Description taken from a specimen in the collection of the Academy of 

 Natural Sciences of Philadelphia from Chiquitos, the locality of Lafres- 

 naye's type. 



This species is apparently distinct from the other members of 

 Dendromis from the fact, that the buff stripes on neck, upper 

 part of back, and underparts are not margined with black. No 

 other species is known so far as I am aware, that has not these 

 spots or stripes margined with black, upon some one or other 

 portion of the back or underparts. This character is especially 

 emphasized by its describer, who states that "ses Jlammettes ne 

 sout nulle?nciit circouscrites de noir ou de noir&tre stirles par- 

 ties anterieures ct sur le dos." — Five specimens are before me, 

 which I assign to this species, three of them are from the 

 collection of the Philadelphia Academy of Sciences, and two from 

 Matto Grosso in the collection of the American Museum of Natural 

 History in New York. One of these last, No. 33,650, has on 

 two of the feathers of the neck, a narrow black margin to the cen- 

 tral buff stripe, but the other, No. 33,649, is entirely without black 

 margins. The underparts on all the examples are more olivaceous 

 than those of specimens of either D. rostripallensox D. guttata, 

 which have a very decided reddish tinge. In a large series of speci- 

 mens it would not be unlikely, I think, to find some with more or 

 less black margins to the buff stripes on the back, but the fact that 

 these stripes on the entire underparts are without these black 

 margins readily distinguishes d'orbignyanus from rostrifiallcns, 

 which has the breast stripes margined with black, and from gut- 

 tata, which has all the stripes on the underparts margined in the 

 same manner.
