403 
Color in alcohol: Ground-color pale-brownish, a series of 9 quadrate dark blotches across back, 
separated by interspaces shorter than their own lengths, the first interspace just before front of first 
dorsal spine; apparently a yellow stripe from tip of snout through anterior nostril to middle of front of 
eye; a series of 13 black spots along the soft dorsal fin nearer the outer margin than base of the fin; 
other fins plain. 
Two specimens secured by Dr. Wood at Honolulu. Type No. 49701, U. S. N. M. The follow- 
ing are their comparative measurements and the numbers of tin rays and scales:

16. Brotula marginalia Jenkins, new species. Type. 
Family BHOTUXiIDlE. 
Brotula marginalis Jenkins, new species. Fig. 16. 
Body not much elongate, depth 5 in length. Head equal to depth. Caudal region rounded, not 
tapering to a point. Profile of head ascending in a straight line from tip of snout to front of dorsal. 
Greatest width of body near anterior end, about 1.5 in head; caudal region much compressed. 
Distance from tip of snout to anus 2.33 in length. Dorsal rays 96; fin beginning a little back of base of 
pectoral, of about uniform height throughout. Anal with 70 rays, beginning just back of anus, of same 
height as dorsal and continuous with it around caudal end of body. (In this example, which doubt- 
less is abnormal in this particular, the caudal part of the fin is conspicuously notched on axis of body.) 
Vertical height of dorsal and of anal a little less than eye, 4.75 in head. Snout from all aspects 
bluntly rounded, equal to horizontal diameter of eye. Eye on right side of specimen ovate, larger end 
posterior, longitudinal diameter 4 in head; eye on left side elongate ovate, constricted at middle. 
Maxillary reaching to below posterior margin of eye. Preorbital 2 in longitudinal diameter of eye. 
Mouth oblique. Teeth minute, villiform, in bands in each jaw and on palatines, in a V-shaped patch on 
vomer. Snout above with six tentacles, longest about equal to eye in length, two at lower end of each 
nasal bone, one on posterior rim of each anterior nostril. Lower jaw also with six tentacles, each longer 
than eye, three on each side, just back of symphysis. Anterior nostril with a very short tube, larger 
than the posterior, situated somewhat nearer eye than tip of snout. Posterior nostril almost sessile, 
having only very slightly raised rim. Movable spine on side of head arising from upper anterior angle 
of opercle. Gillrakers 3 on upper end of lower arm of arch. Branchiostegals 8. Pectoral rounded, 
longest rays 2 in head. Ventrals at symphysis of humeral arch, the two arising close together, each 
filamentous, 1.66 in head, bifid near middle, outer part the shorter, about half the length of inner 
from bifurcation. All parts of head and body scaled; scales elongate ovate, ctenoid, in 165 transverse 
series, 44 in transverse row at middle of body.
