Onychorhynchus mexicanus fratercuhis Bangs. 



Microcerculus corrasus - 



sp. nov. 



Microcerculus marginatus (Scl.), Allen, Bull. Amer. Mus. Nat. Hist., Vol. 

 Xni, p. 180. — (One specimen from Onaca provisionally referred to this species 

 by Allen.) 



Type, from Chirua, Sierra Nevada de Santa Marta, Colombia, 7000 feet 

 altitude, $ adult, no. 6070, coll. of E. A. and O. Bangs, collected March 13, 

 1899, by W. W. Brown, Jr. 



When I recorded, as M. marginatus, the only specimen taken by 

 Mr. Brown, it was done because I did not like to give the bird a 

 name then without having seen a skin of true M. marginatus, not 

 that I thought the Santa Marta scrub wren was really that species. 

 Since then I have examined all the material I could and have 

 studied plates and descriptions with great care, and I hesitate no 

 longer in naming the Santa Marta form. 



1 The culmen is measured from the base of the mandible, where it joins the skull, to the tip, as 

 the ' exposed culmen ' varies too much. 



2 Corrasus — procured with difficulty.
