Show 1903.] FISHES FROM SOUTHERN CAMEROON. 23 jaw, 8 in the outer row of the lower jaw; length of lower border of second suborbital equal to diameter of eye. Gill-rakers moderately elongate, closely set, 20 to 23 on lower part of anterior arch. Dorsal II 8, entirely behind base of ventrals, originating a little nearer caudal than end of snout, twice as deep as long. Adipose fin small, 2| or 2§ times as distant from the rayed dorsal as from the caudal. Anal III 13-15. Pectoral as long as head, reaching ventral or nearly so far. Caudal forked. Caudal peduncle as long as deep. Scales 25 , 2 between lateral line and ventral. Silvery, brownish on the back; a black humeral spot and a black lateral band, commencing under the dorsal and extending on the median rays of the caudal; dorsal, caudal, and ventral fins lemon-yellow. Total length 130 millim. Four specimens; Kribi River and Mvile River. Very closely allied to A.fuchsii Blgr. and A. kingsleyce Gthr. Distinguished from the former by the less massive form and the longer pectoral fin ; from the latter by the more posterior position of the dorsal fin and the larger eye; from both by the more numerous gill-rakers. 9. A lestes macrolepidotus Cuv. 10. D istichodus notospilus Gthr. 11. X enocharax spilurus Gthr. Cyprinlele. 12. L abeo annectens, sp. n. (Plate II. fig. 1.) Body compressed, its depth nearly equal to length of head, 4 J to 5 times in total length. Head 1J- as long as broad ; snout rounded, strongly projecting beyond the mouth, with numerous nuptial tubercles; eye supero-lateral, in the second half of the head, its diameter 5 to 7 times in length of head, 2.| to 3| times in interocular width ; width of mouth, with folded lips, \ to length of head ; rostral flap and posterior border of lip feebly denticulated; inner surface of lip with numerous feeble, transverse plicae; a small barbel hidden in the folds at the sides of the mouth. Dorsal III 9-10, with strongly notched border; the longest ray equals the length of the head and twice that of the last; the fin equally distant from end of snout and from root of caudal. Anal II 5 ; longest ray § length of head. Pectoral rounded, a little shorter than head, not reaching ventral; latter reaching or nearly reaching vent, its first ray falling under the ninth (sixth branched) ray of the dorsal. Caudal deeply forked, with pointed lobes. Caudal peduncle 1| as long as deep. Scales 36-39^-, 3 between lateral line and ventral, 12 round caudal peduncle. Olive above, whitish beneath, with a rather indistinct darker lateral band ; fins greyish. Total length 210 millim. |
