488 HISTORY OF THE GENUS VIREO 



delpMca, and V. JlavoviridiSj the second of these being after- 

 ward made the subject of several special papers.* The following 

 year, Dr. S. W. Woodhouse described the remarkable V. atri- 

 capillus, and Cabanis shortly afterward (1855) separated the 

 Floridan harhatulus by name from the Antillean species, with 

 which it had before been confounded. John Xantus dedicated 

 a new species to Cassin in 1858 ; and in that year Baird gave 

 a new recension of the genus, which he divided into Yireo- 

 sylvia, Vireo, and Lanivireo, basing the last name on V. flavi- 

 frons; he also described the Western form of gilvus under the 

 varietal name swainsoni. A notable incident in the career of 

 Vireo was the appearance of one of its species in England, as 

 recorded in 1864.t In 1866, 1 increased the number of known 

 species by three, discovered in AT\zona—plumbens, vicinior, 

 and pusillus; and the same year appeard that portion of Baird's 

 " Eeview '• treating of the Vireonidce — for Selater had raised 

 Vireo and its allied genera to the rank of a family in 1862. In 

 this notable monograph, by far the most elaborate and satis- 

 factory we possess, Baird rearranged the subdivisions of Vireo, 

 and added a fourth subgenus, Vireonella, based ui^on the Cuban 

 V.gundlachi. He added nO North American species, but 

 described several new extralimital ones, which, with others 

 already and since described, form the complement of the genus 

 Vireo as now known to us. 



But the various attempts which have been made to sub- 

 divide the genus have met with only a succds d^estime — in 

 i'act, the species of Vireo seem scarcely susceptible of grouping 

 in subgenera without some violence, especially since we have
