(Plate XIII. fig. 1 .) Galaxias auratus Johnston, Proc. Roy. Soc. Tasmania, 1881, p. 131 (1882). Lower jaw with the lateral teeth somewhat enlarged. Depth of body about 5 in the length, length of head about 4. Snout scarcely longer than eye, the diameter of which is 41 in the length of head, interorbital width 2J-. Jaws equal anteriorly; maxillary extending to below anterior | of eye. 7-9 branchio-stegals. 10 gill-rakers on the lower part of the anterior arch. Dorsal IV 8 ; distance from origin of dorsal to base of caudal 3| in the length of the fish. Anal IV 10, commencing below the middle of the dorsal, when laid back extending to the procurrent caudal rays. Pectoral extending i the distance from its base to the base of ventral. Ventrals 7-rayed, originating at a point equidistant from posterior margin of prfeoperculum and base of caudal, extending nearly to the vent. Caudal emarginate. Caudal peduncle as long as deep. Reddish above, golden on the sides and beneath ; upper part of head and body with numerous rather large purplish spots ; fins pale, the dorsal, anal, and ventrals with the free edge blackish. Neighbourhood of the Great Lake, Tasmania. The description above is based on a single specimen measuring 125 mm. in total length, received from Mr. R. W. Johnston in 1880. The species is said by him to be confined to the neighbourhood of the Great Lake, at an altitude of about 4000 feet, and to attain a larger size than any other member of the genus. He gives the following measurements of a large specimen :-Total length 9| inches; length, without caudal, 8,) inches ; length of head \i. e. including opercular flap] 2| inches; depth of body nearly 2 inches; length of snout | inch; interorbital width 1 inch. The species is especially distinguished from the allied G. trut-taceus by the larger head and the more posterior position of the ventrals. |
