But we have had the pleasure of receiving safely the first 
four numbers for this year, in which we find much of in¬ 
terest to Ornithologists, though of course specially to such 
of them as reside in the Western United States. The 
illustrations in the text are numerous and in most cases 
excellent. 
We cannot mention all the contributors to these numbers, 
but may call attention to Mr. Austen's observations on the 
birds of the little State of Morelos in Southern Mexico and 
to Mr. Hanna’s account of the nesting of the White-throated 
Swift (Aeronautes melanoleucus) on Stover Mountain in 
California as worthy of study. Mr. Wright's account of his 
Ornithological Trips to the Coronados Islands is well illus¬ 
trated. The review of the u Mammals and Birds of the 
Alexander Expedition to Alaska in 1907 " seems to shew 
that the results of the expedition were of special interest. 
The specimens of birds obtained were 512 in number, among 
which are six described as representing new species or 
subspecies. We have not yet been so fortunate as to see 
this volume, which has been lately published by the University 
of California's new Museum of Vertebrate Zoology.

the Field Museum of Chicago's last expedition to British 
East Africa (1905-7) under the direction of Mr. C. E. Akeley. 
A map shews the various localities where the specimens 
were obtained. Their number is not exactly stated, but 
they are referred by the author to 228 species, of which 
one (.Alethe akeleyce from Mount Kenya) is described as new. 
Most of the species are well known.
