Molothrus ater obscurus (132) is hardly entitled to be numbered 
with the birds of the district, and while Passer domesticus (189) is 
in the numerical list, the introduced species of Phastani are not. 
Owing to absence part of the proofs were not seen by me, and 
hence the following corrections in authorities for names should ‘be 
added to the errata:

THE VARIATIONS OF PLATYSTEMON AND ESCH- 
SCHOLTZIA. 
BY KATHARINE BRANDEGEE. 
In a previous paper* the writer called attention to the extreme 
variability of these western members of the poppy family; the very 
trivial differences upon which it was proposed to divide Eschscholt- 
zia into numerous species, and the fact that Platystemon was sus- 
ceptible of an almost equal amount of splitting. 
Since the date of that paper many forms of these plants have been 
collected, and a portion of them distributed by the California Acad- 
emy of Sciences, in the hope of making our variable species better 
understood. Notes and localities are here given for the more strik- 
ing forms, so that any one having interest in the matter can verify 
readily those already known, and not too hastily believe that a 
“new species ’’ is discovered, because variations from a local type 
make their appearance. 
_ Platystemon Californicus Benth., locally known as Cream-Cups, 
is rather widespread, extending from Oregon southward to Socorro,t 
twenty miles below San Quentin in Baja California. This is 
the southernmost recorded station, but it probably extends con- 
siderably further south along the coast, though certainly not so |
