6. Sub-genus (?), ERUCIVORA. 



Rostrum longiusculum, medio compression. Bill rather lengthened, compressed in the 



Rictus Icevis. Alee mediocres, remigibus middle. R ictus smooth. Wings moderate;

graciles, longiusculi ; digitus externus et in- rigid. Tarsus slender, somewhat lengthened ; 



ternus sub-cequales. the outer and inner toe nearly equal. 



Type. — Turdus orientalis, Auct. (Saxicola orientalis, Cuv. Mus. Paris.) 

 Obs. — I have many doubts both as to the value of this group, and its precise situation among the Ceblepyrince. It is 

 distinguished from all others I have yet seen, by its more lengthened and compressed bill ; by the greater elevation of 

 its tarsi, and by the softness or flexibility of its rump feathers. Judging theoreticallv, as these characters are the most 

 aberrant I have yet seen, they might be supposed to indicate that genus which represented the tenuirostral type, parti- 

 cularly as the following is manifestly the representation of Prionops, Vieill., Dasycephala, Swains., &c. 



7. Genus, OXYNOTUS.

 ungues magni valde curvati. rigid. Tarsi strong ; the claws large, and 



much curved. 

 Type. — Lanius rufiventer, Mus. Paris. 

 Obs. — There is a general resemblance between this very singular bird and the genus Sphecotheres, Vieill., in the 

 bill and tarsi ; but the two forms are clearly analogical. We originally proposed the name of AcantMnolus for this 

 genus, but the word has been already employed in Entomology.
