D The Origin of the Avifauna of the Bahamas. 531 
3. Coccyzus minor maynardii—A resident representative of 
Coccyzus minor, a species of general distribution throughout the 
West Indies and coasts of the surrounding mainland. In South- 
ern Florida it occurs only as a summer resident, and is not there 
distinguishable from the Bahaman bird. 
4. Saurothera bahamensis—Known only from Andros and 
New Providence. Allied species of this very distinct West 
Indian genus occur in Cuba, Jamaica, Hayti, and Porto Rica. 
The Bahaman species most closely resembles Saurothera vieilloti 
of Porto Rica. When we consider the limited power of flight 
now possessed by this species (Dr. Northrop states that he was 
told they could be captured after a short chase),‘ its appearance 
in the Bahamas is certainly remarkable. Nor can we here argue 
loss of flight-power through the influences of an insular exis- 
tence, for the bird’s congeners are no better adapted fcr extended 
journeys. 
5. Dryobates villosus maynardii—A common resident of An- 
dros, New Providence, and Abaco. It differs very slightly from 
the Florida form, Dryodates villosus audubonit. 
6. Centurus nylanus. 
7. Centurus blaket_—This is one of five instances in which a 
Bahaman form has become further separated into two or more 
forms inhabiting different islands. Centurus nylanus is found on 
Wattling’s Island, while C. d/akei is known only from Abaco. 
They are closely related to each other, and also to their obvious 
_ ancestor the Cuban Centurus superciliaris. 
8. Doricha lyrura. 
9. Doricha evelyne—The first of these nearly related species is 
apparently restricted to Inaugua and Long Islands; the second 
-~ has a wider range, and has been found on most of the remaining 
islands. The genus Doricha is Central American, and not else- 
where represented in the West Indies. The presence of these 
two species in the Bahamas is, therefore, not easily accounted for. 
Doricha elize,the most northern species on the mainland, is found 
in the vicinity of Jalapa. The Bahaman birds, however, more 
closely resemble D. dryanti of Costa Rica.
