Grant is led to remark that "the striking differences shown in 

 Gould's plate are probable improvements on nature, and the 

 chestnut band which commences behind the eye and crosses the 

 ear-coverts in his figure no doubt really represents the super- 

 ciliary stripe." He remarks also: "I have not the slightest 

 doubt that the bird from 'San Carlos in Central America' which 

 formed the type of Lesson's 0. leucopogon was merely a rather 

 white-throated example of this species." Gould says: "I am 

 indebted to the Baron de la Fresnaye for the use of the specimen 

 from which the above characters are taken; it is the only one 

 that has come under my notice." Now, there is a specimen in 

 the Lafresnaye Collection (No. 7265), at present deposited in 

 the Museum of Comparative Zoology at Cambridge, Massa- 

 chusetts, which is an exact counterpart of Gould's plate, and is 

 almost certainly the original from which it was drawn. It is 

 certainly a very peculiar bird, with its pure white throat, white 

 front and superciliaries, and dull brownish red postocular stripe. 

 The breast is much duller (snuff brown) than in the Panama 

 specimens, and the white spots are fewer. The crest is darker 

 (mummy brown), and the nape rusty rather than buffy, but 

 otherwise the upper parts are the same. 



Whether this white-throated bird represents a color-phase of 

 E. leucopogon, comparable to those of E. sonnini, or is a distinct 

 species with a definite range, I am not prepared to say, preferring 

 to await the receipt of further specimens and the re-examination 

 of Lesson's type. Meanwhile I accept the name leucopogon for 

 the bird from western Panama on the basis of the original descrip- 

 tion, waiving for the time being the question of the type-locality. 

 The two males examined differ from the other forms of this group 

 in having the throat distinctly and rather abruptly bicolor, the 

 upper half white, the lower half antique brown; the forehead, 

 crest, malar, and loral regions are also white. The upper parts 

 are dark as compared with the allied races ; this is not only because 

 of the darker color of the ground-color itself, but also because 

 of the prevalence of dark markings. Females, too, are very dark 

 above, and heavily marked below. 



Arce secured at least three specimens of this form in Veragua, 

 presumably from the vicinity of Calobre. The Agua Dulce
