IOI4 VISCHFANGER— VOMER 



assigned another place to two of them, Hylophilus and Cydorhis, 

 so that the position of Vireosylvia, Vireo, Neochloe, Laletes and 

 Vireolanius only can be regarded as undisjjuted; and it is in the 

 first of these that the tenth (usually numljered the first) primary is 

 always small and frequently wanting/ the type species, commonly 

 called V. olivacea,^ being, it is said, variable in this respect (Ridgway, 

 Man. N. Am. B. p. 469, note). This bird, the Red-eyed Fly- 

 catcher of many writers, is a well-known summer -immigrant to 

 eastern North America which has even reached Greenland, and has 

 been recorded as accidentally occurring in England (E. Brown, in 

 Mosley's Nat. Hist. Tuthury, p. 385, pi. vi.). The type of Vireo, in 

 which the wing has 1 undoubted primaries, is the White-eyed Fly- 

 catcher of many writers, V. noveboracensis, also a native of North 

 America, but ha-\dng a more southerly range, and being abundant 

 all the year round in Bermuda. Of these two genera, 1 7 species or 

 races were recognized as found in the territory of the United States 

 by Prof. Coues in 1884, and 21 by Mr. Ridgway in 1887. All seem 

 to have much the same habits, among which must be mentioned the 

 utterance of loud and melodious notes,- in some cases sufiiciently 

 connected to form a real song, and the peculiar structure of their 

 nests, which are built in the fork of a horizontal branch, between 

 the prongs of which the beautifully- woven fabric is suspended, just 

 as among the Oriolidse, and it is to be remarked that the eggs are 

 very similar in coloration and markings to those of the true 

 Orioles. Of the rest, Neochloe, if that really belongs here, is 

 Mexican, and Laletes peculiar to Jamaica, each of them having but 

 a single species, while of Vireolanim there are foui- ranging from 

 Mexico southAvard to Ecuador {Cat. B. Br. Miis. viii. pp. 292-.316). 



VISCHFANGER (Fish-catcher), the Dutch name used in the 

 Cape Colony for Haliaetus vocifer (Layard, B. S. Afr. p. 17), an 

 Eagle (p. 176). • "^

VOLUCRES, Bonaparte's name in 1850 (Comp. Av. i. p. 57) 

 for the first of the two " Tribus " into which he divided the Order 

 Passeres, the second being Oscines, maldng the former to include 

 all the Picarise of this work as well as the Tracheophon^. 



VOMER, a median bone of the SKULL (p. 871), so called from 

 its general resemblance to a ploughshare in shape, though varying 

 much in that respect, as well as in comparative size and its con- 

 nexion Avith other bones, so as to be of considerable taxonomic 

 value. 



1 On this Baird's note (o;;. cU. p. 325) is impoytant, shewing a great advance 

 on the statements of other taxonomers. 



- Whether it should bear this name is questionable.
