NANNOCHARAX SEYBOLDI, new species 
PLATE 35, FIGURE 1 
Holotype.-—U.S.N.M. No. 118757, 32.9 mm. in standard length 
(tip of snout to base of caudal fin rays), collected by Dr. Wm. M. 
Mann at Bellyella. 
Paratypes—1 specimen, U.S.N.M. No. 118759, collected by Dr. 
Mann at Bellyella; 3 paratypes, U.S.N.M. No. 118758, collected by 
Dr. Mann at Bromley. 
Description.—Based on the holotype and 4 paratypes. Detailed 
measurements of 4 specimens are expressed in hundredths of the 
standard length, in table 2, for convenience in comparing these pro- 
portions with those for other species. 
The long, slender teeth with bifid tips are set close together, num- 
bering about 8 in the upper jaw and 10 in the lower. There are no 
teeth on the maxillary; the mouth is small and movable; the snout is 
somewhat pointed; interorbital space flat; eye large, about equal to 
length of snout; gill rakers short about 3+6; gill membranes attached 
to the isthmus a short distance forward; origin of dorsal a little 
behind pelvic insertion and a little closer to origin of adipose fin 
than to tip of snout; lateral line complete, extending along middle 
of side; pectoral fins long, and extending past pelvic insertion; pelvic 
fins reaching about halfway between anus and anal origin; caudal fin 
deeply forked; first branched ray of dorsal and anal fins longest; 
third ray of pelvic fin longest, the first two rays simple, and the next 
7 branched, totaling 9 in that fin; the second pectoral ray longest, 
the first two rays of this fin simple. 
There are 11 pale brown saddles on the back, 3 in front of dorsal 
fine, 2 under base of that fin, 4 between the dorsal and adipose fins, 
one under adipose and the last on caudal peduncle; the brownish sad- 
dles do not quite connect with 11 or 12 irregular brownish blotches 
along midsides that appear to be on the scales; under the scales and 
more deeply beneath the skin are 5 brown blotches along the midsides; 
pigment area at base of first few anal rays; paired fins pale; a brownish 
opercular spot; sides of snout with brown band and dorsal surface 
of snout brown; midbase of caudal fin brownish, and two other 
smaller pigment areas in each lobe of the caudal fin; two more or less 
distinct brownish bars across dorsal fin; ventrally the color is ab- 
ruptly paler below the blotches along the sides. 
Remarks.—This new species is closest to NV. intermedius and may 
prove to be a subspecies of it when extensive collections have been 
made along the west coast of Africa. It differs from intermedius in
