Zoology.-] NATURAL HISTORY OF VICTORIA. [Fw/ifs. 



Dr. Glinther in establishing the genus Trachinops for the 

 Sydney T. tccniatus gives " scales cycloid " as one of the generic 

 characters ; but Prof Kner describing the same species (Reise 

 der Novara ZooL, Theil, Fische, p. 216) says, "Die Schuppen 

 sind von miissiger Grosse, weich, und am ganzen Vorderrumpfe 

 glattrandig, gegen den Schwanz aber zeigen sie den Bau ctenoider 

 Schuppen, am festsitzenden Eude eiuen Fiicher von 10-12 RacUen 

 und gegen das freie Ende coucentrische Furchen und ein feiues 

 Netz mit sich bildeuden Kurtzen Spitzen in mehreren Reihen, die 

 am freien Rande zu langern wimpern-ahnlich Zahnchen werden," 

 and these remarks apply so well, as far as the hinder portion of 

 the body goes, that I have altered the generic character for both 

 species to "scales ctenoid." In the present species, I think all 

 the large scales are ctenoid. 



Found occasionally in abundance about the piers in Hobson's 

 Bay. Not figm-ed before.
