specimen, but Provost's Tanagra ruficcni-x, the latter must also be the 

 type of I>esson's genus Iridosornis! Poecilornis Hartlaub. 1H44, 

 would be untenable for exactly the same reason, and we should have 

 to use Euthraiipis Cabanis, ISoO. 



According to our views the three subspecies are: — 



Iridosornh rufifcricx rufivertex (Lafresnaye). 



IridosorniJ^ rufivertex ignlcapillus Chapman.^ 



IridosoriiLi rufiocrtex caeraU'oceniris Chapman.- 



Tachyphonus surinamus brevipes Lafresnaye.

Tachyphonus Jiapcn^is La^^Tence, Ann. Lye. nat. hist. N. Y., 1864,

Berlepsch, Rev. tanag. (Int. ornith. kongress, 1910, p. 1, 148), 

 listed Tachyphonus brevipes Lafresnaye among undetermined species, 

 suggesting that it might be the female of Tachyphonus surinamus 

 (Linne). 



The two cotypes of T. brevipes Lafr. are adult females. They are 

 alike, each sho^nng to a marked degree the ochraceous buff throat 

 and breast characteristic of the female of the form we have been 

 calling T. surinamus napensis Lawrence. The female of T. suri- 

 namus surinamus (Linne) has the throat and breast cream buff. 

 Lafresnaye's specimens came from Colombia and the name Tachy- 

 phonus surinamus brevipes Lafr. must therefore replace Tachyphonus 

 surinamus napensis Lawr.
