482 Descriptions of New Species of American Birds. 



shorter and more oval on the upper part of head and neck, and 

 still wider on the breast ; the feet, however, are larger, and the 

 tarsus shorter, so that the former exceed the latter, while in 

 eburneirostris the tarsus is longer than or at least nearly equal to 

 the middle toe and claw ; the shade of reddish brown on wings and 

 tail is lighter, the shafts of tail-feathers are light yellowish rufous, 

 instead of very dark reddish brown ; the chin and upper part of 

 the throat in eburneirostris are uniform clear buif yellow, in the 

 new species these parts are lighter in color, and the feathers are 

 margined with brown, as are those also on the lower part of the 

 throat ; the yellowish of the shaft streaks in the head and back is 

 much paler ; bill pale horn color, clouded ; iris red ; legs dark 

 brown. 



"Length 9.25 ; wing 4.34 ; tail 3.90; bill above 1.70, from nostril 

 1.28, gape 1.67 ; tarsus .88 ; middle toe and claw 1.00, middle toe 

 alone .70. 



" Habitat. — Mexico, Mazatlan. Collected by J. Xantus. ~No. 

 of type, 23,859. 



" Four specimens compared with alike number of eburnei- 

 rostris, show the peculiarities above referred to, in the pale 

 colors, large feet and dusky margins to the feathers of the chin. 



" I find no mention of any Dendromis in Eastern Mexico, 

 north of Cordova or Xalapa, and of none in Western Mexico 

 at all. The present species exhibits a range considerably 

 further to the north than any other of the genus." 



Note. — I recently found in certain families of birds in the 

 collection of the Smith. Institution, several new 7 species, and 

 among others some with MS. names given by Prof. Baird, 

 which I have adopted; these are the five last described in the 

 above paper. Prof. Baird kindly furnished me with his notes, 

 made a few years since when he received the birds, with his 

 permission to use them and to make such alterations as I 

 might deem necessary ; his notes are indicated by quotation 

 marks.
