Mr. J. Dwight has recently written an important essay on the 

 ' Horned Larks of North America ' in the ' Auk ' for April, 1890. 

 He traverses the conclusions of Mr. Henshaw and divides the 

 American forms into some additional races, which, more Americano,

Subsp. 1^. Otocorys adusta. 



Otocoris alpestris adusta, Divight, t. c. p. 148. 



Ilab. Southern Arizona and New Mexico, Western Texas, and 

 southward into Mexico. 



Subsp. »;. otocorys merrilli. 



Otocoris alpestris merrilli, Bicight, t. c. p. 153. 



Hab. Eastern Oregon, "Washington, and British Columbia, between 

 the Cascade and Rocky Mountains ; southward in winter into 

 Nevada and California (J. DwigJit). 



Subsp. B. Otocorys pallida. 



Otocoris alpestris pallida, Dici(/ht,t. c. p. 154 (e.i- Tomisend, MSS.). 



Hab. Lower California and Sonera (/. Divight).

 had proposed for the Central-Asian race of Otocorys penicillaia, 

 obliges me to change the name for the latter bird, and I therefore 

 alter it as follows : —
