Freshwater Fishes from Southern Cameroon. 441 
with 11 or 12, the latter with 12 or 13 rays; dorsal origi- 
nating a little nearer head than root of caudal, its first ray 
corresponding to the tenth scale of the lateral Hne ; some of 
the posterior dorsal rays produced into long filaments. Pec- 
toral about 2 length of head. Caudal acuminate, median 
rays produced into filaments. Caudal peduncle nearly twice 
as long as deep. 27 scales in a longitudinal series, 10 in a 
transverse series. Yellowish olive, most of the scales with 
a crimson spot or vertical bar; head with crimson wavy lines; 
fins dark, all except the pectorals with small crimson spots. 
Total length 50 millim. 
‘T'wo specimens from the Kribi River. 
This species is named in honour of Dr. E. Lénnberg, of 
Upsala, the author of several contributions to the fish-fauna 
of Cameroon. 
Pelmatochromis longirostris. 
Teeth in 3 series in each jaw, outer largest. Depth of 
body equal to length of head, 3 times in total length. Snout 
narrow, obtusely pointed, with slightly convex upper profile, 
more than one third length of head; diameter of eye 34 to 
4 times in length of head and equal to or a little greater 
than interorbital width; maxillary not reaching to below 
anterior border of eye; 2 or 3 series of scales on the cheek ; 
large scales on the opercle. Gill-rakers short, tubercular, 
notched, 9 or 10 on lower part of anterior arch. Dorsal 
XIV-XVI 8-9; spines increasing in length to the last, 
which measures # to $ the length of the head; middle soft 
rays produced, a little shorter than the head. Pectoral 2 to 2 
length of head. Ventral produced into a filament, reaching 
origin of anal or beyond. Anal III 6-7, third spine nearly 
as long as last dorsal. Caudal rounded-subacuminate. 
Caudal peduncle as long as deep. Scales smooth, with fine 
concentric striation, 28-30 = ; lat. 1. 2. Yellowish or 
pale brown, the scales edged with darker, or with rather ill- 
defined dark longitudinal streaks; a more or less distinct 
dark horizontal streak behind the eye; vertical fins with 
dark spots forming more or less regular bars; these numerous 
and usually very regular on the caudal fin; outer rays of 
ventrals white. 
Total length 115 millim. 
Seven specimens from the Kribi River. 
Most nearly related to P. Batesiz, Blgr., which has a 
shorter and broader snout, 4 series of scales on the check, a 
deeper body, more dorsal (10-11) and anal (8) soft rays, and 
a different coloration.
