[Compared by Dr. Stolzmauu with the typo of G. unicolor 



Tacz. in the Warsaw University Mnseiim.] 



Through the kindness of Dr. Stolzmann I was enabled to examine speiiintMi 

 No. 3, and fonnd it to agree with tiie female of Godman's Xenoiiipo nubalaris, 

 excejjt that the bill is rather longer and the crown decidedly darker green. These 

 differences, however, are very slight and well within the range of the individual 

 variation to lie observed in the allird species, and I have not the slightest doubt of 

 their identity. It is hardly to be understood iiow Mr. (lodman could associate this 

 bird with XcDOpipo atronitens Cab., to which the male has only a superficial 

 resemblance in being of the same glossy black colour. X. atronifcits is well 

 characterised by its broad, flattened mesorhiuium. C. unicolor, on the other hand, 

 has a much narrower and qnite differeutlj-shaped bill, with the culmen distinctly 

 ridged, like ChloropriJoflaacaiAlUt. The proportions of the wings and tail are the 

 same as in the latter species, with which it also shares the presence of a large tnft 

 of soft silky white feathers on the sides of the breast. In coloration, however, it 

 is altogether different from the other species of Chloropipo, showing the same 

 sexnal difference as Xenopipo atronitens. Mr. Sclatei * put G. unicolor as a synonym 

 of C. uniformis from British Guiana, but Count Berlej-sch and Mr. Stolzmann {I. c.) 

 have already pointed out the differences existing between these two birds. The 

 species has thns to stand in future as Vhlorojiipo unicolor Tacz. It apjiears to 

 be an inhabitant of high elevations. 0. T. Baron collected it near Guayabamha, 

 at an altitude of 4000 to 5500 feet ; Kalinowski obtained his sijecimen at Garita 

 de Sol, 11,000 feet; and Jelski found the type at Amable Maria, a little over 200IJ 

 feet. These localities are the only ones as yet known. 



24. Chloropipo holochlora Scl. 



Cat. Birds Brit. Mus. xiv. p. 287 [type ex Bogotd coll.]. < 



The type in the British Mnseum is perfectly similar to specimens from Eastern 

 Ecuador and N.E. Pern (Chyavetas). The upjier jiarts are of a deep sinning grass- 

 green, the throat, chest and sides of the breast rather duller, more greyish green, and 

 the middle of the abdomen is clear pale yellow. Axillaries and under wing-coverts 

 dull greenish grey. 



The specimen from I'asto f (spec, b of iSdater's list), however, is very diflerent, 

 and agrees in coloration with a large series from various places in Northern 

 Ecuador. I propose to call this form 



Chloropipo holochlora litae n. snbsp. 



Similar to G. It. holochlora, but easily known by having the whole upper 

 snrface pale olivaceous green (instead of deep shining grass-green). 



Type in Mus. Tring : No. 143. " $ " ad. Lita, N. Ecuador, 3ii0n ft., September 

 22, 1899. Collected by Mr. Miketta, one of Mr. Rosenberg's correspondents.

I examined more than 20 specimens from the following localities, all in N.W. 

 Ecuador : Cachabi, 500 ft. ; Ventana ; Lita, 3000 ft. ; Paramba, 35i)(i ft.
