upper jaw, fewer on sides; in lower jaw less numerous in front, a long 

 single row of somewhat stronger teeth on sides; eye not large; a small 

 nasal flap, and a 3- or 4-branched tentacle over eye and one at nape ; scales 

 rather large and regularly arranged; dorsal fin with a notch behind third 

 spine, and with one unbranched soft ray at its end, the membrane joined 

 to caudal; origin of anal under eleventh dorsal spine; lateral line as usual 

 in Auchenopterus. 



Color in spirits: Everywhere a nearly uniform faded pink, save breast 

 and lower side of head, which are paler ; a small, inconspicuous dark round 

 spot on dorsal fin, at twenty-third and twenty-fourth spines, a little 

 nearer base than margin, and made up of very small black punctnlations; 

 indications of a yellow tinge on front of dorsal and base of anal in life; 

 fins otherwise all pale. 



Puerto .Rico; known only from the type, a specimen 1.3 inches long, 

 obtained by the United States Fish Commission expedition to Puerto Rico 

 January 27, 1899. (rubescens. reddening.)

Head 3; depth 4.4; eye 5"; snout 4.2; maxillary 2.2; interorbital 6; scales 

 2-29-7; D. IV-XXIV, the longest spines 3 in head; A. II, 16, the longest 

 ray 2.25 in head; pectoral 1.3; A'entral 1.8; caudal 1.6. Body rather long 

 and slender, strongly compressed; head large, little compressed; snout 

 moderately sharp ; mouth large, maxillary reaching posterior border of eye, 

 the lips heavy, the jaws subequal or the lower very slightly projecting; 

 teeth conical and sharp, in more than one row in each jaw, most numerous 

 in front; a patch on vomer; a nasal filament, a 3- or 4-branched supraoc- 

 ular tentacle, and a 4-branched nuchal tentacle, the branches of the latter 

 each with a dark dot on their anterior surface. Dorsal originating over 

 edge of preopercle, of spines only, the second slightly longer than first; 

 second, third, and fourth graduated, the fourth comparatively short, thus 

 forming a notch partly separating the first 4 spines from rest of fin; 

 dorsal membrane joined low with caudal; anal free from caudal, about as 

 high as dorsal, its thirteenth and fourteenth rays longest; first anal spine 

 under tenth or eleventh dorsal spine ; caudal rounded, shorter than head, 

 of about 13 rays; pectoral large, reaching anal, of 12 rays; ventrals 

 moderate, of 2 rays, the spine not evident. Lateral line running high to 

 eleventh dorsal spine, here abruptly decurved two rows of scales, thence 

 median to base of caudal. 



Color in spirits: Body and head pale yellow; body with 4 heavy dark- 

 brown vertical bars, each about 4 rows of scales wide, extending on the 

 vertical fins; membrane of anterior dorsal spines, opercle, occipital, and 

 scapular region blotched with the same color; a dark bar backward and 

 downward from eye across cheek, rather more than one-half width of eye; 

 top of head between and behind eyes darkened; preorbital, maxillary, 

 'lips, and under part of head thickly punctulate with dark; dorsal and 

 anal barred with the extensions of the wide dark body bars, and with the
