 and more slender caudal peduncle.

Depth of body about 6 in the length, length of head 54. Snout 

 a little longer than eye, the diameter of which is 5 in the length 

 of head, interorbital width 2|. Lower jaw slightly projecting ; 

 maxillary extending to below anterior ^ 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 3^ 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 |- of the distance from its base to the base of 

 ventral. Ventrals 7-rayed, originating at a point nearly equi- 

 distant from tip of snout and base of caudal, extending -| of the 

 distance from their base to the oi'igin of anal. Caudal emarginate.. 

 Caudal peduncle 1| as long as deep. Body with numerous irre- 

 gular dark vertical stripes ; fins immaculate.

The typical example, fi'om Cardinia Creek, measures 105 mm. in 

 total length ; I have been permitted to examine it by the courtesy 

 of Prof. L. VaiUant.
