NATURAL SCIENCES OF PHILADELPHIA. 287 



All of these species are in the Academy Museum, and of the first three nu- 

 merous specimens. Those three species are accurately and handsomely 

 figured by Dr. Sclater in his Monograph of the genus Calliste. 



2. Calliste Eannahi^:, nobis, (Plate 1, fig. 2.) 



Resembling generally C. cyaneicollis (D'Orbigny,) but is rather larger, has 

 the bill much smaller, and the abdomen always black (not blue as in that 

 species.) The blue of the head above is also different in shade, being paler 

 in the present bird, and this color has much greater depth, each feather being 

 black at base, and with its terminal half pale verditer blue. 



Entire head verditer blue, tinged with indigo blue on the throat ; back and 

 entire under parts lustrous black ; shoulders golden green ; greater coverts 

 yellowish green ; rump and upper tail coverts lustrous bluish and yellowish 

 green. Quills black, edged externally with bluish green ; tail black, all the 

 feathers narrowly edged with green ; under tail coverts black, with bluish 

 green edges ; under wing coverts black ; bill and feet black. A narrow frontal 

 band and stripe in front of the eye black. 



Total length about 5 inches ; wing 2| ; tail 2 inches. 



Hab. Merida Mountains, Venezuela. 



Of this bird, I have now two specimens, one of which was brought from the 

 locality above given, by Mr. George Robbins of this city, and which is un- 

 doubtedly correct. At first sight it much resembles C. cyaneicollis, but is 

 not difficult to distinguish by the abdomen being quite black, uniform with 

 the other under parts, and by the different blue color of the head, as above 

 mentioned. The small bill in the present bird is also a strong character. 



Numerous specimens of C. cyaneicollis are in the Philadelphia Academy, 

 two of which are types from M. D'Orbigny's collection. All of them, and all 

 others that I have seen, have the blue abdomen well marked as a character, 

 and in one evidently quite mature specimen, marked "Chili," this character 

 is so strongly developed and the blue color extends so far upwards towards 

 the breast, that it seems to have induced some attention, and the specimen 

 has been labelled in Europe " Esp. nouv. ?" In this specimen and others, 

 the blue of the head is quite superficial. One other specimen, from M. D'Oj- 

 bigny's collection, is in young plumage, but has the abdomen blue, though 

 that color is only incipient on the top of the head. All have the bill larger 

 than the present species. Our figure represents this bird of the size of life. 



To one possessing attributes amongst the most noble of Christian civiliza- 

 tion, an affectionate and most exemplary wife and mother, this bird is dedi- 

 cated !

 Of this curious bird no other specimens have come under my notice, than 

 those described as above, which were obtained in the Cordilleras Mountains in 

 New Grenada, by Mr. Charles J. Wood, of this city. It is given in our plate, 

 of the natural size.

 Since the publication of my description above cited, fine specimens of this 

 bird have been received from Panama by Mr. George N. Lawrence, of New 

 York, who notices them in his interesting and valuable papers on the birds 

 of that isthmus, in the Annals of the Lyceum of Natural History of that city. 

 The figure in our plate represents the adult male, and is about two-thirds of 

 the size of life. 



5. Monasa pallescens, Cassin, (Plate 4.)

 No other specimens of this bird have come under my notice since the pub- 



1864.]
