•70 Bangs, Birds of San Miguel Island. fjan' 



Elaenia placens Scl. — One adult male, taken May 5. 



Sublegatus arenarum {Salvin). — Five specimens, four males, one 

 female, April and May. 



These skins are inseparable from southern examples, that have been 

 called 5". glaber Scl. & Salv., and substantiate the opinion of Messrs. 

 Salvin and Godman (Biol. Cent. Am., Vol. II, p. 37), that the species 

 must be known as 5. arenarum. The type locality of .S". arenarum 

 (described as Elainea arenarutn) is Punta Arenas, Costa Rica. 



Myiobius naevius (Bodd.). — One adult male, May 7. 



Myiarchus panamensis La-wr. — Twelve adults, both sexes, April and 

 May. 



In the San 'Miguel Island series the wings seem to average a trifle 

 shorter and the back is ver\- slightly darker in color, than in a series 

 from Loma del Leon, Panama, but these differences are not enough to 

 warrant separating the island bird by name. 



Tyrannus tyrannus {Linn.). — One female, taken April 27,3 migrant. 

 This is a small billed example, and therefore a bird that would breed far 

 north. 



Tyrannus melancholicus satrapa {Lic/if.). — Ten adults, both sexes, 

 April and May. 



Cercomacra maculicaudis {Sc/.). — Eleven adults, both sexes, April and 

 May. 



Drymophila intermedia {Cab.). — Two adult males, April 30 and May i. 

 These agree exactlj' with southern specimens (Venezuela and Colombia). 

 San Miguel Island, however, appears to be the most northern record for 

 the species. 



Thamnophilus doliatus nigricristatus {La-wr.). — Six adults, two males 

 and four females, April and May. The two males are extreme examples 

 of the black-capped form — nigricristatus. 



Vireo chivi agilis {Licht.). — Four specimens, two pairs, all taken April 

 29. This was an uncommon bird on the island, and in one place Mr. 

 Brown found these two pairs. He thinks he saw no others during his 

 stay. 



The color of the back is rather darker than usual, but the birds are in 

 worn plumage and in all other respects agi-ee with mainland specimens 

 of agilis. 



Thryophilus galbraithi Lawy. — Eight adults, both sexes, April and 

 May. 



These examples are almost iinperceptibly more reddish on the back than 

 mainland birds. 



Seiurus noveboracensis {Gmel.). — One female, taken April jq, a 

 migrant. 



Dendroica vieillotii Cassin. — One male, taken May 7. in rather worn 

 plumage. 



Coereba mexicana Columbiana {Cab.). — Fourteen specimens, adults of 

 both sexes and three nearly full grown young, just emerging from nestling 

 plumage, taken April 20, May 4, and May 5.
