Show ~"° MR. G. A. BOULENGER ON THE [Apr. 15,. on each side below the dorsal fin ; belly white; dorsal and caudal fins with round black spots. Total length 100 millim. Several specimens. Distinguished from the preceding species and from A. uban-gensis by the smaller eye ; from the former by the shorter, from the latter by the longer maxillary barbel. 31. AMPHILIUS1 BREVIS, sp. n. (Plate XXIX. fig. 3.) Depth of body 6 to 6| times in total length, length of head 3| to 3| times. Head much depressed, a little longer than broad ; snout broadly rounded, ^ the length of the head ; eye very small, 9 or 10 times in length of head, 2| or 3 times in interocular width; maxillary barbel § or f length of head, scarcely longer than the outer mandibular, inner mandibular about $ length of head. Dorsal I 6, equally distant from the end of the snout and the root of the caudal; adipose fin once and a half to twice as long as the rayed dorsal, 1^ to 1^ as long as its distance from the latter. Pectoral longer than the ventral, § the length of the head. Anal II 6. Caudal feebly emarginate. Caudal peduncle as long as deep. Brown above, clotted with black; belly white ; caudal peduncle blackish towards the base of the caudal; fins white, caudal with a large rhomboidal or cruciform black marking. Total length 48 millim. Two specimens. This species is most nearly related to A. platychir Gthr., which differs, among other points, in having the dorsal fin nearer the end of the snout than the caudal, and the caudal peduncle longer than deep. 32.

Depth of body 7\ to 8 times in total length, length of head 5 to 5| times. Head 1\ to If as long as broad, nearly smooth above, covered with papillose skin ; snout half length of head, obtusely pointed, projecting but slightly beyond the mouth ; space between the two nostrils at equal distance from the end of the snout and from the eye, or a little nearer the latter; eye superolateral, its diameter 6 to 7 times in length of head, twice in interocular width; barbels thick and papillose, annulate, maxillary ^ length of head, outer mandibular \, inner mandibular \ ; occipital process narrow, 4 times as long as broad, narrowly separated 1 Amphilius Gthr. 1864, =•= Anoplopterus Pfeff. |
