 ba^al joint of middle claw adherent for two-thirdfl ita length to basal Joint 

 of outer, and for same distance to aboat half basal joint of inner ; the adhenioii 

 less than in Vireo. 



In the preceding description I hnve combined the cliaractiTs of 

 the genus and the subfttrnily, as Dulus is tlius far the only known 

 member of the Dulinm. The form is a very peculiar one, and its 

 precise systematic position is a matter of much uncertainty. It lins 

 been placed by Dr. Sclater among the Vireonidse; but from tln'ni 

 it differs in the longer basal phalanx of middle toe ; less amount of 

 adhesion of the anterior toes ; shorter tarsi ; much Ijroader and 

 more deeply cleft gape ; less extension forward, more backwiird 

 direction, and softer texture of frontal feathers (the tips of which do 

 not run into bristles) ; fewer bristles about the mouth ; the broader 

 and more exposed nostrils, etc. The tip of outer claw reaches only to 

 base of middle claw, instead of nearly to the middle as in Vireonidse. 

 The genus was assigned by II. E. Strickland to the Ampelidfe, and 

 the. majority of its characters seem to indicate a place intermediate 

 in some respects between Ampelis and Ptilogonya, and I there leave 

 it for the present The longitudinal streaks of the under parts, 

 although more conspicuous, are somewhpt like those of the yonng

 None of the true Vireonidse, either as adults or young, as fur as 

 known, are at all streaked or spotted.
