Type, No. 154835, ¢ ad., U. S. Nat. Mus., Biological Survey Collection. 
Coatzacoalcos, Vera Cruz, Mexico, April 15, 1896, E. W. Nelson and E. A. 
Goldman. 
Distribution. — Southern half of Vera Cruz, Tabasco, and bordering 
part of Chiapas. 
Subspectfic characters. — Smaller than AL dudbius with broader white 
frontal area and rather broader white barring on dorsal surface; sides 
and lower part of head, neck, and body darker, more brownish gray; 
crissum more heavily barred with black. 
Dimensions of type.— Wing, 124; tail, 76; culmen, 29; tarsus, 23. 
General Notes. — This form inhabits a region of much greater 
humidity than that of typical JZ. dubius and a specimen from the 
heavily forested region of Chiapas is darker than Vera Cruz 
birds and probably represents the extreme of the form in this 
respect.
