supposed species to the rank of geographical races or subspecies may he 

 further carried is not vet known, but the material examined by Mr. Al- 

 len foreshadows still further reduction. For example, "the Cayenne form 

 known as C. guianensis," says Mr. Allen, "probably will be found to 

 grade into C. viridis through a paler race representing the species in 

 northeastern Brazil, . . . for which Baird's name ccarensis {—albiventris) 

 would be available. In short, it seems probable that the whole group 

 centring about C. Jiavipectus, including not only its several recognized 

 subspecies but C. guianensis and C. viridis, and possibly also C. flaviven- 

 tris through its southern forms,* will be found, when ample material for 

 the study of the genus has been gathered, to imperceptibly blend." 



The article is supplemented by Mr. Allen's "present impressions of the 

 status, relationships, and distribution of the various forms of Cyclorkis" 

 concluding with an excellent key to the species. — R. R. 



Allen's Descriptions of New South American Birds. — Eight new 

 species and subspecies, belonging to various families, are described in this 

 paper, f as follows : (i) Thryothorus macrurus, Bogota; {-)7\ longipes, 

 Ambato. Ecuador; (3) Platy rhynch us bifasciatus, Chapada, Matto Grosso, 

 Brazil; (4) P. insular is, Tobago ; (5) Euscarthmus ochropterns, Chapada, 

 Matto Grosso; (6) Sublegatns virescens, Chapada; (7) Empidonax lazv- 

 rencei ( = Oct//<vca flaviventris Lawr.) ; (S) Thamiiopthilus doliatus mcxica- 

 nus (=7- affinis, Cab. & Heine, pre-occupied). The "remarks" on other 

 species refer to the following: (1) Thryotkorus " mysticalis" of the Rusby 

 Collection, which proves to be "probably a large, very strongly colored 

 example of T. genibarbis, or else an undescribed form" somewhat inter- 

 mediate between the latter and T. mysticalis; (2) Porphyrosfiza c&rules- 

 cens (Max.), this being the correct name for the bird usually called P. 

 cyanella (Sparrm.); (3) Mccocercnliis uropygialis Lawr., a specimen of 

 which, "said to have been collected at a point thirty miles north of Bo- 

 gota" is in the collection of the American Museum of Natural History, 

 "thus greatly extending the range of the species to the northward"; (4) 

 Euscarthmus pelzclni Scl., a second specimen of which is in the collection, 

 from Cuyaba, Matto Grosso; (5) Habrura superciliaris (Wied), being the 

 species usually called H. pectoralis (Cab. & Heine) ; (6) Habrura minima 

 (Gould), very generally synonymized with H. pectoralis, but restored 

 to specific rank J; (7) Phyllomyias incanescens (Wied), which is now first 

 referred to its proper genus, being the Muscipe/a incanescens of Wied. ot 

 which Pkyllomyias berlepscki Scl. is a synonym; (S) Ornithion cineras- 

 ccns (Wied), being the bird usually called O. obsoletum {Muscicapa obsolcta 



* Unfortunately we are not informed what these "southern forms" of C.fiaviventris 

 are!

 species is shown to be the type, instead of H. pectoralis, as given by Sclater.
