484c'. Perisoreus canadensis nigricapillus vs. F. c. /umi- 

 frons {cf. Howe, Osprey, 1902, 105). 



485. Perisoreus obscurus vs. P. canadensis obscurus {cf. 

 Howe, Osprey, 1902, 105). 



485r/. Perisoreus obscurus griseus vs. F. canadensis {cj. 

 Howe, Osprey, 1902, 105). 



The proposed changes in the above three cases appear to be 

 quite unnecessary. 



Subgenus Picicorvus vs. genus Picicorvus (cf. Coues, Osprey, 

 HI, 1899, 144). Ficicorvus is not considered worthy of full 

 generic rank {cf. Seventh Suppl., Auk, 1895, 167). 



501a, Sturnella magna hoopesi vs. S. m. mexicana {c/. 

 Chapman, Bull. Am. Mus. N. H., XIII, 1900, 298, 303). 

 This form is considered to be sufficiently distinct from S. ni. 

 mexicana to retain its present status in the Check-List. 



550(/. Amniodramus maritimus macgillivraii vs. A. mari- 

 timus {cf. Howe, Contr. Am. Orn., I, 1902, 32). The Com- 

 mittee is unable to find sufficient grounds for reversing its 

 decision in this case. 



622a, h, c. Lanius ludovicianus excubitorides, gambeli, 



and anthonyi vs. Z. ludovicianus {cf. Grant, Novit. Zool. 

 1902, 461). 



No change is considered necessary in respect to the status of 

 these subspecies of Lanius. 



Dendroica montana vs. D. virens {cf. Ridgway, Bull. U. S. 

 Nat. Mus., No. 50, pt. II, 1902, 784). The identification of 

 Wilson's Sylvia montana with Dendroica virens appears to be 

 not without question, and its present position in the Hypo- 

 thetical List is thought to best represent its status. 



713a. Heleodytes brunneicapillus bryanti vs. H. brunnci- 

 capillus and
