AULOPUS. 



Formed by Cuvier, in Lis "Kegne 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 Teneriff 

 the male and female of this sort, thought that they belonged 

 to two different 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 Baker.

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