268. Auchenopterus cingulatus Evermann & Marsh. 
Head 3; depth 4.4; eye 5; snout 4.2; maxillary 2.2; interorbital 6; scales 2-30-3, 7 in transverse 
series. T>. xxvin, the longest spines 2.75 in head; A. ii, 16, the longest ray 2.75 in head; pectoral 1.3; 
ventral 1.8; caudal 1.6. Body rather long and slender, strongly compressed; head large, little com- 
pressed; snout moderately sharp; mouth large, maxillary reaching posterior border of eye, lips heavy, 
jaws subequal or 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 supraocular 
filament, and a 4-branched nuchal filament, branches of latter each with a dark dot on its anterior 
surface; dorsal originating over edge of preopercle, of spines only, second slightly longer than first; 
second, third, and fourth graduated, fourth comparatively short, thus forming a notch partly separating 
first 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, 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 5 heavy dark-brown vertical bars, each 
about 4 rows of scales wide, extending on vertical fins; membrane of anterior dorsal spines, opercle, 
occipital, and scapular region blotched with 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 extensions of the wide, dark body-bars, and with alternating narrower pale interspaces; 
caudal mottled or irregularly barred with grayish, its base with the plain pale-yellow ground-color, 
which is sharply separated from rest of tin by a curved dark line; posterior half of pectoral with dark 
bars formed of dots on rays, first bar plainest; basal half of pectoral pale; ventral with basal portion 
dark, rest barred like pectoral. 
A pretty and strongly marked blenny, known only from Porto Rico; four specimens obtained 
from the coral reefs at Ponce, and one at Puerto Real. The type, No. 49375, U. S. N. M., from Ponce, 
is 0.8 inch long, and none of the cotypes exceeds 1 inch.

269. Auchenopterus fasciatus (Steindachner), 
Head 3.5; depth 4.6; eye 4.5; snout 4.2; maxillary 2.3; mandible 2; interorbital 5.4; scale 2-31-3, 
7 m transverse series; D. xxx, 1; A. ii, 17; P. 1.3 in head; V. 1.4; C. 1.4. Body slender, compressed, 
head narrow, snout pointed; mouth rather large, lower jaw slightly projecting, maxillary reaching 
posterior edge of pupil; gill-membranes broadly united across isthmus; eye small, above axis of body; 
profile rising gently and regularly from tip of snout to origin of dorsal fin, from which it continues in a 
nearly straight line to caudal peduncle; a small ocular cirrus and a small one on side of nape; fourth 
and fifth dorsal spines shorter than those before or after, others of approximately equal length; anal 
rays about as long as dorsal spines, the tips projecting beyond membrane; scales large, cycloid; belly,
