their breeding range may be graphically represented as follows:

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 (Zumetopias stelleri), are common, especially upon 
the North Farallones. Mr. Beeman informs me that fur ‘seals 
( Callorhinus ursinus ae occasionally visit the islands during the win- 
ter months and also the leopard seal ( Phoca vitulina ). 
Norr.—There are two more species which were overlooked and 
which should be added to the list of California water birds published 
in this issue. ' ney
