GEOGRAPHICAL ZOOLOGY. 



[PART IV. 



The Vireonidse, or Greenlets, are a family of small fly-catching 

 birds wholly restricted to the American continent, where they 

 range from Paraguay to Canada. They are allied to the Mniotil- 

 tida? and perhaps also to the Australian Pachycephalidse. Only 

 two of the genera, with about a dozen species, inhabit the 

 Nearctic region. The distribution of the genera is as follows : — 



Vireosylvia (13 sp.), Venezuela to Mexico, the Antilles, the 

 Eastern States and Canada ; Vireo (14 sp.), Central America and 

 the Antilles to Canada ; Neochloe (1 sp.), Mexico ; Hylophilus 

 (20 sp.), Brazil to Mexico ; Laletes (1 sp.), Jamaica ; Vireolanius 

 (5 sp.), Amazonia to Mexico ; Cychlorhis (9 sp.), Paraguay to 

 Mexico. 



Family 29— AMPELID.E. (4 Genera, 9 Species.) 



The Ampelidse, represented in Europe by the waxwing, are a 

 small family, characteristic of the Nearctic and Palaearctic re- 

 gions, but extending southward to Costa Rica and the West 

 Indian islands. The genera are distributed as follows : — 



( 1539 ) Ampclis (3 sp.), the Palsearctic and Nearctic regions, and 

 southward to Guatemala ; ( 1360 ) Ptilogonys (2 sp.), Central 

 America ; ( 1442 ) Dulus (2 sp.), West Indian Islands ; ( 1361 ) Phamo- 

 pcpla (1 sp.), Mexico and the Gila Valley. 



Family 30.— HIRUNDINID^E. ( 9 Genera, 91 Species.)
