at last becoming straight at front of soft dorsal, 

 extending close to its base to its last ray, there being about two pores 

 to each ray. Just below this series, at front of soft dorsal on each 

 side, begins a second series, with the pores wider apart and somewhat 

 irregular, ceasing near the middle of the soft dorsal fin. 



The lateral line proper next begins above upper posterior angle of 

 preopercle, whence a short branch passes directly upward. Opposite 

 front of soft dorsal, the lateral line is interrupted for a distance a little 

 more than diameter of eye. A short branch arises at this interruption 

 and passes upward and backward at an angle from the end of the 

 anterior part. Thence the lateral line passes straight to base of caudal. 



The next series arises just behind axil of pectoral, then curves 

 abruptly downward and backward, becoming straight opposite third ray 

 of anal, thence jn-oceeding to base of caudal, the pores small and close- 

 set, anteriorly bead-like and shining, becoming dull toward the tail. 

 ]!sext comes a double series on each side of base of anal, the two series 

 converging behind and finally coalescing. 



Another series begins at the middle of the base of the pectoral in front, 

 curves downward, around the base of the fin, and, proceeding directly 

 backward, ceases opposite vent. A series begins midway between gill 

 opening and ventral and, extending straight backward, ceases opposite 

 base of pectoral. Another begins, on each side, on lower side of head,
