This latter species differs from Certhia familiaris Linnaeus princi- 

 pally in its shorter, more curved hind claw and its longer bill. The 

 color differences assigned by Dr. Hellmayr for these two species do 

 not always correlate with the structural characters. There seems 

 to be some mistake in this allocation of the American forms, since 

 Certhia familiaris americanais very closely allied to Certhia familiaris 

 familiaris of Europe, and, judging by the shape and size of its 

 hind claw and bill, certainly conspecific. All the American forms 

 are well known to be certainly but subspecifically different from 

 Certhia familiaris americana, and, therefore, all should be regarded, 

 as they formerly have been, subspecies of Certhia familiaris 

 familiaris. 



Penthestes carolinensis (Audubon). 



In a revision of the Paridfe, published a few years ago, 1 Dr. 

 C. E. Hellmayr relegated Penthestes carolinensis (Audubon) to 

 subspecific rank under Penthestes atricapillus (Linnseus). A close 

 study of these birds in life and in the cabinet indicates that this 

 view of their relationship does not best represent the facts; for, 

 while the characters of plumage and of size separating them are 

 relatively slight, these are likewise relatively constant, and it is 

 possible to identify all normal specimens. Their songs, or rather 

 love notes, are radically different in quality and form and can 

 never be mistaken. Furthermore, wherever their breeding ranges 

 meet or overlap, as they do in places in the eastern United 

 States, particularly in the southern Allegheny Mountains, both 

 birds remain just as distinct in all respects as elsewhere. Hence 

 they should evidently be considered distinct species. 



Dendroica coronata hooveri McGregor. 



This race of the Myrtle Warbler was originally described by Mr. 

 R. C. McGregor 2 from a specimen taken at Palo Alto, California. 

 Most subsequent authors, however, with the exception of Dr.
