Museo Naoional de Costa Rica. 



Geothlypis bairdi. 



Four specimens compared with Mr. butting's three examples in the 

 U. S. National .Museum, from Los Siibalos, Nicaragua, are probably- 

 inseparable from that form ; however, the under parts are brighter 

 yellow and the yellowish olive green of the sides does not encroach so 

 far on the sides of the breast and the lower parts in general. In ad- 

 dition, in Mr. Nutting's specimens the under tail-coverts are almost 

 exactly the color of the sides, while in mine they are much more yel- 

 lowish. 



The relative measurements, as shown below, are almost the same.

Basileuteriis delattrii. 



Two young sj)ecimens, both from the vicinity of San Jos^, one in 

 the collection of the U. S. National Museum, the other from the col- 

 lection of the .Museo Nacioiial de Costa Rica, differ from the adult, in 

 being dusky browni.sh olive above, especially on the upper back and 

 head; the lower back, rump, tail, and wings are more as in the adult. 

 On the head there are no signs of the chestnut crown or white super-
