2. Haematopus niger Pall. 



A few of these birds found here. 



3. Phalacrocorax penicillatus (Brandt). 



Very abundant here, at Cerros, and several intervening i^oints. 



2, San Quentln Bay, ivest coast of Lower California, latitude about 30'^ 23'. 



I arrived at this place May 2, and remained until the 11th. Much of 

 the bay is shallow, consequently at low-tide very extensive mud flats 

 are exposed, making this a favorite resort for water birds, Avhich upon 

 our arrival were very abundant, but previous to May 11 most of them 

 had taken their departure for their northern breeding grounds. So tkr 

 as observed, the hind birds of this locality are about the same as those 

 found in the vicinity of San Diego. 



1. Harporhynchus redivivus (Gamb.). 



Eare; apparently the same as the San Diego bird. [No specimens.] 



2. Thryomanes bewicki spilurus (Vig.). 

 Not comuion. 



3. PassercnliLS anthinus (Bp.). 



Very common in grassy meadows ; probably resident here and at San 

 Diego. 



4. Melospiza fasciata samuelis Baird. 



But one individual noticed. This was found in tules by a pond of fresh 

 water. 



5. Pipilofuscus crissalis (Vig.). 



Specimens shot but not preserved appeared to be identical with others 

 shot at San Diego in April and May.
