style. The other genera treated in the present number are 
Pagodroma, Bulweria , Macronectes , Fulmarus, D option, 
Halobcena, and Prion. Macronectes, we may remark, is a 
new name for Ossifraga, it having been discovered that the 
latter term has been previously used in Zoology in 1885. 
The next number, we believe, will be mainly devoted to the 
Albatrosses, and Part VI. will conclude the work. 
62. Grinned on the Birds of the San Bernardino Mountains . 
[The Biota of the San Bernardino Mountains. By Joseph Grinnell. 
University of California Publications in Zoology, vol. v. No. l,pp. 1-170. 
Berkeley, Cab, 1908.] 
This memoir contains the results of explorations of the 
San Bernardino Mountains in 1905, 1906, and 1907. But 
some of our readers may ask, where are these mountains ? 
To this we answer, in the words of the author, “ The San 
Bernardino Mountains constitute the largest high mountain- 
group in Southern California, and include the highest peak 
south of Mt. Whitney. The forested area is more extensive 
than elsewhere in Southern California. - ” Furthermore the 
isolation of this mountain-group from any other of approxi¬ 
mately similar altitude affords an attractive feature. 
Mr. Grinnell’s map and sections fully illustrate these points, 
and shew that the Lower Sonoran Zone, the Upper Sonoran 
Zone, the Transition Zone, and at least the two lower divisions 
of the Boreal Zone (of Dr. Merriam) are represented in this 
mountain-range. 
Mr. Grinnell discusses at full length the Plants, Birds, 
Mammals, and Reptiles which he collected, in order to 
establish these views. The Birds, with which we are mainly 
concerned, met with special attention, as might be expected 
from the Editor of f The Condor/ Over 1260 skins were 
collected, as well as many nests and eggs. Of 139 species 
found in the district examined, 48 are believed to be per¬ 
manently resident, 68 are summer visitors, and only 23 are 
transient. 
The following passage contains Mr. GrinnelPs general 
views as to the Avifauna of this mountain-group :—“ The 
Ornis of the San Bernardino Mountains, in common with
