races on the margins of their habitats. Bj J. Grinnell & H. S. Swarth. 

 University of California Publ. Zool. vol. 10, 1913, pp. 197-406, pis. 6-10.] 



The San Jacinto Mountains are the southernmost part of 

 the coast-range of Ca]ifornia_, and are cut off on the north by 

 the San Gregorio Pass^ through which runs the Southern 

 Pacific Railway to Los Angeles, They rise to a height of 

 10,800 feet and thus include a considerable area of what is 

 termed by Merriam, the Boreal zone, as is illustrated in the 

 map accompanying this paper. 



Messrs. Grinnell and Swarth spent the great part of the 

 summer of 1908 in exploring this region, which was previously 

 comparatively little known, and they give in this memoir a 

 complete account of the Mammal and Bird fauna, as well as 

 a number of interesting general observations and deductions. 



Out of 169 species of birds met with they found 22 

 belonging to the boreal fauna ; and, on comparing this with 

 the numbers of species found in other isolated boreal areas in 

 southern California, they come to the conclusion that "the 

 smaller the disconnected area of a given zone the fewer 

 the types which are persistent therein," so that some of 

 the boreal areas further north have a much more restricted 

 boreal fauna owing to their smaller size. 



Another matter discussed is the contrast of the fauna to 

 the west and east of the San Jacinto range : on the west 

 side the climate is comparatively moist and the slopes are 

 gradual, while on the east the slopes are so steep that the 

 range of life-zones from the Lower Sonoras through the 

 Transition to the Boreal is all crowded into about three 

 miles, while the country at the base of the mountains is one 

 of the driest and most arid in the world. 



Gurney's Norfolk Bird- diary. 



[Ornithological Report for Norfolk (1912). By J. H. Gurney, F.Z.S. 

 Zoologist, 1913, pp. 161-181.] 



Mr. Gurney^s annual report always contains some matters 

 of interest. This year a wonderful migration-rush waa 

 witnessed by Messrs. Rivere and Long on the north coast of 

 Norfolk, near Hunstanton. It seems to have begun on the 

 evening of Nov. 6, when the wind was light from the south.
