Two specimens : 



a. 9 , March 8, 1904. 



b. Chichen-Itza, 189- E. H. Thompson. 



My observations on the occurrence of this bird agree with Chapman's, viz., 

 " Rather uncommon. It was found in pairs and trios in the woods, and was 

 rather shy and suspicious." 



MNIOTILTIDAB.

97. *Geothlypsis trichas brachidactyla (Swainson).

Northern Yellow-throat. 



One seen in a milpa near the Sacred Cenote on February 27, and another 

 along the Xmakaba road on February 28. No specimen was taken, but it is 

 probable that these birds belonged to this subspecies (cf. Ridgway, Bull. 50, 

 U. S. Nat. Mus., 1902, 2, p. 665).
