ULTRAMARINE JAY. 



1 Garrulus ultramarinus, Bonap. 



PLATE CCXXXIL— Adult Male. 



Although the Ultramarine Jay has been described by Mr. Swainson, in 

 his Synopsis of the Birds of Mexico, under the name of Garrulus sordidus, 

 I retain the specific name "ultramarinus" previously given by the Prince 

 of Musignano. The only observations respecting its habits that I am aware 

 have been made, are the following, for which I am indebted to my friend 

 Thomas Nuttall.
