running from the cap towards the breast ; legs fleshy ; bill horn- 

 yellovv, darkened on ridge ; iris pale orange. 



2nd species, -S. pyrops, mihi. — 01ive-brown above, sordid rūsty 

 below and on the sides of head and neck ; beneath and before the eye 

 and under the chin a black spot ; bill sordid sanguine, dusky on the 

 ridge ; legs horn-colour ; eye sanguine. 4^ inches long ; bill, ^ ; 

 tail, 2 ; tarse, | ; centrai toe and nail, -^^ ; hind, -^ ; wing, 2. 



3rd species. S. chrysceus, mihi. — Above vernal green, deeply tinged 

 with golden ; below brigbt golden ; cap with dusky stripes ; bill 

 dusky ; legs yellow. Length, 4^ inches ; bill, ^ ; tail, 2 ; wing, 2^ , 

 tarse, | ; centrai toe and nail, \ ; hind, -į^. 



Remark. — These singular birds belong I think to Swainson's group 

 of the BrachypodiruB, among the creeping genera of that group ; but 

 they show some tendency to pass to the Leiotrichanians, by means 

 of Pteruthius and our Heteromis ; Heteromis at all events mušt take 

 place next Fteruthius ; but I think the true position of Stachyris is 

 among the Brachypods, near to lora and Icteria, with the forms 

 that we shall next give, and leading to the Crateropodans. 



Genus Misomis, mihi. 



General structure of lora, but the bill quite diflferent and Meruline ; 

 commissure and culmen subarched throughout ; tarse lovver and not 

 exceeding the large thumb with its nail ; tail fully rounded. Type, 

 M. ruficeps, mihi. — Timalia gularis of Horsfield ? 



M. rttjiceps. — Body vernal green, passing to yeUow on the throat 

 and breast, \vhere also there are dark lines down the shafts of the 

 plumes ; cap, wing and tail brunescent ; bill bluish horn ; legs fleshy 

 grey ; iris hazel. Length 5| inches ; bill, į ; tail, 2^ ; tarse, J-| ; 

 centrai toe and nail, ^; hind, -^•, closed wing, 2|. Sexes alike. 



Genus Erpornis. 



General structure of the lašt, but the bill very straight, compressed, 

 with the culmen -vvell-raised and keeled between the nares, as in Sta- 

 chyris and in lora, but less thick and rounded and the notch more 

 remote than in lora ; vings longer and more acuminate, with the 

 first three ąuills less equally gradated ; legs smaller ; tail even. 



Type, Erpornis xanthochlora, mihi. — Above vernal yellow, below 

 white ; legs and bill fleshy grey ; iris bro'vvn. Five inches long ; bill, į ; 

 tail, 2^; closed \ving, 2f ; tarse, \^; centrai toe and nail, ^; 

 hind, ^. Sexes alike. 



Remarks. — The above two forms are much related to each other, 

 as well as to Stachyris and the other Brachypodan clinging-birds ; but 

 Miromis inclines towards Timalia among the Crateropodans, while 

 Erpornis is nearer to Stachyris and Zosterops, which lašt I consider 

 to be a Brachypod. Both inhabit the lower and centrai hills, and 

 feed on tiny tree-insects and their larvae and pupae. Their tongue 

 is simple. 



Genus Ixulus. 



General structure of Polyodon, but the bill, tongue and nares sim-
