[Vol. XLVIII 



Although most species of birds should have been nesting at this 

 season, March and April, veiy few nests were seen. 



Birds were collected chiefly by Messrs. H. E. Anthony and P. I. 

 Osburn, although many were obtained by Dr. Paul Bartsch and myself. 

 The naval officers attached to the ' Albatross' brought on board 

 numerous specimens of water birds. 



Lower California has not yet been fully explored ornithologically. 

 The following records, relating mostly to the distribution of the species 

 met with, include some localities not previously visited by ornithologists, 

 and are, with a few exceptions, restricted to localities visited by the 

 expedition. 



Fie;. 1. The 'Albatross' a1 San Josef Island, Gulf of California. 



The nomenclature is that of the A. O. U. list, with such additions as 

 have appeared in Ridgway's 'Birds of North and Middle America.' 



For information on the physiography of the localities here referred 

 to, reference may be made to part one of this series of reports, which 

 contains the narrative of the voyage with numerous illustrations. 



Colymbus nigricollis calif ornicus (Heermann) 



Eared Grebe 



The eared grebe was observed at several points in the Gulf, being 



quite common at San Josef Island, Agua Verde Bay, San Francisquito 



Bay, and Angel Guardia Island. Eight specimens, San Josef Island, 



March 30 and San Francisquito Bay, April 10.
