NATURAL HISTORY OF VICTORIA. 



[Fishes. 



In old males Dr. Giinther observed that these caudal spines are 

 directed forwards, and I give woodcuts, of the natural size, to show 

 examples of both of these directions from specimens otherwise 



similar. The stripes vary considerably in 



different individuals. 



This beautiful species, with its con- 

 spicuous horse-shoe-shaped black mark on 

 the golden-yellow patch on each side, 

 seems to have suggested the fountain 

 'lTnroKpi'ivr), near Mount Helicon, sacred to the 

 Muses, produced by a stroke of Pegasus' 

 hoof, to Messrs. Quoy and Gaimard in 

 giving it the specific name. Like most 

 of the other Leather-jackets, it is greatly 

 infested with a large Isopodous crustacean, 

 which burrows in the hinder part of the 

 abdomen.

 specimen figured was got by blasting the 

 Lightning Rock there. It has not been
