both birds shows that Dr. Hartert is probably correct in his view 

 of the status of the American bird. The latter differs from Astur 

 gentilis in its more mottled or irregularly barred lower parts; but 

 individual variation in each of the two races bridges this difference. 

 The American Goshawk is certainly a very distinct form, but is 

 best regarded as a subspecies of the European bird. The two 

 American subspecies should therefore be called Astur gentilis atri- 

 capillus (Wilson) ; and Astur gentilis striatulus Ridgway. 



Regulus satrapa Lichtenstein. 



Mr. C. E. Hellmayr some time ago 1 considered the American 

 Golden-crowned. Kinglet a subspecies of the European Golden- 

 crested Wren {Regulus regulus). Recent comparison of a series 

 of specimens of both shows that this is undoubtedly the rela- 

 tionship of the two birds, for, although their ranges are entirely 

 separate, being cut off by the Atlantic Ocean, thej^ are fully con- 

 nected by intermediate individuals, and, therefore, from a modern 

 standpoint are, of course, subspecies. As there is no question 

 regarding the subspecific relationship of the Western Golden- 

 crowned Kinglet {Regulus satrapa olivaceus Baird), our two Golden- 

 crowned Kinglets must now stand as Regulus regulus satrapa 

 Lichtenstein, and Regulus regulus olivaceus Baird. 



Passerella iliaca altivagans Riley. 



The Fox Sparrow described by Mr. J. H. Riley as Passerella 

 iliaca altivagans, 2 from the Moose Pass Branch of the Smoky River, 

 Alberta, has been discredited by most subsequent authors. Further 

 study of this bird, however, shows that it is a good form, most 

 closely allied to Passerella iliaca, but differing in its more rufous 

 upper parts, including the outer webs of the secondaries and ter- 

 tiaries and of the tail ; and in the more ruf escent spots on the lower 

 surface. From other races of Passerella iliaca it is so different as
