This little Wren is very closely allied to T. aedon of the United 

 States, of which I have also specimens from Guatemala ; but it is 

 readily distinguishable by its clear, rufous under surface, more distinct 

 supercilia, and rather darker upper plumage. On disturbing the 

 feathers of the uropygium, a small white medial spot is seen in the 

 interior, as in T. aedon and several other species.

These specimens settle the locality of this bird, which was not 

 certainly known. I do not make the dimensions quite so large as 

 M. de Lafresnaye (these examples measuring, long, tota 6*9, alae 

 3*5, caudse 3*3), but I have little doubt the species is the same.

Rather larger in dimensions than a California!! specimen in my 

 collection, but apparently hardly distinct.

Of this rare and beautiful species the Bremen Museum (as I am 

 informed by Dr. Hartlaub) possesses specimens (as also of D. ni- 

 grescens) collected by Wahlberg near Sitka in Russian America in 

 57° N.L., Oaxaca being in 17° N. L. nearly ! This gives a distance 

 of no less than 40° of latitude to the range of the migration of this 

 species.

There can be no doubt, on comparison, that M. Giraud' s plate is 

 intended for the female of this species. Mr. Cassin informed me 

 that this was likely to be the case. All these three species of "Wood-
