REVISION OF ARDEA HER0DIAS—0BERH0L8ER. 



547 



apparently non-breeding example from the Pacific Ocean at the 

 Mexican and United States boundary hne (No. 133774, U.S.N.M.), 

 taken July 16, 1894, but it seems to belong to this race, notwith- 

 standing that the form from San Diego, Cahfornia, is not the same. 

 No breeding examples from the San Joaquin Valley, or from the 

 southern Sacramento Valley, California, have been available, and we 

 therefore can not determine the summer resident of this region. A 

 single specimen without date, from the Sacramento Valley (No. 9472, 

 U.S.N.M.), is apparently Ardea herodias treganzai, but it is doubtless 

 a migrant or a straggler. 



Altogether, 36 specimens have been seen, from the locaHties given 

 below, breeding records being followed by an asterisk:
