This bird, if distinct, is the South-western representative of the common P. Perspicillata, having been procured in this form on' the 
shores of California. The size of the two birds is about equal, and the only difference observable between them is, that the one now 
under consideration has a rather longer, narrower, and less swollen bill ; with the white patch on the head smaller and anterior to the 
eye. The accompanying engraving exhibits these peculiarities.
