Show 378 MR. C. TATE REGAN ON THE FISHES [Nov. 28, from Prof. W. B. Spencer, agree very well with Johnston's description of Galaxias atkinsonii from the River Pieman. They differ from the adult fish in the more slender body (depth 6-8 in the length, caudal peduncle 1-f-l-f as long as deep), the smaller mouth with the jaws equal anteriorly, and the less distinct markings. 17. G a la x i a s r o s t r a tu s . Galaxias rostratus Klunz. Arch. f. Nat. 1872, p. 41. Depth of body 81 in the total length, length of head 5|. Snout 11 as long as eye, the diameter of which is 4y in the length of head and 11 in the interorbital width. Jaws equal anteriorly; maxillary extending to below middle of eye. 6 branchiostegals. Dorsal 11. Anal 14, commencing a little behind the origin of the dorsal. Pectoral extending much less than 1 of the distance from its base to the base of ventral. Ventrals 7-rayed, originating at a point equidistant from anterior margin of eye and base of caudal. A dark spot on the base of the caudal fin. Mersey River. Total length 130 mm. Evidently allied to G. occidentalis and G. waitii 18. G a la x i a s t r u t t a c e u s . (Plate XIII. fig. 4.) Galaxias truttaceus Cuv. Regne Anim. ii. p. 283 (1817); Cuv. & Val. Hist. Nat.

Jaws equal anteriorly; maxillary extending to below anterior 1 or anterior 1 of eye. 7-9 branchiostegals. 8 or 9 gill-rakers on the lower part of the anterior arch. Dorsal 10-12 (III-IV 7-8); distance from origin of dorsal to base of caudal 3f- 3-f in the length of the fish. Anal 14-16 (IV -V 10-12), commencing below the anterior J- of the dorsal, when laid back usually reaching the procurrent caudal rays. Pectoral extending \ the distance from its base to the base of ventral. Ventrals 7-rayed, originating at a point equidistant from eye and base of caudal, extending f of the distance from their base to the origin of anal. Caudal emarginate. Caudal peduncle a litttle longer than deep. Olivaceous, with purplish ocellated spots; upper lip dark ; an oblique dark stripe running back from below the eye |
