the middle of the abdomen, and the much darker flanks and 

 under tail-coverts ; the dark shaft-lines on the head are 

 almost obsolete, and the measurements are larger. 



Total length 198 mm., exposed culraen 14, wing 94, 

 tail 90, tarsus 30, middle toe with claw 25, hind toe with 

 claw 20. 



This form can very well be separated subspecifically under 

 the above title. 



The Monte Video bird is much paler on the under 

 surface, the grey on the sides of the face also paler. 



The female, of the two birds which were collected by 

 Mr. O. V. Aplin at Santa Elena, Soriano, on the 14th of 

 March, 1893, is quite a different-looking bird from E. pla- 

 tensis, being more yellowish green on the upper surface ; the 

 black shaft-lines on the top of the head, so conspicuous in 

 the Argentine bird, are scarcely discernible, and the shaft- 

 streaks on the back very much narrower and inconspicuous. 

 The under surface is almost entirely buff with only a tinge 

 of grey on the throat, the buff becoming darker on the 

 flanks. 



Total length 208 mm., culmen 14, wing (imperfect) 

 fourth primary 90, tail 93, tarsus 28, middle toe with 

 claw 26, hind toe with claw 20. 



The male, which was collected on November 3, 1892, is 

 similar to the type from Maldonado, but inclining to grey 

 on the thighs and somewhat paler on the under tail-coverts.
