Mr. Bangs recognizes three, instead of two^ races of the 

 Scaled Partridge or Quail. These are Callipepla squamata 

 pallida Brewster, from Arizona and New Mexico, and C. s. 

 castanogastris Brewster, from the lower part of the valley 

 of the E/io Grande in Texas and the neighbouring parts of 

 Mexico, while the type-form C. s. squamata (Vig.) is 

 restricted to the Valley of Mexico. 



In the second note, Mr. Bangs separates the Magpie- Jay 

 of Costa E-ica from that of southern Mexico and Guate- 

 mala under the new subspecific title of Calocitta formosa 

 pompata.

As is well known to most of our readers, Mr. Beebe, who 

 is the Curator of Birds at the Zoological Park in New York, 

 is engaged in the preparation of comprehensive work on. the 

 Pheasant family, and now, under the last of the titles in the 

 list given above, he presents to us some of his preliminary 

 studies. It has always been a difficult matter to draw up a 

 satisfactory classification of the Pheasant family, but 

 Mr. Beebe has discovered a character which he believes to 

 be a fundamental one and by which he is confident he can 

 divide this large family into four groups. This character is 

 the method of the moult of the tail.
