378 MR. C. TATE REGAN ON THE FISHES [Nov. 28, 
from Prof. W. B.* Spencer, agree very well with Johnston’s 
description of Galaxias atkinsonit from the River Pieman. They 
differ from the adult fish in the more slender body (depth 6-8 in 
the length, caudal peduncle 12-1? as long as deep), the smaller 
mouth with the jaws equal anteriorly, and the less distinct 
markings. 
17. GALAXIAS ROSTRATUS. 
Galaxias rostratus Klunz. Arch. f. Nat. 1872, p. 41. 
Depth of body 84 in the total length, length of head 52. 
Snout 14 as long as eye, the diameter of which is 44 in the length 
of head and 14 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 $ 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.

Lower jaw with the lateral teeth more or less distinctly enlarged 
and canmne-like. Depth of body 5-6 in the length, length of 
of head 42-42. Snout as long as or slightly longer than eye, the 
diameter of which is 4-42 in the length of head, interorbital 
width 24. Jaws equal anteriorly; maxillary extending to below 
anterior + or anterior 3 of eye. 7—9 branchiostegals. 8 or 9 gill- 
rakers on the lower part of the anterior arch. Dorsal 10-12 
(11I-IV 7-8); distance from origin of dorsal to base of caudal 
33-34 in the length of the fish. Anal 14-16 (IV-V 10-12), 
commencing below the anterior } of the dorsal, when laid back 
usually reaching the procurrent caudal rays. Pectoral extending 
3 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 # 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 ;
