APPENDIX. 495 



Family, CORVID^. 



40. Genus, DYSORNITHIA*. 



Rostrum brevissimum, conicum, basi latum, Bill very short, conic, the base wide, the 



lateribus compressis ; apice leviter arcuatd, sides compressed, the tip slightly bent and 



emarginatd. Vibrissas mastacales medium notched. Gonys ascending. Rictus with stiff 



rostri attingentes. Nares plumis recumbenti- bristles, half the length of the bill. Nostrils 



bus occultcB. Cauda mediocris, gradata. Tarsi concealed by incumbent feathers. Tail mo- 



medioc res ; digitus internusbrevissimus. Un- derate, graduated. Tarsi moderate. Inner 



guis posticus parum curvatus. Plumae dorsi toe shortest. Claw of the hinder toe but 



longissimoe mollesque. slightly curved. Feathers of the back very 



long and soft. 



Types. — Garrulus Canadensis, brachyrhynchus, infaustus. 



Obs — On attentively considering the sub-family Garrulinae, with reference to the acute observations of j Prince 

 Charles Bonaparte, I am led to believe that these birds constitute the scansorial type, representing the Pariance or 

 Scansorial Warblers. The short, broad bill, and the slender slightly curved toe, are thus explained, as also the unusual 

 familiarity of its manners. The union of this group with the Crypsirince is effected by an undescribed Australian 

 bird, sent to our museum by that acute botanist, Allen Cunningham, Esq. 



41. Genus, CYANURUS. 



Rostrum mediocre corv i; culmine plus quam Bill moderate, crow-like; the culmenmore 



gonyde arcuato ; apice fere integerrimd ; curved than the gonys ; the tip nearly entire ; 



tomiis curvatis. Pedes magni, validissimi ; the commissure curved. Feet large, very 



digiti laterales fere eequales. strong ; lateral toes nearly equal. 



Examples. — 1. C.cristatus. 2. Stelleri. 3. sordidus, Sw. 4. Floridanus, Bon. 5. coronatus, Sw.Syn. 6. cyanopogon 

 {PL col. 169). 7. piteatus {III. 58). 8. azureus {III. 168). 9. formosus {Pica formosa, Sw. Syn.) 10. cnstatellus 

 (PI. col. 193), &c. 



Obs. — This group is distinguished from the European and North Asiatic Jays by the upper mandible not being 

 abruptly bent at the tip, or very distinctly notched, by the under being weaker, and by the powerful structure of the 

 feet. The two outer toes also are almost equal. The three first species are aberrant, connecting this and the last 

 group. The typical species are found only in the tropics of America and India. 



Family, CINNYRID^. 



42. Genus, ANTHREPTES. 



Rostrum gracile, attenuatum, minute crena- Bill slender, attenuated, minutely crenated ; 



turn; mandibula inferior basi valida ejusque the base of the under mandible strong, and not
