pically Crateropodan, with a high strong tarse; toes medial, unequal, 
central not elongated, laterals unequal, 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 
rusty brown on the alars, caudals, brows and chin, and the former 
(typically) marked with 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, 
83 inches; bill, 2; tail, 42; wing, 35; tarse, 14; central toe and 
nail, +3; hind, 14. 
Remarks.—These birds form one of those singular links which 
unite the Crateropodan and Brachypodan thrushes with the Meli- 
phagide, of which last 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 Iwops there is little trace of it. «ops leads from a Meli- 
phagian type (Alcopus) to the Crateropods, and Jzulus from another 
(Polyodon) to the Brachypods.
