VICTORIAN SPECIES OF THE GENUS GALAXIAS 
101 
ventrals. Ventrals originating at a point about equidistant between snout and 
base of caudal, extending half the distance from their base to origin of anal. 
Caudal emarginate, 7 6 in total length; its length equal to length of caudal 
peduncle which is twice as long as deep. 
Colour in spirit greenish-brown, with four prominent dark oval blotches 
on each side between base of pectoral and origin of dorsal. 
Described from a specimen (A.96, Nat. Mus. Victoria) measuring 84 mm. 
in total length, one of two examples from the Rubicon River, Victoria. 
Galaxias pusillus sp. nov. 
B.5or6; D.8 (7-8); A.IO (9-10); V.5; P.12 (10-12); C.13. 
Head 5 1, depth of body 7 5, in total length. Snout less than diameter of 
eye, 4 in head. Eye equal to interorbital width, 3 in head. Jaws equal or 
the lower slightly projecting, maxillary extending to vertical from anterior 
margin of eye. Gill- rakers long, slender, about 10 on lower part of anterior 
arch. Teeth in jaws subequal. 
Fig. 2. Galaxias pucillus sp. nov. 
Distance from origin of dorsal to base of caudal about 3 6 in total length. 
Origin of anal in advance of that of dorsal, posterior end of base of anal 
directly below that of dorsal. Pectoral extending slightly more than half 
the distance from its base to base of ventral. Ventrals originating at a point 
a little nearer the snout than base of caudal, extending one-third the distance 
from their base to origin of anal. Caudal rounded, its length equal to depth 
of body, 7 5 in total length. Caudal peduncle three times as long as deep. 
Colour in spirit pale yellowish with three longitudinal black lines on sides 
of body. 
Described from a specimen (A.97, Nat. Mus. Victoria) measuring 31 mm. 
in total length, one of a small series from Cardinia Creek, about 30 miles east 
of Melbourne, Victoria, obtained by Mr. A. Massola. Mr. Massola and 
other members of the Aquarium Society of Victoria have been successful in 
breeding these attractive little fishes in aquaria. 
In having 5-rayed ventrals, and the anal originating in front 
of the dorsal, this species agrees with Galaxias bullocki Regan 
from Chile and differs from all other species of the genus. On 
these characters Eigenmann (1924, p. 49) proposed Brachy- 
galaxias for G. bullocki, but a separate genus does not seem 
warranted.
