149. Pulsatrix perspicillata perspicillata (Latham). 



Syrnium perspicillatum Bangs, Proc. Biol. Soc. Washington, XII, 1898, 132 

 ("Santa Marta "). — Allen, Bull. Am. Mus. Nat. Hist., XIII, 1900, 131 

 (Bonda ; plum.). 



Five specimens : Bonda and Dibulla. 



These agree in all respects with a topotypical example from Cayenne. 

 The species seems to belong to the littoral Tropical Zone, here as else- 

 where in Colombia. The Dibulla specimen was taken near sea-level, 

 in the heavy forest. 



150. Otus choliba subsp. 

 One specimen : Las Taguas. 



This individual is apparently referable to O. choliba, judging from 

 the buffy tinge of the under plumage, which is said to be characteristic 

 of this species, but it certainly differs from all of the rest of the 

 series in the collection of the Carnegie Museum. Mr. Waldron De 

 Witt Miller has kindly compared it with the material in the American 

 Museum of Natural History, and reports as follows : "' I have com- 

 pared the skin of Otus with all our specimens of the genus, and find 

 nothing very closely resembling it ; it differs from all our specimens 

 of O. choliba in the finer streaking of the underparts ; in this respect 

 it agrees much more closely with our single skin of O. ' fulvescens' 

 from Matto Grosso, but the general tone of coloration of your bird 

 is much less fulvescent." Coming as it does from a locality within 

 the Subtropical Zone, it may very well represent a distinct form, but 

 until more specimens have been collected it would be unwise to for- 

 mally characterize it. 



151. Otus choliba margaritae Cory. 

 Three specimens : Bonda. 



An adult female and two young birds, still in juvenal dress, but with 

 wings and tail fully grown, collected at Bonda May 1, 1899, together 

 with a specimen from Calamar, Colombia (near the mouth of the 

 Magdalena River) differ from a series of specimens from Costa Rica 

 and Panama in being paler, more buffy, less rufescent above, and also 

 in being slightly smaller. The adult from Bonda is paler below, with 

 the dark cross-barring less distinct than in the Calamar bird, but obvi- 

 ously belongs to the same form. They agree fairly well with two 

 other specimens from Margarita Island, but not with the type of
