This species is very closely allied to G. cowzi, but is distinguished 
by the smaller eye, the somewhat shorter ventrals, less deep anal, 
and more slender caudal peduncle.

Depth of body about 6 in the length, length of head 52. Snout 
a little longer than eye, the diameter of which is 5 in the length 
of head, interorbital width 23. Lower jaw slightly projecting ; 
maxillary extending to below anterior 3 of eye. 8 gill-rakers on 
the lower part of the anterior arch. Dorsal III 8; distance from 
origin of dorsal to base of caudal 34 in the length of the fish. 
Anal III 9, commencing slightly in advance of the posterior end 
of the base of dorsal, when laid back not extending to the caudal. 
Pectoral extending 2 of the distance from its base to the base of 
ventral. Veutrals 7-rayed, originating at a point nearly equi- 
distant from tip of snout and base of caudal, extending 2 of the 
distance from their base to the origin of anal. Caudal emarginate. 
Caudal peduncle 13 as long as deep. Body with numerous irre- 
gular dark vertical stripes ; fins immaculate.

The typical example, from Cardinia Creek, measures 105 mm. in

11-13 (IV 7-9), commencing behind the middle of the dorsal, 
when laid back nearly reaching the procurrent caudal rays. 
Pectoral extending from + to a little more than 2 of the distance 
from its base to the base of ventral. Ventrals 7-rayed, originating 
at a point equidistant from eye and base of caudal or from middle 
or posterior part of pectoral and origin of anal, extending 2-3 of
