Show 452 MR. J. Y. JOHNSON ON SOME N E W [June 3, interocular space, midway between the posterior nostril and the upper extremity of the gill-cleft; posterior nostril midway between the end of the snout and the eye. Five rows of teeth in the prse-maxillary, nearly all bicuspid, the outer row comprising about twenty teeth ; mandibular teeth scarcely larger than prsemaxillaries, bicuspid. Labial lobes large and covered with granular papillae; the cleft of the mouth measures three fifths the width of the buccal disk ; barbels measuring half the length of the head. Adipose fin quite indistinct. The origin of the first dorsal is nearly twice as far from the caudal as from the end of the snout; its first ray is scarcely prolonged, measuring a little less than the distance between the posterior nostril and the posterior extremity of the head. First pectoral ray little prolonged, a little shorter than the head, measuring about one third of the distance between its base and the anal, and not extending to the middle of the outer ventral ray. Ventral fins originating slightly in advance of the dorsal; the outer ray much thickened and a little prolonged, measuring half the distance between its base and the anal. Anal opening equally distant from the extremity of the ventrals and the origin of the anal. First anal ray two thirds the length of the ventral, halfway between the extremity of the ventral and the caudal. Caudal fin crescentically notched, with the outer rays a little produced and a little shorter than the head. Olive-brown above, closely spotted with darker. Total length 89 millim., without caudal 75 ; length of head 16; width of head 16 ; depth of body (above base of ventrals) 12. Specimens were obtained in the Andes of Ecuador (Milligalli) by Mr. Edward Whymper. 5. O n some n e w Species of Fishes from Madeira. By JAMES YATE JOHNSON, C.M.Z.S.
