490 Mr, P. R. Lowe — Observations 



Coerebidge) is in point of distribution entirely confined to 

 the Neotropical Region (see Map^ PI. VII.). Its range 

 in this region is fairly comprehensive, being comprised, 

 as regards the continent, within the vast extent of forest- 

 clad land which lies between the latitudes of 20° N. and 

 (roughly) 30° S., and embracing (with a few exceptions to be 

 presently mentioned) the whole of the West Indian Islands. 



In tlie Bahamas the genus attains its furthest northern 

 limits (lat. 27° N.), an extension rendered possible by the 

 warm waters of the Gulf Stream, which bathe these low- 

 lying coral-islands. A small colony has also been reported 

 from Indian Key on the west coast of Southern Florida, 

 which may have been derived from wind-blown stragglers 

 from the Bahamas. 



Excluding these last, the present existence of which is 

 possibly doubtful, I have been unable to discover any records 

 of the occurrence of the genus on the continent further 

 north than Jalapa and Vera Cruz on the eastern shores of 

 Southern Mexico (lat. 20° N.). 



From these latitudes the northern limits of the genus are 

 represented by a line which skirts the northern boundaries 

 of Guatemala and then pssses eastwards to Jamaica in a 

 curve which includes the islands of Cozumel and the 

 Caymans. From Jamaica the line is again continued east- 

 wards and northwards through the Windward passage so as 

 to include the Bahama Group. 



Neither Yucatan, nor British Honduras, nor Cuba are in- 

 cluded within the limits of the northern range of the genus. 

 Whether Honduras proper is likewise outside these limits 

 I have been unable to ascertain; but ahhough there are 

 no available records of the occurrence of the genus in that 

 country, it would be altogether surprising to find no species 

 of it represented in at least its more western parts. 



The southern limits of the genus, so far as present records 

 go, are represented by a line which passes along the southern 

 borders of Peru and Bolivia and then southwards and east- 

 wards to strike the eastern coast of South America to the 

 south of the province of Rio Grande do Sul in Brazil.
