No. 2376. d ad. Novita, 150 ft., 7.xii.08.— Wing 69 ; tail 62 ; 

 bill 15 mm. 



" Iris dark brown, feet and bill black." 



A second specimen from this region I have seen in Count 

 Berlepsch's collection. It is an adult female, and was obtained 

 by the late Gustav Hopke at San Pablo, 4500 ft. alt., January 21, 

 1897. (Wing 65 ; tail 58.i ; bill 14^ mm.) 



The West Colombian birds agree with a series from Bogota 

 and San Esteban, Venezuela, in size and coloration. Specimens 

 from N.W. Ecuador (Paramba) are also similar. 



All these examples difi'er obviously, however, from L. s. S'lvper- 

 dliaris, of which I have examined a large series from Central and 

 Southern Peru and Northein Bolivia, in the much deeper yellow 

 abdomen, and in having the throat and chest strongly tinged with 

 olive-green. The typical race has the under parts very much 

 paler, about primrose-yellow, with but a slight greenish wash on 

 breast and sides. 



The colour of the apical spots to the wing-coverts is of no diag- 

 nostic value, for it vaiies fi-om primrose-yellow to dull ochreous 

 in individuals taken at the same place. 



While there can be no question as to the distinctness of L. s. 

 superciliaris and L. s. poliocephalus, the status of the third 

 geographical race, L. s. iransandinus Berl. &, Tacz. *, from 

 South-western Ecuador, is not yet definitely settled. Two females 

 in Count Berlepsch's collection are, indeed, much smaller than 

 L. s. poliocephalus ; but the dimensions given I. c. for a male are 

 scarcely inferior to the average measurements of adult males 

 from Colombia and Venezuela. So far as coloration is concerned 

 the two forms are practically identical. 



Another uncertainty exists with regard to the Central Ameri- 

 can birds, wdiich Ridgway and other American naturalists have 

 referred to L. s. superciliaries of Peiai. This, however, can 

 hardly be correct. Either they belong to L. s. polioceijhalus, 

 or they may represent yet another race.
