The bird described by Pelzeln as Dendrocincla minor ^ from San 

 Vicente, Matto Grosso, Brazil, which has hitherto remained unidenti- 

 fied, is undoubtedly the same as that previously called atrirostris by 

 Lafresnaye. This is evident from a comparison of the original descrip- 

 tion of minor with the types of atrirostris, which shows a perfect agree- 

 ment both in dimensions and other characters. Furthermore, San 

 Vicente, the type locality of minor, is in southwestern Brazil, not far 

 from Guarayos, Bolivia, whence came the first specimens of atrirostris. 

 This species appears to have a limited distribution, being kno\^^l from 

 only eastern Bolivia and Matto Grosso, Brazil, for all citations of 

 atrirostris from Ecuador and Colombia belong elsewhere.

Type Locality. — Omoa, Honduras. 



Geographical Distribution. — Southeastern Mexico (Vera Cruz) and 

 Guatemala to Panama. 



One of the most conspicuous forms of the genus. In a general way 

 it resembles Dendrocincla atrirostris, but may at once be distinguished 

 by its immaculate buffj^ or ochraceous buff chin, in sharp contrast to 

 the color of the breast; by the color of the outer webs of the'second- 

 aries, which is tawny or bright tawny-rufous, unique in the genus and 

 strikingly different from the olive-brown of the wing-coverts or the 

 dark fuscous of the tips of the wing-quills ; by a much shorter tail ; as 

 well as by other less obvious characters. Birds from Panama are not 

 distinguishable either in size or color from those of Nicaragua or even 

 the States of Tabasco and "\"era Cruz, Mexico; but those examined 

 from Guatemala are rather paler, though not sufficiently so to warrant 

 either their separation or their reference to typhla. 

 Dendrocincla anabatina typhla, subsp. nov. 



Chars, subsp. — Similar to Dendrocincla anabatina anabatina, but 

 decidedly paler throughout, particularly on the lower surface. 



Geographical Distribution. — States of Yucatan and Campeche, 

 Mexico. 



Description.— Type, male adult, No. 167,499, U. S. N. M., Biological 

 Survey Collection; Puerto Morelos, Yucatan, Mexico, March 12, 1901;

Upper parts deep reddish raw-umber brown of decidedly olive shade, 

 rather more rufescent on pileum, where the darker edges of the feathers 

 produce an obscurely squamate effect, paler on rump, and passing into
