length 2 in head. Teeth rather small, the outer and posterior a little 

 enlarged; lower jaw slightly included. Preorbital narrow, its least 

 breadth 9 in head ; interorbital space broad, convex, its width 2f in head ; 

 preopercle moderately serrate. Gill -rakers much longer and more numer- 

 ous than in B. aurolineatum and other species, about 18 on lower part of 

 anterior arch, the longest least depth of preorbital. Scales notably 

 smaller than in any other species of the geuus, those above lateral line in 

 very oblique series, those below more nearly horizontal, and none of 

 them specially enlarged; soft fins scaly, as usual. Dorsal spines slen- 

 der, rather low, the fourth or longest 2-^ in head; soft dorsal long and 

 low, the longest ray 3| in head ; caudal deeply forked, the upper lobe l-^ in 

 head; anal rather low and small, its longest rays 3^ in head, not reaching, 

 when depressed, to the tip of the last rays; second anal spine notably 

 longer and stronger than third, 2? in head, reaching, when depressed, a 

 little past base of last ray; veutrals 1 in head; pectorals If. Color in 

 spirits pearly gray, with continuous brown streaks (golden in life), 1 on 

 the median line above from tip of snout to dorsal, 4 on each side of top 

 of head above eye, 3 of these extending 011 the body, but only the second 

 continuous, this very distinct and reaching last ray of dorsal; below 

 these, 2 extending backward from eye, the uppermost distinct anteriorly, 

 fading behind, the lowest fading anteriorly; below this traces of another 

 dusky stripe ; there are thus 3 or 4 distinct longitudinal streaks on body, 

 with 2 or 3 fainter ones; fins pale, probably yellowish in life. This is 

 one of the smaller species, probably never exceeding a foot in length. It 

 is allied to B. aurolineatum and B. rimator, but deviates from the ordinary 

 Jiathystoma type more than either of these. Here described from No. 9839, 

 U. S. N. M., sent by Poey from Cuba. West Indies; Bermudas to Brazil;

This genus is closely allied to Hwmulon, differing in the short snout, 

 high supraoccipital crest, oblique mouth, and increased number of gill 

 rakers. The form of the body is peculiar, the dorsal and anal long and
