Hahitat. Mexico (A. Salle). Type in Mns. Smithsonian 

 Institution, No. 29693. 



RemMvl^s. This specimen was received from Mr. Salle and 

 labelled by him " Z. aJhifrons, Bp.;''^ the reverse side of the 

 lable is marked " 6 P. ^- J"in, '59." It no doubt was super-' 

 vised by Bonaparte, as Salle's birds mostly were; it is very 

 distinct from the species, whicii is now admitted to be entitled 

 to bear that name, viz., the bird for some time known as L. 

 hrachyptera^ Gray. 



I found this specimen in the collection of the Smithsonian 

 Institution (where there are numerous specimens of the true 

 L. alhifrons) about two years ago, and hesitated to describe it 

 as new, fearing to add to the confusion attached to the name of 

 alhifrons. In general coloration it somewhat resembles that 

 species, which differs in being of a lighter olive above and 

 more roseate on the breast, it has a much longer tail, with no 

 plumbeous on the croM-n, and may be known from all its allies 

 by the inner webs of the primaries being just edged with pale 

 cinnamon. 



L. plumleiccps, Scl. & Sal v. (P. Z. S., 1S68, p. 59), differs in 

 being dark brown above, in having tlie plumage of the breast 

 somewhat darker, and the under-lining of the wings of a more 

 intense color ; in the new bird the plumbeous is confined 

 to tlie crown, and does not extend on the hind neck, as in L. 

 plumbeiceps. 



It really comes nearest to L. rif axilla^ from South America, 

 in general coloration, but that species has the breast more roseate, 

 the blue of the head lighter and more restricted, the sides of 

 the head cinnamon color, and the feet smaller.
