At first sight this species bears a strong resemblance in coloration to Thryothorus 

 maculipectus, but differs in many respects, in having barred wings and in the distinct 

 character of the markings of the chest. At one time ^ we considered these two species 

 to belong to the same group of Wrens ; but a closer examination shows that, while 

 T. thoracicus has the open nostril of Thryophilus, T. maculipectus has the nostril with 

 overlying membrane, as in true Thryothorus. 



Through Mr. Lawrence's kindness we have had an opportunity of examining 

 his type of Thryothorus brunneus^, and found that it is undoubtedly an immature 

 example of the present species. We have figured this type ; and the plate will, we think, 

 show the correctness of our views respecting it. Thryophilus thoracicus seems to be by 

 no means a common species, as but few specimens have come under our notice. Our own 

 types, one of which we now figure, were obtained by Arce. near Tucurriqui in Costa Eica.

For several years this species was only known to us from the single specimen in Mr. 

 Sclater's collections, which once formed part of one of the large series of bird-skins
