397. Vireosylva flavoviridis flavoviridis Cassin. 



Vireo flavoviridis Allen, Bull. Am. Mus. Nat. Hist., XIII, 1900, 173 (Bonda). 

 Vireosylva flavoviridis flavoviridis Ridgway, Bull. U. S. Nat. Mus., No. 50, 

 III, 1904, 144 (Santa Marta region; crit.). 



Seventeen specimens : Bonda, Buritaca, Mamatoco, Gaira, Punto 

 Caiman, Tucurinca, and Fundacion. 



This species is fairly common throughout the lowlands, not going 

 above 1,000 feet, and being especially numerous in the section from 

 Santa Marta to Fundacion. There is no evidence, however, that it 

 breeds anywhere in this region. Mr. Smith's specimens were all shot 

 between August 12 and October 13, while the dates for those above 

 listed are also in the same months, up to October 20. Mr. Cherrie 

 {Auk, VII, 1900, 329-331), writing of its habits as observed in the 

 vicinity of San Jose, Costa Rica, says that it is only a summer resident 

 there, disappearing at the beginning of the dry season (September), 

 and not reappearing until April. Unfortunately very few of the South 

 American records for this species have exact dates attached, but Salvin 

 and Godman (Biologia C entrali- Americana, Aves, I, 1881, 189) inti- 

 mate that the individuals observed in the far south may have been 

 there for the winter only. At any rate, all the available information 

 goes to show that V. flavoviridis is as strictly migratory as certain of 

 its northern congeners, and it seems best to regard it as a winter resi- 

 dent, or perhaps only a transient visitant, in the Santa Marta region. 



398. Vireosylva calidris calidris (Linnaeus). 



Vireo calidris calidris Allen, Bull. Am. Mus. Nat. Hist., XXI, 1905, 277 

 (Bonda and Masinga [Vieja] ; crit.). 



Dr. Allen records two specimens referable to this form, one from 

 Bonda, August 19, and the other from Masinga Vieja, September 7. 

 The writer has examined the specimens in question, and fully agrees 

 with this determination. It is presumably a winter resident in the 

 Santa Marta region, although both the records lie in the season of 

 migration. 



399. Vireosylva calidris barbatula (Cabanis). 



Vireo calidris barbatula Allen, Bull. Am. Mus. Nat. Hist., XIII, 1900, 173 

 (Bonda); XXI, 1905, 277 (Bonda; crit.). 



Three specimens : Mamatoco and Tucurinca. 



After careful comparison we refer these three specimens to V. c.
