birds collected by Richardson at Barbacoas. In general coloration and 

 pattern of marking they can be matched by specimens from western Colom- 

 bia and Panama which I identify as T. m. ruficeps, but they have a well- 

 developed occipital crest, which, with the entire crown, is sooty black in one 

 (labelled "male") and black barred with chestnut in the other (labelled 

 "female?"). Both have the ear-coverts dusky, the cheeks, sides and back 

 of the nape barred with or looped with black and tawny-ochraceous. This 

 is obviously a representative form of T. m. ruficeps with which it nearly 

 intergrades by individual variation alone.

Found only in the Temperate Zone. A Laguneta specimen, which, 

 unfortunately, is not sexed, has the back, wing-coverts, rump and upper 

 tail-coverts conspicuously barred, and so far as comparison with faded 

 material permits of accurate identification, appears to be essentially typical 

 of Julius. A specimen from the Western Andes which is labelled " female, 

 ovaries slightly enlarged," resembles the Laguneta specimen in size and in 

 general color, the throat being pure white, the forehead and crown hazel- 

 chestnut, but the back, rump, wing-coverts, upper tail-coverts, flanks, and 

 under tail-coverts are finely and almost uniformly vermiculated with black, 

 and the ochraceous spots conspicuous on the wing-coverts and secondaries 

 of the Laguneta bird are barely evident on the greater and median coverts. 



In its absence of barring, this bird is unlike any example of Nothocercus 

 Julius which I have seen. It may possibly be referable to N. nigricapillus, 

 with the description of which it agrees except for the absence of black and 

 white blotches on the wings and underparts, its brown head and more 

 reddish forehead.
