The specimen here described was sent to the U. S. National Museum 

 several years ago by Mr. Frank B. Armstrong, who collected it at 

 Alta Mira, Mexico. Over twenty skins of Bendrornis flavigaster, 

 obtained at the same place, were also received, but none of them shows 

 any approach to this apparently new species. It is in general similar 

 to D. flavigaster, but differs in having the throat and malar patch 

 streaked instead of uniform buff, these markings, as well as those of 

 the remainder of the underparts, beiug for the most part dentate, rather 

 than oblong; the under wing coverts are variegated, not uniform. That 

 these characters are not those of an immature stage of D. flavigaster is 

 shown by several young examples of the latter collected in Mexico by 

 Mr. E. W. Nelson (Biological Survey collection), in which the pattern 

 of coloration is similar to that of the adults. 



The new species may be described as 



DENDRORNIS STRIATIGULARIS, new species. 



Type.— Gat. No. 135157, U.S.N.M.; female adult, Alta Mira, Tamau-
