Galaxias postvectis Clarke, t. c. p. 88, pi. v. Lower jaw with distinct lateral canines. Depth of body 4-51 in the length, length of head 4-5. Snout as long as or a little longer than eye, the diameter of which is 4-5 in the length of head, interorbital width I f -2i. Jaws equal anteriorly; maxillary extending to below posterior part of eye. 8 or 9 branchiostegals. 10 or 11 gill-rakers on the lower part of the anterior arch. Dorsal IV 7-9 ; distance from origin of dorsal to base of caudal 34-4-| in the length of the fish. Anal IV -V 10- 1 1 , commencing below or a little behind the origin of dorsal, when laid back extending to or a little beyond the base of the caudal. Pectoral extending from more than J, to nearly J- of the distance from its base to the base of ventral. Ventrals 7-rayed, originating at a point equidistant from snout or eye and base of caudal or from anterior part or middle of pectoral and origin of anal, extending | of the distance from their base to the origin of anal. Caudal truncate. Caudal peduncle from to as long as deep. Brownish, with narrow light vertical stripes, which may be undulating or irregular or may form reticulations; often a light vertical bar above the base of pectoral, succeeded by a dark purplish blotch.

The depth of the body is -f- of its length, the caudal peduncle is as long as deep, the maxillary does not extend beyond the middle of the eye, the origin of the anal fin is only a little in advance of the middle of the dorsal. These peculiarities appear due partly to the condition of the fish, partly to individual variation. 13. G a la x ia s a le p id o tu s . Esox alepidotus Forster, Descript.
