Jan., 1917 THE SUBSPECIES OF HESPERIPHONA VESPER TINA 19 



Nomenclature that the subsequent action of the author himself in designating a 

 type cannot affect the original tj^peship, and that the ''recognizable published 

 figure" occurring in the same work as the original diagnosis must be accepted 

 as pertaining to the real type. In this case the locality and museum number an 

 plainly stated (Baird, Brewer and Ridgway, 1874, pi. xxn, fig. 4) as "Mex., 

 35150." What is still more noteworthy in this connection is that this is also the 

 only actual specimen of montana referred to in the whole work. Although the 

 nomenclatural points here involved may not be exactly covered in the more recent 

 International Code, American ornithologists will doubtless agree in abiding by 

 the A. 0. U. Code in so far as the latter is not in conflict with the International 

 Code. 



I regret to say that it is impossible with the material and information in 

 hand to satisfactorily define the breeding ranges of the various races of Hcsperi- 

 phona vcspcrtina here pointed out, The majority of the specimens are winter 

 birds, very probably a greater or less distance out of their summer habitat, The 

 breeding ranges indicated under each heading must be considered largely hypo- 

 thetical. Even the breeding area of the eastern H. vespertina vcspcrtina has 

 never been outlined ; nests and eggs of that form remain unknown. To the best 

 of my knowledge authentic eggs of any form of Evening Grosbeak have been 

 found only in California, Arizona and New Mexico. 



Hesperiphona vespertina vespertina (Cooper) 

 Eastern Evening Grosbeak 



Type locality. — Sault Sainte Marie, Michigan (Cooper, Ann. Lye. Nat. Hist. 

 N. Y., i, 1825, pp. 220-222). 



Diagnosis. — Bill relatively shortest and thickest as compared with all the 

 other subspecies; nearest like brooksi, but distinctly shorter, though basal thick- 

 ness about the same. Color-tone of body of male relatively dark, though not as 

 dark as in brooksi. Frontal yellow bar of male averaging widest, as compared 

 with all other subspecies ; nearest brooksi and warreni. Color-tone of both upper 

 and under surface of female averaging decidedly more grayish, less brownish, 

 than in any of the other subspecies; top of head and back not so blackish as in 

 brooksi, and less brownish than in calif ornica, ivarreni, and montana. 



Summer range. — Probably restricted to central portions of Canada east of 

 the main divide of the Rocky Mountains: Alberta (Preble, N. Amer. Fauna no.
