PHAETHORNIS OSERYI. 



D'Osery's Hermit. 



Trochilus Oseryi, Bourc. et Muls. in Ann. Sci. Pliys. &c. de Lyon, May 7, 1852 



Ametrornis Oseryi, Reich. Auf. der Col., p. 14. 



Orthornis oseiyi, Bonap. Rev. Zool. 1854, p. 249. 



Ph(ethornis villosus, Lawr. in Ann. Lye. Nat. Hist. New York, vol. vi. p. 259. 



What could have induced the late Prince Charles Bonaparte and Dr. Reichenbach to separate this bird 

 generically from the genus Phaethorms I know not. Certain it is that nothing could be more fallacious, or 

 better calculated to bring science into contempt. No excuse can, indeed, be offered for their so doing, since I 

 believe that neither of them could have personally examined the bird, but that they proposed their generic titles 

 from the mere descriptions of the species : had they ever seen it, they would have compared it with my 

 P, hispidus, and perhaps questioned if the two species were not one and the same ; instead of which they 

 have made hispidus generically distinct, under the name of Ptyonornis, — at least, Dr. Reichenbach has done so. 

 It is such measures as these which give the monographer so much trouble in unravelUng the confusion they 

 have made, and impose upon him the unpleasant task of pointing out such gross errors. I should not have 

 spoken thus strongly on the subject had there been the slightest perceptible difference in form between this 

 bird, the P, super ciliosus, P. Eurynome, and other species which these authors admit are typical Phaethorni. 

 For the separation of the smaller members of the genus under the subgeneric title of Pygmorms proposed 

 by Bonaparte, and Eremita by Reichenbach, some excuse may be made, those little birds forming a very 

 natural subdivision, although, as will be seen, I have retained them all under the generic name oi Phaethorms. 

 We now come to more important points with regard to this species — the country it inhabits, and whether it 

 be or be not identical with P. hispidus, a name published six years prior to that of Oseryi, 



The native habitat of Osery's Hermit is that portion of the Andes lying between Bogota and Ecuador. 

 I have specimens from both these countries now lying before me, — one received in an ordinary collection 

 from Santa Fe, and another from Archidona through the kindness of Professor Jameson. I am also indebted 

 to Mr; Lawrence of New York for another example, which was collected by Mr. Moore in Ecuador. 

 Mr. Lawrence, on comparing his specimens with my Plate of P. hispidus, came to the conclusion that they 

 were distinct from that species, and being unaware that the bird had been described in Europe under the 

 name of Oseryi, proposed for it the specific term of villosus. I agree with Mr. Lawrence that there are suffi- 

 cient grounds for considering it distinct from the P. hispidus, that bird being of a larger size, and having the 

 feathers of the throat of greater length and more distinctly margined with grey, while the lengthened grey- 

 ish-white throat-mark seen in all my specimens of Oseryi is wanting in hispidus. This latter species also 

 inhabits a different country, being, so f^u' as we yet know, only found in the southern country of Bolivia, 

 where it doubtless represents the Oseryi of more northern latitudes. 



M. Bourcier has dedicated this species to the Count d'Osery, the unfortunate " compagnon de voyage" 

 of the Count de Castelnau. 



Head, upper surface and wing-coverts bronzy green, browner on the head; ear-coverts dark brown, bor- 

 dered above and below with a line of greyish white ; upper tail-coverts bronzy green, with a crescentic 

 mark of blackish brown near the end, and tipped with grey; tail very dark green at the base for half its 

 length, and as far as this colour extends the shafts are white, except those of the two central feathers, which 

 are dark ; the remainder of the tail is brownish black, the lateral feathers narrowly edged with greyish white 

 on their inner webs near the end, and a broader mark of white on the edge of the outer webs, the projecting 

 ends of the central feathers gradually fading into white ; throat and breast ashy brown, intermixed with grey- 

 Ish white, presenting a rough shaggy appearance ; there is also a white line running down the centre of the 

 throat to the breast; abdomen greyish white; under tail-coverts ashy brown with grey margins; wings 

 purplish brown ; upper mandible and point of the lower mandible black, the basal portion of the latter 

 yellow ; irides black ; feet yellowish. 



The figures are of the size of life. The plant is the Jngidoa unijiora.
