The relationship of this form to P. ruHlus (Vieillot) is certainly 

 very close, although it may be allowed to stand as a distinct species 

 for the present. It differs from rutilus in the dusky spotting of the 

 breast — a character which, however, varies greatly in different indi- 

 viduals, being scarcely apparent in No. 42,390, for instance, while in 

 No. 38,086 the markings of this part are so heavy as to appear as 

 streaks, and the middle of the abdomen is also distinctly spotted. In 

 Juvenal dress the spotting appears to be wanting, and it may become 

 more prominent with age. An occasional individual of rutilus has the 

 breast spotted, and it may very well be that the two forms intergrade. 



A resident of the foothills section of the Tropical Zone, but not 

 abundant anywhere in its range. It is partial to the low, tangled 

 woodland growth lying between the semi-arid coast belt and the heavy 

 forest of the higher altitudes, frequenting the undergrowth and masses 

 of fallen trees and vines which abound in such situations. As a rule 

 it is a silent bird, but occasionally it gives utterance to a rather pleas- 

 ing song.

The proper disposition of the Santa Marta Banded-bellied Wren, as 

 represented by a single specimen in the collection of the U. S. National 

 Museum purporting to come from that region, has been the subject of 

 considerable discussion in the past, to which the present writer, although 

 with more ample material before him than was available to his pre- 

 decessors, has more recently made an unenviable contribution. The 

 difficulty all along has been that Lafresnaye's type-specimen of fascia-
