PLATE XLIL 



a bird described among the ancients, which the moderns have not 

 hitherto determined, and which Cuvier assigns to this newly con- 

 structed genus, of which our Lanius Cayanus is the type. 



The present subject is to be considered, therefore, as the appro- 

 priate example of the generical distinction of the genus P^am, and it 

 is besides this, the type of another genus established lately among the 

 continental Naturalists, namely the Tityra of Vieillot, for the genus 

 Psaris, proposed by Cuvier, is not adopted. This last-mentioned 

 writer (Vieillot) assembled together, under the name of Becarde, 

 several species, of which the type, the Lanius Cayanus of Linnaeus, is 

 now before us. The generical distinction is the following : bill round 

 and glabrous at the base, robust, strait, rather depressed, convex 

 above and beneath ; upper mandible notched, and slightly incurvate 

 near the tip ; the lower one notched, turning up and acute at the 

 tip : nostrils oval, tongue large, short, lacerated at the end : mouth 

 ample and ciliated : first and second quill feathers longer : toes four^ 

 tM'ee being placed before and one behind.
