VICTORIAN SPECIES OF THE GENUS GALAXIAS 
99 
Ventrals 5-rayed. 
Origin of anal in advance of that of dorsal pusillus n.sp. 
Galaxias attenuatus (Jenyns). 
Mesites attenuatus Jenyns, Zool. Voy. Beagle, iii, 1842, p. 121, pi. 22, 
fig. 5. 
Austrocobitis attenuatus Ogilby, Proc. Linn. Soc. Nevv^ South Wales, 
xxiv, 1899, p. 158. 
Galaxias attenuatus Regan, Proc. Zool. Soc., 1905, ii (1906), p. 368, 
pi. 12, fig. 1, and pi. 13, fig. 2. 
Galaxias versicolor Castelnau, Proc. Zool. Acclini. Soc. Viet., i, 1872, 
p. 176. 
Galaxias amaenus Castelnau, ibid, p. 178. 
This is the common and most widely distributed species of 
the Galaxiidae. It occurs iu the extreme south of South 
America, the Falkland Islands, New Zealand, southern Aus- 
tralia, and Tasmania. It is the only form in Australia that is 
known to enter the sea. The life-history of attenuatus has 
received considerable attention in New Zealand, where it 
forms the bulk of the commercially valuable whitebait. 
It is evident from the original descriptions of G. aynaenus 
and G. versicolor that both were described from small speci- 
mens of attenuatus. 
Galaxias coxii Macleay. 
Galaxias coxii Macleay, Proc. Linn. Soc. New South Wales, v, 1880, 
p. 45; Regan, Proc. Zool. Soc., 1905, ii (1906), p. 380, pi. 12, fig. 2. 
Galaxias nigothoruk Lucas, Proc. Roy. Soc. Viet. (2), iv, 1892, p. 28. 
In Victoria this species appears to be confined to the moun- 
tainous country east of Port Phillip Bay. Some of the largest 
specimens in the collections of the National Museum, measur- 
ing up to 190 mm. in total length, were obtained in Lake Tali- 
Karng, near the top of Mount Wellington (5,363 ft.). This 
lake or tarn has been formed by a landslip and has no visible 
outlet. 
A feature of the colouration of this species is a large dark 
blotch immediately above the base of each pectoral fin. 
G. ajfinis Regan from Tasmania is very doubtfully distinct 
from G. coxii. 
Galaxias truttaceus (Cuvier). 
Esox truttaceus Cuvier, Regn. Anim., ed. 1, ii, 1817, p. 184. 
Galaxias ocellatus McCoy, Intercol. Exhib. Ess. No. 7, 1866, p. 14. 
Next to G. attenuatus this is the most common species of 
the genus in Victoria. It is readily recognized by the trout- 
like black spots on the sides of the body.
