and, moreover, he leaves the locality doubtful (" cspece ([ui parait habiter le 

 BresU I ") ; bat there seems to be no other species to which we can refer his name : 

 it seems too small for C. daphne, the tail not emarginate enough for C. aubfurcatus, 

 the beak difFerentl}' coloured from that of C. imcherani. I therefore agree with 

 Elliot, Salvin, and others that the name of Lesson should stand for the species under 

 consideration. Very few are the specimens in collections from Brazil. The specimen 

 from Barcellos on the Rio Negro {Agtjrtria mflipkila Natt., in Pelz. Orn. Bras. 

 pp. 29, 57) has a bluish throat, and therefore would belong to C. daphne. A skin 

 in Count Berlepsch's collection which is jirobablv from the middle parts of the 

 Amazons, though its locality is not known with certainty, belongs to C. prasiiuu<, 

 and has not at all the more forked tail of C. subfurcatus, but it is slightly more 

 bluish on the breast than other C. prasimis usually are. It is almost certain that 

 in some parts of Brazil intermediate forms between ('. daphne and C. siibfureatux 

 are found, and they may even be enough localised to make them into another inter- 

 mediate subspecies. It is also not impossible that connecting links e.xist between 

 C. subfurcatus and C. prasiuus, but at present we do not know them. Specimens 

 from Pern (C. daphne') are perhaps generally a little smaller, with shorter beaks, 

 than tliose from Ecuador {€. napensis), but they seem rather variable, and I have 

 not enongli evidence to separate these two forms conscientiously. 



There has always been some tuicertainty about Chlorostilhon {Pawjchlora') 

 euckloris, which is the same as P. poortmani major Berlepsch. I have, therefore, 

 studied Count Berlepsch's types and many other specimens in the collections at 

 Berlepsch, Tring, Loudon, and Paris. There is no doubt that the skins from 

 Bucaramanga in the state of Santander, the typical C. euckloris, are very different 

 from typical C. poortmani, especially in their long beaks ; but in Bogota collections 

 we find, besides a vast number of typical C. poortmani, certain skins forming 

 complete intergradations between the two forms, and some typical C. euMoris as 

 well. G. euchloris must therefore be degraded to subspeciiic rank. 



Boncard, in the Ilumming-Bird, 1892, p. 79, and Gen. Humm. B. p. 122, 

 described a C. speciosus. The tj^^e, with its dull oily, somewhat bluish or gre}ish 

 underside, is a very distinctly and curiously coloured Bogota skin, agreeing in its 

 dimensions with C. angustipennis. It is at present impossible to say whether it 

 belongs to a different species, or whether it is a dark-coloured variety of C. angusti- 

 pennis. Boucard, Gen. Humm. B. p. 120, described also a C. iviedi {rom Brazil. It 

 is exactly like C. pucherani, but a little less bluish on the throat than most skins of 

 €. jyueherani, and more golden aliove. The less strong blue tint on the throat 

 seems to be of no consequence, as it varies considerably in the species, and there are 

 undoubted skins of < '. pucherani which have as little blue as Boucard's ('. u-iedi. 

 The more golden hue is, in my opinion, not a specific character, but due to age of 

 plumage. When in the Dutch West Indian Islands, Aruba, Curacjao, and Bonaire, 

 my wife and I collected a large series of C. caribaeus (the C. atala of the Catalogue 

 of Birds). They were mostly glossy golden green, as we see them in every collec- 

 tion, but a few freshly moulted birds shot in the last time of our stay showed a 

 most surprisingly strong golden sheen on the abdomen and above, and the crown 

 was really jmre shining gold. Most of these had a few old feathers left, but one in 

 just perfected plumage is faultless and of great l)eauty. In view of this experience 

 of my own I cannot attach any specific value to a more golden gloss in single 

 individuals from no distinct locality, and I regard C. wiedi without the slightest 

 hesitation as merely a synonym of C. pucherani.
