ple^ and Brachypodan, not Meliphagian ; bill short and singly notched 

 at the tip. 



Type, Polyodon flavicollis or Yuhina flavicollis, as printed. 



Remark. — Polyodon is a strictly Meliphagian fonn. la^ulus is one 

 of the genera serving to connect the true Honeysuckers with the re- 

 pent Brachypods, such as Zosterops, Chloropsis, &c., and w'hich are 

 so likę the former. 



Crateropodin^. 



Genus Py et oris, mihi. 



Bill short, strong, perfectly entire, arched throughout the culrainal 

 and tomial lines ; nareal fosse and scale obsolete ; rietus ■with very 

 strong short bristles ; orbits nude ; wings short and feeble, the first 

 two quills much, the next two little gradated ; third pair equal and 

 longest ; tail long, broad and gradated throughout ; legs and feet ty- 

 pically Crateropodan, with a high strong tarse ; toes medial, uneąual, 

 centrai not elongated, laterals uneąual, hind large ; nails large, but 

 not much curved nor acute ; hind one largest. 



Type, Timalia hypoleucos, Auct. 



Hab. The plains only, represented in the hills by Deceira. 



A. rufifrons, mihi. — Above sordid ashen olive, passing to clear 

 rūsty brown on the alars, caudals, brows and chin, and the former 

 (typically) marked \vith frequent regular cross-bars of black ; tail 

 longer and more gradated than in Nipalensis ; head similarly crested ; 

 bill and feet embrowned fleshy or horny grey ; iris brown. Length, 

 8| inches ; bill, į ; tail, 4| ; \ving, 3į ; tarse, \\ ; centrai toe and 

 nail, J-|; hind, ^. 



Remarks. — These birds form one of those singular Imks which 

 unite the Crateropodan and Brachypodan thrushes ■vvith the Meli- 

 phagida, of ^vhich lašt our Alcopus is a true member, having the 

 brushed tongue in perfect development. Zosterops, Chloropsis, 

 Hypsipetes, &c. of the Brachypodan group, likewise have the brushed 

 tongue in more or less development, but not so perfectly as in Al- 

 copus. In Ixops there is little trace of it. Ixops leads from a Meli- 

 phagian type (Alcopus) to the Crateropods, and Ixulus from another 

 {Polyodon) to the Brachypods. 



Mtotherin^. 

 Genus Pnoepyga (olim Tęsia), mihi. 



Bill short, straight, Cinclosyhdan, depressed as far as the nares, 

 compressed beyond, ^vith inflexed tomia and tip faintly inclined and 

 notched ; nares large, fossed, unplumed, furnished with a salient 

 membranous scale, which lunates the aperture ; rietus and brows 

 smooth ; ■tt'ings very short, bowed, and perfectly rounded ; tail rudi- 

 mentary, consisting of only six jilumes, ■vvhich are hid by the pufiy 

 rump-feathers ; legs and feet ambulatory ; tarse elevate, smooth ; 

 lateral toes equal. Types, the follovving : —
