Gkxeka, Saxicola, The Stonechats. 



Cyanecvla, The Blue-throat. 

 Sialia, The BIuel)irds (3 species). 



Sub-genera, There seems no good reason for any separation here into 

 sub-genera. As the first two o:enera are each for a single species, Siqlia 

 alone remains, and this seem incapable of any further division. 



Sub-family f REGULIN-ffi Kinglets 

 Bill very small and delicate, short, and straight ; nostrils 

 more or less exposed ; wings straight, with a spurious 

 first quill ; tail emarginate or almost even ; tarsus booted, and 

 longer than the middle toe and claw. Species very small. 



Genera, Phylloscopus, The Kennicott's Warbler. 

 Regulus, The Kinglets (o species). 



Sub-genera, None, as of the two genera the former is for a single species 

 and the latter is the same as its neighbor Sialia, incapable of further di- 

 vision. 



Sub-family / POLIOPTILIN^ G-nat-catchers 



Bill much as in the last sub-family {Regulhue) but longer 

 and very slender, wide and fiat at base, with notch and hook 

 at tip ; rictus with bristles ; nostrils not covered ; first quill 

 half as long as the second ; tarsus scutellate. 



Genhs, PoliojiUla, The Gnatcatchers (3 species). 



To transfer Phainopepla and Myiadedes (each for a single 

 species) to the Thrush family, as is done by some authors, (af- 

 ter Sialia and before Polioptila,) from the family of the Wax- 

 winr/s may, presently, become established, — it is not neces- 

 sary to discuss the change here. 



FAMILY II CHAMAEIDAE THE WREN TIT 



Latin caDia and (ireek rhumai, to dwell "on the ground." 

 A small family which it is very hard to define. While rad- 

 ically different from any of the Thrmhes, it has been placed 

 with the Wrens, though seemingly with more of a likeness to 

 the Titmice: Wings short and rounded, very noticeably so, 

 and about one-third siiorter than the tail, which is also round-
