1915.] Chapman, New Colombian Birds. 641 
Remarks.— This form is based on a male and female from Peque and a 
male from the vicinity of Medellin presented to the American Museum by 
Francisco Escobar, Colombian Consul-General at New York. Its strongly 
marked characters are particularly well shown by this last-named specimen 
which leads to the conclusiow that the male and female examples “f” and 
“g” recorded by Hargitt (Cat. Bds. B. M., XVIII, p. 549) from Medellin 
as Picumnus granadensis and later identified by Hellmayr (cf. P. Z. S., 
1911, p. 1189) should be referred to this race. 
Of true granadensis I have ten specimens of which two from San Antonio 
may be considered as topotypes; while two others from Los Cisneros may 
be considered equally topotypical of Picumnus canus Bangs (Proc. Biol. 
Soc. Wash., 1910, p. 72) which, as Hellmayr (P. Z. S., 1911, p. 1190) has 
shown, is a pure synonym of granadensis. 
Although in pattern of marking antioquensis approaches the Core 
type, and thus to some extent bridges the wide difference between grana- 
densis and olivaceus, I nevertheless feel that the two forms are specifically 
distinct. : 
The reason for this belief will be given in connection with the treatment 
of the Colombian forms of Picumnus olivaceus in my final report. 
Conopophaga castaneiceps chocoensis subsp. nov. 
Char. subsp.— Similar to C. c. castaneiceps but much darker, wings and tail 
shorter but bill longer; male with the back mummy-brown with an olivaceous cast 
instead of deep neutral gray (with an olivaceous wash in immature specimens); 
crown chestnut instead of Sanford’s brown, this color darker posteriorly but reaching 
as far back as the crown-cap in castaneiceps; underparts dark mouse-gray in place of 
deep neutral gray; the center of the belly whitish, the flanks heavily washed with 
olivaceous. 
Apparently nearer C. c. brunneinucha Berl. & Stolz. of Peru but chestnut of crown 
evidently more extensive and size smaller. Wing, 68; tail, 39; tarsus, 29; culmen 
15 mm. 
Type.— No. 123321, Am. Mus. Nat. Hist., « ad., Baudo Mts. (3500 ft.), Choco 
Colombia; July 18, 1912; Mrs. E. L. Kerr. 
Remarks.— Although I have only the type of this species its characters, 
as compared with C. c. castaneiceps, are so pronounced that I have no 
hesitation in describing it as distinct from that race. Furthermore, I have 
two females from La Frijolera on the western slopes of the Central Andes 
above the lower Cauca which, in being generally darker and in having more 
olive on the flanks, are obviously intermediate between chocoensis and cas- 
taneiceps. A female recorded from La Selva (4600 ft.) on the headwaters
