THE HONEY CREEPERS. 



Small slender-, acute-, or hook-billed " uine-primaried " acutiplantar 

 Oscines with the tongue deeply incised (bifid or triiid) and fringed or 

 brushy at tip; transpalatine processes much reduced, forming minute 

 spikes or points; interpalatine spur abortive, or small; palatines pro- 

 duced backward over pterygoids. - 



Bill very variable in shape and relative length; sometimes rather 

 stout and bent wedge-shaped (i. e., the culmen decidedly convex, but 

 gonys straight); sometimes slender, slightly decurved terminally, and 

 as long as or longer than head {Cliloropliaiit'ti; Cyanerpes); sometimes 

 very acute at tip and more or less decurved {Cuerelxi; Daarvis), or much 

 compressed, with tip conspicuously hooked and angle of gonys pos- 

 terior to nostrils {Dlglossa; Dlglossopis). Nostril exposed, longitudi- 

 nal (linear or oval) overhung by membrane. Rictal bristles obvious 

 {C/ilorqpka7i^s, Dig^anna^ Glosslptila) or obsolete (other genera). 

 Wing moderate, rather pointed (eighth to sixth primaries longest, 

 ninth shorter than seventh but longer than fourth). Tail much shorter 

 than wing (usually shorter than distance from bend of wing to tip of 

 secondaries), even, emarginate, slightly double-rounded, or rounded. 

 Tarsus variable in relative length, distinctly scutellate anteriorly; 

 middle toe with claw about equal in length to tarsus (sometimes a little 

 more or less) ; basal phalanx of middle toe united for most of its length 

 to lateral toes, especially to the outer; claws of lateral toes reaching 

 about to base of middle claw; hallux about equal in length to lateral 

 toes but much stouter, its claw shorter than the digit. 



•'The CoerebidEe are all of small size; they have typical Oscinine 



' Hedescribed through inadvertence.
