240 PSIl'TACID.E. 



Some specimens have less black on the wing-coverts and a 

 bluish tinge on the head ; apparently they are young or immature 

 birds. 



It has been said that this bird occurs in the island of Cozumel, 

 on the authority of Dr. Cabot, but more recent collectors have not 

 found it there. Also the locality Venezuela, mentioned by De 

 Souance, requires confirmation.
