4. Note on the Zoological Appendix to the ' Report of 

 THE U.S. Naval Astronomical Expedition to the 



SotTTHERN HeMISPHERE,' AND ON THE GeOGRAPHIC 



Range and Distribution of the Tanagrine Genera 

 Calliste and Euphonia. 



By Philip Lutley Sclater, M. A., F. Z. S. 



The second volume of the ' Report of the U.S. Navai Astronomi- 

 cal Expedition to the Southern Hemisphere,' of which copies haye 

 lately been received iu this country, contains a very valuable account 

 of the specimens of natūrai history coUected by the Expedition in 

 Chili. Each section of the Zoology appears to have been assigned 

 to the person best qualified to undertake it. The Ornithological 

 part (by Mr. Cassin) is illustrated by some very nicely colonred 

 platės, and contains a list of the Birds of Chili, with many interest- 

 ing notes on their native names, habits, &c. 



Wliat I particularly wished to notice, however, was, that there 

 are three species of Tanagers — Callistce cijaneicollis and yyroloides 

 and Euphonia rufiventris — included in this list, and apparently in- 

 tended to be represented as inhabitants of the republic of Chili. 

 Now I have always supposed, and still believe it to be the case, that 

 these genera of Tanagers do not extend on the western side of the 

 Andean range nearly so far south as that country. Indeed Tschudi 

 and D'Orbigny assert that they are only found in the wood regions 

 of Peru and Bolivia on the eastern slope of the Andes, and I have 

 never seen examples of birds belonging to either of these genera in 

 Chilian collections ; nor are they, or other similar tropical forms, 

 mentioned as occurring there by the several previous writers on the 

 zoology of that country. Under these circumstances I cannot help 

 thinking there mušt have been some error with regard to the locality 

 of the specimens of these Tanagers proeured by Lieut. Gillis's expe- 

 dition. 



I may remark at the šame time that the bird figured in this šame 

 work, pi. iviii. fig. 2, as a companion to Calliste cyaneicollis, is not 

 Calliste larvata (Du Bus), but Calliste thalassina, Strickland {Aglaia 

 fVilsoni, Lafr. — Des Murs, Icon. Orn. pi. 56. fig. 2). 



The appended Table shows the distribution of the species of the 

 genus Calliste as far as I have been able to collect Information on 

 the subject. It will be observed, that only one of this genus has 

 yet been found north of the isthmus of Panama, though very possibly 

 new species are yet to be discovered in the unexplored parts of 

 Central America. The metropoUs of this group seems to be the 

 wood regions of New Grenada, Ecuador, Peru and Bohvia ; but we 

 require much more Information concerning the local faunse of tliis 

 great continent before very accurate statistics can be drawn up of the 

 geographical distribution of these and other forms of animal hfe.
