MNIOTILTHXE THE AMERICAN WARBLERS. 133 



slightly concave. Tongue lengthened, narrow, deeply bifid (for one third), and deeply 

 lacerated or fringed externally at the end; the edge along the median portion folded 

 over on the upper surface, but not adherent." (Hist. N. Am. B.) 



The curvature of the bill in Perissoglossa tigrina is quite peculiar 

 among the Mniotiltidce with notched bills, with the single exception 

 of Helminthophila bachmani. 



It seems likely that the Helinaia carbonata of Audubon belongs 

 here, as it appears very closely allied to the type of this subgenus. 

 The two species differ, however, as follows: 



COMMON CHAEACTEES. Male. Top of head black. Above olive, becoming yellowish on 

 rump. Head, neck, and lower parts bright yellow, becoming whitish posteriorly. Dorsal 

 feathers with black centres; breast and sides streaked with black. A black streak through 

 the eye. 



P. tigrina. Large white patches on inner webs of tail leathers. 



Sides of head and middle of throat tinged with chestnut. One large white patch 

 on wing, covering both rows of coverts. Outer web of lateral tail-feather blackish. 

 P. carbonata. No white patches on tail feathers. 



No chestnut about head. Two bands on the wing, the anterior one white, the 

 posterior yellow. Outer web of lateral tail-feather whitish.

HAB. Eastern North America, north to Hudson's Bay and Lake Winnipeg; breeding

 Jamaica. 



"Sp. CHAB. Bill very acute, conical and decidedly curved. Bill and feet black. Upper 

 part of head dull black, some of the feathers faintly margined with light yellowish brown. 

 Collar scarcely meeting behind, rump and under parts generally rich yellow. Throat, fore- 

 part of breast, and sides streaked with black. Abdomen and lower tail-coverts pale yel- 

 low, brighter about the vent. Ear-coverts light reddish-chestnut. Back part of a yellow 

 line from nostrils over the eye of this same color: chin and throat tinged also with it. A 

 black line from commissure through the eye, and running into the chestnut of the ear- 

 coverts. Back, shoulders, edges of the wing and tail, yellowish olive; the former spotted 

 with dusky. One row of small coverts, and outer bases of the secondary coverts, form a 

 large patch of white, tinged with pale yellow. Tertials rather broadly edged with brown- 

 ish white. Quills and tail dark brown, the three outer feathers of the latter largely marked 

 with white on the inner web; edge of the outer web of the outer feathers white, more per- 

 ceptible towards the base. Length, 5.25; wing. 2.84; tail. 2.15.
