is smaller in size, and has no bars on the wings (these being edged 

 outwardly like the back, only slightly more rufescent in tinge), and 

 is pale rufous below instead of white. It seems to be distinct from 

 any described species.

Four specimens of a species of Wren which I have hitherto re- 

 ferred to T. a'edon of N. America. The recurrence of examples in 

 the same plumage, differing from that of T. a'edon in being of a pale 

 rufous tinge below, inclines me to think that it is really a distinct 

 species.

Four examples of this Wren were procured at Playa Vicente in 

 May last. The sexes are similarly coloured. The bird belongs to 

 a smaller and weaker form of Cyphorinus, as distinguished by its 

 compressed lengthened and incurved bill, short tail, and long tarsi, 

 and is congeneric with the preceding species, though perhaps both 

 are strictly divisible from C. thoracicus and C. cantans.
