the belly : the tail is even, each feather being mucronate : feet 

 pale. I doubt not that this is the representation of the genus 

 Ptilochloris, in the neighbouring circle of Vereoiiife. 



223. Crypticus super ciliosus. 



Above^ olive green : ears, inter scapulars_, and under 

 plumage, rufous : stripe beneath the ear, and down the 

 middle of the throat, black ; the latter bordered with 

 blue : crown margined by a broad superciliary stripe of 

 beryl colour : tail and secondaries blue, broadly tipt with 

 black. 



Inhabits Spanish America. Mus. Nost. Momotus 

 super ciliosus. Liverpool Institution. 



Total length 14 inches ; bill, gape lj| ; front U ; wings 4| ; 

 lateral tail feathers, beyond, 2 ; middle tail feathers, from the 

 base 8| ; naked part of the shafts 2i. This is the second spe- 

 cies of this remarkable subgenus now known. The narrow 

 black stripe beneath the ears takes its rise from the orbits, and 

 extends halfway down the neck, having a small line of blue at 

 its inner edge, just beneath the eye and orbits : the black 

 stripe down the throat begins at the chin, and ends at the breast : 

 middle of the crown olive green : the spatules of the two 

 middle tail feathers are very large, and the terminal half are 

 deep bl^ck : the lateral tail feathers are tipt with deep black, 

 and graduated : the beryl green stripes over the eyes are par- 

 ticularly large and brilliant. 



224. Cassicus latirostris. 



Bill broader than high. Plumage black : head and 

 neck, above, chestnut : lateral tail feathers yellow, tipt 

 with black. 



Inhabits Peru. Mr. W. Hooker's Collection. 



Total length about 12 inches; bill, gape 1^^; front Ij^g; 

 breadth of the frontlet -f^; wings 7 ; tail, base 4^; tarsus l-f^. 

 The remarkable form of the bill in this new and singular spe- 

 cies deserves particular attention, because it is evidently a mo- 

 dification of that broad and depressed structure which belongs 

 to the fissirostral type, and to its representatives, throughout 

 this class. The frontlet advances far upon the forehead, and is 

 there so much dilated as to be three times as broad as this man- 

 dible is in depth, which consequently becomes remarkably de- 

 pressed ; the under mandible is much thicker than the upper ; 

 and both, on their terminal half, are suddenly narrowed and
