Galaxias postvectis Clarke, t. c. p. 88, pl. v. 
Lower jaw with distinct lateral canines. Depth of body 
4-54 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 13-21. 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 34-42 in the length of the fish. Anal 1V—-V 
10-11, 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 3 to nearly } of the 
distance from its base to the base of ventral. Ventrals 7 if -rayed, 
originating at a point equidistant from snout or eye and base of 
caudal or from cumibemiloy part or middle of pectoral and origin of 
anal, extending 2—} 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.

A large female specimen, ready to spawn, measuring 265 mm. 
in total length, has not been included in the above diagnosis. 
The depth of the body is 2 of its length, the caudal peduncle is 2 
as long as deep, the maxillar y 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.
