AULOPUS. 
Formed by Cuvier, in Ms “ Regne Animal,” on a curious 
Mediterranean fish, which, on account of its adipose dorsal fin, 
had been placed with Salmo by Bloch and others. Its characters 
give it much affinity with fishes of the most remote families. Dr. 
Grunther has placed it with his Scopelidce. M. Valenciennes, 
Cuvier’s learned colloborateur, having received from Tenerifi’ 
the male and female of this sort, thought that they belonged 
to two ditferent species ; but since then, it has been ascertained 
that the first mentioned sex is always adorned, in this genus, 
with dorsal filaments, which do not exist in the female. In the 
last volume that has ever been published of his great work on 
fishes, the French author describes a second sort from Australia, 
but it had been previously published by Dr. Richardson.

This sort is so very scarce at Melbourne as not to have received 
any particular name. At Sydney, it appears to be much more 
common, and is known as Sergeant Raker.

Height of body five and two-third times in the total length ;
