GEOGRAPHICAL ZOOLOGY. 



[PART iv. 



(belonging to the genera Carpodectes and Cotwga] are found north 

 of Panama, and there are none in the West Indian islands. The 

 great majority of these, the true Chatterers, are from the regions 

 about the Equator. 



Sub-family VI. GYMNODERIN^E (7 genera, 14 species). Ranges 

 from Brazil to Costa Rica ; two species, of the genera Chasmor- 

 hynchus and Cepkcdopterus, are found north of Panama, while 

 there are none in the West Indian islands. Only 2 species are 

 found south of the Amazon valley.

 GENERAL DISTRIBUTION. 



The Phytotomidae, or Plant-cutters, are singular thick-billed 

 birds, strictly confined to the temperate regions of South America. 

 The single genus, Phytotoma, is found in Chili, La Plata, and 

 Bolivia. Their affinities are uncertain, but they are believed to 

 be allied to the series of families w^.th which they are here 

 associated. (Plate XVI. Vol. II. p. 128). 



FAMILY 43. EURYL^EMIDJE. (6 Genera, 9 Species.) 

 GENERAL DISTRIBUTION. 



The Eurylsemidae, or Broad-bills, form a very small family of 

 birds, often adorned with striking colours, and which have their

 are evidently the remains of a once extensive group, and from 

 the small number of specific forms remaining, seem to be on
