Psittacula, Briss. 



Pullaria, Linn. 



This bird has been placed in a different genus under the name of Agapornis, but does 

 not differ in its osteology from Psittacula passerina. Psittacula galgula and rubricollis 

 are also similar, except that the former has a very slight, but still a perfect furculum. 



Euphema, Wagl. 



Elegans, Gould. 

 Cranium broader in proportion to its length than in Trichoglossus, without a furculum ; 

 and in other respects similar to Trichoglossus versicolor, except in measurements. 

 Euphema chrysostoma is also similar.
