rower (nearly obsolete in some females) ; yellow and white of

2 New species. Although Mr. Lawrence mentioned both Tres Marias and Socorro specimens in his original 
description of Parula ineularis, his description and measurements were taken from a specimen from the former 
locality, which may, therefore, be considered the type. With the same material before me as that which Mr. 
Lawrence examined, I am able to appreciate readily the differences of plumage which he pints out as dis- 
tinguishing the birds from Socorro. In fact, I am somewhat surprised that he considered them the same 
species. The Socorro bird is, upon the whole, more different from C. insularis than the latter is from C. nigri- 
lora.
