specimen in the Paris Museum, which I considered to be the 

 type of Lesson's C. squamicolle, was really the Malaccan 

 species ; but a recent examination of this bird has proved to 

 me that it is no other than the Javan C. mentale. The 

 species being therefore without a title, I name it after Mr. A.

 ever feel grateful. 



The types are in my collection, the S being from Malacca,

XXII. — Notes on Mexican Birds.

 discuss so much the question of boundaries, which will be 

 fully gone into on another occasion, as to make known 

 various matters relating to many birds which have come 

 under our notice from the districts in question, with incidental 

 remarks upon the more general subject. 



In December of 1887 Godman arrived in Mexico by way 

 of New York and El Paso and the Mexican Central Railway, 

 and remained in the country till May of the following year : 

 during this time he travelled over a portion of Southern 

 Mexico and made a short trip in Yucatan. In all his excur- 

 sions he had collectors with him. Independent expeditions 

 were also organized to various points. Mr. W. B. Richardson, 

 of Boston, after collecting for a short time in the neigh-
