This new species is allied to G. pumilum, and has been 

 identified with that species by Mr. Ridgway and others, but 

 it difiers in several characters : the tail-bands are five or six, 

 the head at all ages greyish, contrasting forcibly with the back, 

 and the rufous collar is often obsolete or absent; the tail, 

 instead of having large round spots, has white markings of 

 small size and rather inclining to bars ; the whole tone of the 

 plumage is more umber and not so rufous as the Brazilian 

 bird ; and this is especially true of the under surface, where 

 the sides of the breast are conspicuously spotted with white. 



This bird represents G. pumilum and G. gnoma in Central 

 America, and is intermediate between the two species ; but 

 there can be no doubt that it is specifically distinct from both. 



Glaucidium nanum. 



Characters of the species. — Female of decidedly larger bulk 

 than the male, and rather browner. Back everywhere mot-
