Fig. i. Range of Richmondena phccnicea, a characteristic species of the 

 Arid Tropical Zone of Venezuela, but which does not pass beyond the Goajira 

 region in Colombia. 



None of these forms are known to range beyond the aforesaid limits 

 in the present region : they are all strictly arid in their distribution, 

 entering our region from the east, and not going very far. (Compare 

 Figure I.) But there is another and larger class of species, just as 

 clearly Arid Tropical in their affinities, which have penetrated farther — 

 some of them much farther — to the west. These are as follows: 



Geranospisa cccrulescens 

 Pagolla wilsonia crassirostris 

 Lcptotila verreauxi verreauxi 

 Chamcepelia passerina albivitta 

 Scardafella squammata ridgzvayi 

 CrossophthaUnus gymnophthdmos 

 Brotogeris jugularis jugularis 

 Eupsittula pcrtinax ccruginosa 

 Otus cJioliba margaritcc
