Geothlypis flaviceps, sp. nov. 

 Yellow-headed Warbler. 



Type, No. 158741, $ ad., U. S. National Mus., Biological Survey Coll.. 

 From Alta Mira, Tamaulipas, Mexico. Collected April 20, 1898 by 

 E. W. Nelson and E. A. Goldman. 



Distribution. — Tule marshes along coast lagoons near Tampico in 

 southern Tamaulipas and northern Vera Cruz, Mexico. 



Description of type. — Color: A broad black mask from bill to line 

 back of orbits on crown and thence down over cheeks and ear coverts 

 to sides of neck ; rest of top and sides of head and nape distinctly yellow, 

 slightly washed with olive green posteriorly. Back, including upper 

 surface of wings and tail olive green. Entire lower surface almost uni- 

 form gamboge yellow, only a little duller on flanks. 



Dimensions of type. — Wing, 60; tail, 56; culmen, 15 ; tarsus, 21. 



Remarks. — This species is closely related to Mr. Ridgway's. 

 G. flavovelatus, also described from Alta Mira, but may be distin- 

 guished at once from that species by its larger bill, greater 

 extent of yellow on top of head and deeper yellow under surface. 

 The type of G. flavovelatus was taken in December and was 

 probably a migrant from farther north while my specimens were 

 taken in April and May and were undoubtedly resident birds. 

 Dimensions of G. flavovelatus: Wing, 53; tail, 54; culmen, 12; 

 tarsus, 21.

BY HARRY C. OBERHOLSER. 



This very homogeneous group of Coerebidae has by some 

 authors been called Ccereba, by some Caereba, by others Arbelo- 

 r/iina, but unfortunately none of these names is properly appli- 

 cable to the genus. As Mr. Ridgway has already shown ! the
