Brown, paler below. Edges of scales narrowly darker. Fins all uniform brown- 
ish. Lower side of head and trunk with silvery reflections. One example, 295 mm. 
Cultriculus kneri (Kreyenberg and Pappenheim). 
Head 4; depth 4^ to 5; D. iii, 7, i; A. Ill, 11, i or 12, i; scales 47 in lateral 
line to caudal base and 2 more on latter ; 8 scales above lateral line, 2 below; 21 to 
23 predorsal scales; snout 3?- in head measured from upper jaw tip; eye 3* to 4; 
maxillary 3* to 3^ ; interorbital 3^ to 3^. 
Body elongately fusiform, compressed, lower profile little more convex than 
upper. Caudal peduncle compressed, least depth if to if its length or 2;' to 2f in 
total head length. 
Head width 2^ to 2+ in its length. vSnout conic, tip level with upper edge of eye ; 
length I to I in its width. Eye large, hind edge midway in total head length. 
Mouth large, lower jaw well protruded. Maxillary reaches opposite hind nostril, 
largely concealed by preorbital. Premaxillaries protractile. Jaw edges firmly cori- 
aceous. No.strils together, at last fourth in snout ; hind one slit, twice length of 
front one. Interorbital broadly convex. Broad preorbital f of eye ; first suborbital 
about half width of second which nearly covers cheek ; postorbital narrow, less in 
width than first suborbital. Opercle smooth. 
Gill-opening forward not quite oppo.site hind eye edges. Gill-rackers 4-I-15, 
lanceolate, about I of gill-filaments. Pseudobranchiae little less than gill-filaments. 
Pharyngeal teeth 2, 4, 4-5, 4, 2, hooked and some of larger with well-developed 
grinding-surfaces. 
Scales in even longitudinal rows; with 13 to 25 apical radiating striae; 
circuli fine. Breast convexly rounded ; belly from breast to vent with median 
keel over which scales do not pass. Lateral line complete, greatly deflected until 
just before ventral, then low along side of body and ascending midway along side of 
caudal peduncle ; tubes simple, each extending about half way over scale exposure. 
Dorsal origin midway between hind eye edge and caudal ba.se, slightly nearer 
eye in smaller example ; first branched ray i| to if in head. Anal begins entireh^ 
behind dorsal base ; first branched ray 2^ to 23 in head. Caudal deeply forked, 
pointed lobes about long as head. Pectoral reaches | to ventral, slightly longer 
than head. Ventral inserted well before dorsal or midway between snout tip and 
caudal base ; ^ to | to anal ; length i| to if in head. 
Back olivaceous-brown, sides and below silvery-white. Fins uniform brownish. 
Two examples, 122 to 153 mm. 
Culter hypselonotus Bleeker. 
Head 4:[ ; depth 4% ; D. II, 7 ; A. iir, 21, i ; scales 92 in lateral line to caudal 
base and 4 more on latter ; 20 scales above lateral line, 10 below ; 58 predorsal 
scales ; snout 35 in head measured from upper jaw tip ; eye 3f ; maxillar}^ 3 ; 
interorbital 5. 
Body elongate, strongly compressedj deepest at dorsal origin ; edges all rounded
