papillae. Small barbel near end of maxillary largely concealed. 

 Each jaw edge as firm, entire homy sheath. Nostrils together, 

 separated by short skinny flap, at last fourth in snout. Interorbital 

 broad, slightly convex. 



Gill-opening forward nearly to hmd eye edge. Rakers, about 

 16 + 65, weak, flexible, o in filaments and latter about equal eye. 

 Pharyngeal teeth, 2, 4, 5 — 5, 4, 2, each with broad grinding surfaces 

 and no terminal hook. Each pharyngeal arch with an outer row of 

 four extra deciduous teeth; these more obtuse and without grinding 

 surfaces. 



Scales large, rather narrowly uniform in exposure; scarcely smaller 

 on caudal base, though much more so on breast, so about 18 trans- 

 versely across between pectoral origins. Free pointed scaly ventral 

 flap about two-fifths of fin. Scales finely striate, about 24 to 28 

 basal and 60 to 70 apical, circuli all very fine but not complete 

 apically. Lateral line midway along side, complete, inconspicuous, 

 nearly straight, and with small simple tubes. 



Dorsal origin about midway between snout tii> and caudal base, 

 upper edge concave, first branched ray longest and extends far back 

 as tip of last or 1| to caudal base. Anal inserted about opposite 

 tip of depressed dorsal, fin falcate, with first branched ray longest 

 and reaching slightly beyond caudal base, though not quite to hind 

 limit of caudal squamation. Caudal deeply forked, lobes pomted 

 and upper little longer; fin large. Pectoral moderate, extends 

 three-fourths to ventral. Latter inserted about opposite third 

 branched dorsal ray base, and fin three-fourths to anal, though not 

 quite to vent. 



Color in alcohol deep dusky -bro\m, paler or more broA\aiish below, 

 on belly, and under surface of head. On sides and back edges of 

 each scale slightly darker than general color. Lips pale. Fins all 

 dusk}', and on lower fins more or less dusky blackish on outer 

 portions with narrowed paler edges. Iris dull slaty. 



Length, 210 mm.

Also No. 48513, same data, in all three paratypes. These show: 

 head, 3^ to 3i, depth, 3^ to 3§; D. in, 10 or iii, 11; A. ii, 5 or 6; 

 scales, 30 to 32 in lateral line to caudal base and 3 or 4 more on latter; 

 5 scales above lateral line and 5 below; 10 or 11 predorsal scales; 

 snout. If to 2 in head; eye, of to 7; maxillary, 2 to 2J; interorbital, 

 2^ to 22; length, 154 to 180 mm. 



This species falls with Labeo nasus Boulenger and Labeo greenii 

 Boulenger, both from the Kongo, according to Boulenger's key, as it 

 has 16 or 17 scales around the caudal peduncle. It differs from 

 either, however, in the more obtuse snout, which, though finely
