Brunneus, pileo saturatiore, fere nigricante, alis caudaque nigro transradials : subtus saturate rufus, abdomine

 Sab. in republica iEquatoriali, regione littorali. 



Mr. L. Fraser, during his expedition to Ecuador, passed the three final months of the year 

 1859 at Esmeraldas on the sea-coast— the capital of the most northern province of the republic. 

 About 94 species of birds were obtained here, but although the locality had not, as far as we 

 know, been previously visited by collectors, very few of them proved to be new to science. 

 Amongst them, however, were examples of the present species of Wren, which was shortly 

 afterwards characterized by Mr. Sclater, from Mr. Fraser s specimens: from these also our figure 

 has been taken. Mr. Fraser states that the two examples obtained were met with " flying from 

 bush to bush, singing, along with four or five others." 



The present species is distinguishable from G. modulator by its blackish head and larger 

 bill, and from C. lawrencn of Panama by its brown belly, which is like that of C. modulator. 



The genus CyphorMnus of Cabanis, as restricted by Prof. Baird,* forms a small but well- 

 marked section of the family Troglodytidae, which is so largely represented in South America, 

 The characters which readily distinguish it from other sections of the family are the high straight 

 culmen, and more especially the circular nostril which is entirely surrounded by membrane. 

 We are acquainted with four species of the genus, which may stand as follows:—
