Ridgway stated that he had examined 12 females and 1 male of this race, 

 of which he gave the range as "Northwestern Mexico and lower Colorado 

 Valley, in southern California and Arizona; south to Mazatlan." The 8 

 specimens listed above were all available for Ridgway 's use in 1887, but only 

 presumably belong with the form currently known as sonoriensis. 



The type locality was restricted to Mazatlan by Ridgway (Birds of North 

 and Middle America 2: 338, 1902). This means that the lectotype should 

 be drawn from the 5 specimens last listed above, and preferably from the 

 last 4 (females). No. 49771, however, carries a red type label on which 

 Ridgway himself has at some time written "Agelaius phoeniceus sonoriensis 

 Ridgw." For this reason. Camp Grant, Arizona, has been adopted as type 

 locality of sonoriensis, and we find ourselves with a single topotype, im- 

 mature and possibly unidentifiable to subspecies. Ridgway's original re- 

 striction to Mazatlan should again be honored. 



Nos. 4600 and 58285 at some time entered Ridgway's private collection 

 and then suffered loss of their original labels.
