[All the specimens obtained, with the exception of the last, were immature and 

 in moltingr condition; thus the measurements given are of little importance. In all, 

 the bill and bare orbital region is [jure unshaded yellow, varying little, if any, with 

 the s[)ecimen, being of a deep lemon-, or nearly chrome-yellow, the face more 

 citreous. The skin over the whole body also, as well as the underside of the claws 

 (possibly oidy in young birds), is yellow. We did not notice, in examining this species, 

 the leaden-blue outer ring to the iris, afterward found to be a constant feature in 

 P. hitdsonica.]

The Black-billed Magpie is one of the most characteristic birds of the 

 Interior, but its abundance varies greatly, in fact, almost unaccountably; 

 with the locality ; it is also one of the most conspicuous birds of that region.
