BIRDS OF LOWER CALIFORNIA. 241 



with a few low trees, cacti and bushes. Birds were fairly 

 numerous in these places, but on the side of La Giganta no 

 species worthy of note were found. 



The collections which I made in 1888 and 1889 on Santa 

 Margarita Island and Magdalena Island, and the peninsula 

 adjoining Magdalena Bay, indicate a marked lack of the 

 birds known as '" Cape species," which do not (with a few ex- 

 ceptions) extend northward abundantly for any great distance 

 on the western side of the peninsula. Whatever so-called 

 *'Cape species" were met with coastwise were found more 

 numerous in the interior and towards the Gulf coast, which 

 is much warmer, particularly in summer. 



In addition to the following standard works consulted in 

 the preparation of this catalogue, I have had considerable 

 assistance from the letters of Messrs. Belding and Anthony. 

 To Messrs. Ridgway and Belding I return my thanks for 

 their indispensable work of determining certain of the 

 species collected. Messrs. Anthony and Emerson have 

 kindly loaned me specimens for comparison.

 given, are intended to show the species they have met with 

 in certain localities, some new, others of corroborative in-
