Some 40 specimens, all from Fort Whipple and all of Coues's collecting, 

 were entered into the museum register prior to publication of the name 

 arizonae; perhaps 35 of these were still in the collection in October 1872, and 

 all must be considered as at least potential cotypes. (Of the 35, 17 now lie 

 before me.) 



Twenty-six specimens taken in the autumn of 1864 were entered into the 

 register in April 1865, apparently by Baird, as "Spizella arizonae Coues" 

 (without a following query) ; so far as members of this series are still in 

 Washington, the same name appears in Coues's hand upon their labels. 



Thirteen others, mostly taken in the spring of 1865, were entered in 

 January 1866 as "Spizella ?"; upon the labels of surviving specimens ap- 

 pears in Coues's hand either " 'arizonae'?" and/or "socialis?." 



Careful study of Coues's diagnosis shows that the cotypes must be adult 

 or subadult birds in autumn plumage — in short, members of the earlier 

 series labeled by Coues himself as arizonae and from which the diagnosis 

 published in 1872 must have been drawn. The series collected in the spring 

 of 1865 does not, of course, fit this diagnosis, since the crown is no longer 

 "grayish-brown streaked with dusky like the back," the black frontlet is not 

 lacking, and there is a "definite ashy superciliary line." To judge from 

 label identifications, the spring-taken series must have caused Coues himself
