parative distribution of the birds of the Farallones with reg^ard to 

 their breeding range may be graphically represented as follows:

Northern U. 8. 



. Ashy Petrel I FABALLONS. 



Santa Barbara Isls. 



Lower California. 



MAMMALS. 



As might be expected there are no land mammals native to the 

 Farallones. Rabbits have been introduced and have multiplied 

 until they are extremely abundant and very tame. They are of 

 every imaginable shade of color from black, through brown and 

 gray to white, sometimes clear, frequently mottled. During the 

 dry season, the light-keeper informs me, they die off in great num- 

 bers owing to lack of food. 



Sea Lions ( Eiimetopias stelleri), are common, especially upon 

 the North Farallones. Mr. Beeman informs me that fur seals 

 ( Callorhimis ursiyius), occasionally visit the islands during the win- 

 ter months and also the leopard seal ( Phoca vitulina). 



Note. — There are two more species which were overlooked and 

 which should be added to the list of California water birds published 

 in this issue. 



NuMENius BOREALis (Forst.) Recorded from San Diego by 

 Mr. Holterhoff. (Auk, i, 4, 393.) 



Xema sabinii (Sab.) A specimen (No. 379; is in the collection 

 of the California Academy of Sciences. It was taken on San Fran- 

 cisco Bay in October, 1889, and was identified by Mr. Belding.
