426 SYNONYMY OF PETROCHELIDON LUNIFRONS 



in the different genus Hylochelidon Gould. Several species of 

 true Petrochelidon occur in Central and South America and the 

 West Indies, the actual number being in question. Pending 

 satisfactory answer, I continue to present our Cliff or Eave 

 Swallow, lunifrons of Say, as distinct from the West Indian 

 fulva of Vieillot, though not quite satisfied of specific distinc- 

 tion in this case 5 but I have little hesitation in assigning the 

 Mexican P. swainsoni Scl. (= melanogaster Sw.) as a synonym. 

 P.pceciloma of Jamaica and P. ruficollaris of Peru are closely 

 related.
