1915.| a Chapman, New Colombian Birds. 645 
Remarks.— Miller and Boyle collected five specimens of this strongly 
marked form at the type-locality and the succeeding month Anthony, 
Richardson and Ball took nine more at Tacarcuna in eastern Panama. The 
latter series, as a whole, is somewhat paler but is clearly not separable from 
the Colombian bird. Of nigricauda I have two west Ecuador specimens. 
Automolus fumosus Salv. & Godm., known from one Chiriqui specimen, 
appears to be an intermediate between nigricauda saturatus and A. verepacis. 
Judging from the description alone it is nearer the former above and the 
latter below. Wholly aside from other characters its black tail distinguishes 
saturatus from A. rufipectus and A. cinnamomergula. 
Manacus vitellinus milleri subsp. nov. 
Char. subsp.— Similar to M. v. vitellinus (Gould) but male with the throat, breast, 
sides of the head and nape chrome rather than cadmium, posterior underparts olive- 
yellow rather than warbler-green; female paler below, the abdomen, particularly 
centrally, yellower. 
Type.— No. 133857, Am. Mus. Nat. Hist.,  ad., Puerto Valdivia (alt. 360 {t.), 
lower Cauca River, Antioquia, Colombia; December 16, 1914; Miller and Boyle. 
Range.— Probably humid portions of the Tropical Zone of the lower Cauca and 
Magdalena Rivers. Specimens from ‘Cauca, Remedios” recorded by Sclater and 
Salvin (P. Z. S., 1879, p. 517) as M. vitellinus, should doubtless be referred to this 
race. 
Remarks.— Of this well-marked form Miller and Boyle secured an ex- 
cellent series of seven males and five females at the type-locality which 
show, on comparison with a large series of vitellinus, that the characters 
attributed to the new form are constant. | 
The point to which its differentiation has been carried 1s all the more 
surprising when it is found that ten specimens collected by Miller and Boyle 
at Dabeiba and Alto Bonito in almost the same latitude as Puerto Valdivia, 
but on the western slope of the Western Andes, are typical of vitellunus. It 
is even more surprising to find that four males from the Cauca Valley, the 
fauna of which appears to have been derived through the course of the 
Cauca River, are referable to vitellinus rather than millerc. 
I have named this strongly characterized race for Mr. Leo E. Miller, 
leader of our expedition to Antioquia, in recognition of the service he is 
rendering science through his continued explorations in South America. 
Phyllomyias griseiceps cauce subsp. nov. 
Char. subsp.— Similar to P. g. griseiceps (Scl.) but upperparts much darker, the 
back olive washed with blackish and not clearly defined from the crown, size larger. 
Type.— No. 109025, Am. Mus. Nat. Hist., oc ad., Miraflores (alt. 6400 ft.), E. 
of Palmira, Cen. Andes, Cauca, Col.; Chapman and Richardson.
