164 Natural History of the Faraliones. [ ZOE 
in May, June, July and August, if they do not nest there. But one 
addition to the list of birds published in Mr. Bryant’s catalogue was 
made, the Carolina rail ( Porzana carolina). A specimen was shot 
by Mr. W. A. Beeman, head light-keeper, in August, 18go, and is 
now in his possession mounted. 
It will not be necessary to detain the reader with a narrative of 
the remainder of the trip, as nothing new in the way of birds was 
discovered. Early on the morning of July 6, we received news that 
the egg boat was ready to return, so after hastily packing we soon 
found ourselves pitching about in a rough sea, en route for San 
Francisco. 
It may be fitting to close this account of the birds of the Farallones 
with a word on their geographical distribution in general. The 
water birds which nest upon these isolated rocks are such species as 
frequent the rocky islands and mainland of the north Pacific, as far 
north as Alaska. Indeed, the Farallones appear to mark the south- 
ern limit of breeding range of one or two species. Mr. Clark P. 
Streator* has noted the tufted puffin, Cassin’s auklet, western gull, 
pigeon guillemot and the three cormorants of the Farallones breeding 
upon the Santa Barbara Islands. Of this number Mr. Bryant, in 
his Catalogue of the Birds of Lower Californiat records Cassin’s 
auklet as breeding as far south as San Geronimo Island (Anthony), 
and the western gull as breeding on Todos Santos Islands off 
Ensenada and upon the Island of San Pedro Martir (Goss). The 
California guillemot I do not find recorded as breeding south of the 
Farallons. All three cormorants are found in Lower California and 
probably all breed from there north to Washington as stated in the 
A: O. U. Check List.{ The ashy petrel has not been recorded, I 
believe, as breeding at any point except the Farallones. The com-
