^°|-^^'] Thirteenth Supplement to the A. O. U. Check-List. 42 1 



1902, 105). A trinomial appears best to express the status 

 of this form, although actual intergradation is difficult to 

 prove. No change is deemed desirable at this time. 



425. Aeronautes melanoleucus vs. A. saxatilis {cf. Coues, 

 Key, 1903, 557). 



The name saxatilis was originally rejected on account of insuffi- 

 ciency of description ; no change appears to be necessary. 



Myiarchus crinitus residuus Howe, Contr. Amer. Orn., I, 

 1902, 30. (yCf. Nelson, Proc. Biol. Soc. Wash., XVII, 30, 

 March 10, 1994.) 



Rejected, as being too close to AI. crinitus. 



Subgenus Etnpidias Cabanis {cf. Coues, Key, 1903, 522). 

 Not considered worthy of recognition. 



456. Sayornis phoebe (Latham) vs. Etnpidias phcube {cj. 

 Coues, Key, 1903, 525). No change is required. 



Subgenus Mitrephanes Cov's.'s, {cf. Coues, Key, 1903, 532). 



Mitrephayies was originally applied to a group of extra-limital 

 species, and Nos. 470 and 470^ of the Check-List have 

 been erroneously referred to it. 



49L Nucifraga columbiana (Wilson) vs. Picicorvus colum- 

 Inafius {cf. Coues, Key, 1903, 490). This case was decided 

 at a former meeting of the Committee, and no further action 

 is considered necessary. 



Subfamilies SturnellincB, Agelceince, Icterince, and QuiscaiincB {cj. 

 Coues, Key, 1903, 464). These proposed subfamilies of the 

 Icteridae adopted in the ' Key,' seem distinct enough when 

 North American members of the family alone are considered, 

 but they merge into each other through the many intermedi- 

 ate links in tropical America.
