308 PROCEEDINGS OF THE ACADEMY OF [1899. 



Piranga rubra (L.)- 



Honda, March 21, 1889. 



Conirostrum rufum Lafr. 

 Heleodytes nuchalis (Cab.). 



Two specimens, without locality, have the sandy tint on the nape, 

 and thus differ from H. pardus Scl., the Colombian form, indi- 

 cating that the latter may be, as suggested (Brit. Mus. Cat., vi, p. 

 204) only an individual variation of nuchalis.^ 



Troglodytes striatulus Lafr. 



Honda, two specimens. 

 Troglodytes columbse sp. nov. 



Type 35,354, Coll. Acad. Nat. Sci. Vicinity of Bogota. 



It is with some hesitation that I add another to the long hst of 

 names proposed for South American Wrens, but this is so different 

 from any described form that there seems no alternative. 



This bird is nearest to T. striatulus, but is darker and more olive 

 brown above, without a trace of the rufous tints so characteristic 

 of South American species of Troglodytes. T. striatulus is practi- 

 cally without rufous tints, but the feathers of the rump or upper 

 tail coverts as well as the tail are lighter and incline to rufous or 

 yellowish brown. There is no trace of this, however, in T. colum- 

 hoi, both rump and tail being dark olive brown. The black bands 

 on the tail are rather more irregular than in striatulus and those on 

 the back are a little more pronounced. The under surface is quite as 

 different from T. striatulus as are the upper parts; it is uniform 

 ochraceous or vinaceous from the chin to the vent without a trace 

 of white, and no trace of fulvous on the flanks which are uniforna 

 in ground color with the rest of the lower surface. The sides and 

 flanks are shaded with olive brown and obscurely banded. The 

 under tail coverts are buffy, with a slight rufous tinge, and are 

 strongly barred with black. The bars do not quite reach the edges 

 of the feathers, and are connected down the shaft. The sides of 

 the head are almost exactly like T. striatulus, but with the ground 

 color darker. Length of wing, 2.15 ins. 



This is the darkest Troglodytes that I have seen from South or 



^ It is possible this, as well as some others of the unlabelled specimens, 

 came from Cartagena. See pp. 312-13.
