326 REVIEW OP AMERICAN BIRDS. [PART I. 



Lanivireo. Body stout ; head broad. Bill short and stout, broad 

 at base, the culmeii curved from the base, the commissure con- 

 siderably arched. Bill blue black. Feet stout. Type V. /lavifrons. 

 Species V. Jlavifrons, solitarius, propinquus, plumbeus. 



ViREO. Wings short and rounded, a little longer than the tail, equal to it, or 

 shorter. First primary distinct and large, from two-fifths to half or more 

 the length of the second, shorter or not longer than the eighth. 



Vireo. Wings pointed ; first quill less than half the second, which 

 is about equal to seventh or eighth, and decidedly longer than the 

 tenth primary and the secondaries. Type V. noveboracensis. The 

 species coming under this section are noveboracensis, carmioli, atri- 

 capillus, huttoni, belli, vicinior,* and pusilla, 



Vireonella. Wings rounded, scarcely longer than the tail ; the first 

 quill half as long as the second (or more than half), which is not 

 longer than the tenth primary and secondaries, or even less. Bill 

 and feet generally much stouter than the preceding. Type V. 

 gundlachi. The species belonging here are modestiis,^ latimeri, 

 pallens, ochracvus, crassirostris, gundlachi, and hijpoc/irijseus. 



The Yireones are found throughout the New World, both to 

 the extreme north and south, each section having peculiar forms. 

 None of the North American species are ever met with in the West 

 Indies, excepting V. olivaceus, solitarius, Jlavifrons, and novebora- 

 censis, in Cuba, wliere they are extremely rare, and occur only as 

 stragglers. They, however, penetrate on the Continent far to the 

 south, in winter, some even reaching Bogota. 



VIREO SYLVIA, Bon. 



Vireosylvia,'Bo^. Geog. Comp. List, 1838. (^Type Muscicapa olivacea,Liy.) 

 Phyllomanes, Cab. Arch. Nat. 1847, 1, 321. (No type mentioned ; name 

 proposed as substitute for Vireogylvia.) 



Wings pointed, longer than the tail, which is nearly even, or very slightly 

 rounded. First primary (as in the type), wanting apparently in some species. 

 Bill elongated, about as broad as deep at base, then becoming more and more 

 compressed ; the commissure and culmen nearly straight to the abruptly de- 

 curved and hooked tip. Both mandibles with distinct notch, the lower also 

 slightly hooked. Nostrils open, oval, in lower edge of cavity, with membrane 

 above and behind ; the frontal feathers advanced and reaching nearly to 

 posterior edge. Bristles in frontal feathers and in rictus to moderate extent. 

 Legs in type rather short and weak ; tarsus but little longer than middle toe 



' V. vicinior has the first quill half or rather more than half the second, 

 but otherwise falls within the limits of the prer^ent section. 



2 V. modestus in very small bill and other characters belongs very near V. 

 hnttoni of the preceding section, although its short wing brings it under the 

 present one.
