ing from all the other known members of that grouj) in having the 

 bill compressed laterally, for which reason I propose to constitute it 

 the type of a new genus, with the following name and characters. 



Genus Piezorhtnchus. 



Characteres generici. — Rostrum quam caput longius, altius plusquam 

 latum, fere cylindraceum, lateralitfer compressum, apicem versus den- 

 ticulatum. Nares parvae, rotundatse, basales. Ala breves, remige 

 primo mediocri, quarto longissimo. Cauda aliquanto brevis et rotun- 

 data. Tarsi mediocriter elongati et paulo debiles. Digitus ex- 

 ternus et medius inter se connexi usque ad articulum primum, ex- 

 ternus longissimus. 



The only specimen I possess w^as forwarded to me by E. Dring, 

 Esq., surgeon of H.M.S. Beagle, by whom it was procured on the 

 north-west coast of Australia. From the glossy nature of its plu- 

 mage I propose to name it 



PiEZOKHYNCHUs NiTiDUS. Piez./ulgide viriscenti-niger. 



All the plumage, including the wings and taU, rich deep glossy 

 greenish-black ; biU and feet black. 



Total length, 7^ inches; bill, 1^; wing, 3 1; tail, 3|; tarsi, |, 



Hab. North-west coast of Australia. 



This very curious bird belongs, I conceive, to the Muscicapidce, 

 and is somewhat allied to Seisura. 



A new Praticola, common on the plains round Adelaide, and form- 

 ing the second example of the genus, is 



Praticola campestris. Prat, fronte et plumis auricularibus rufis ; 

 gutture albescente ; corpora subtus et lateribus ex arenaceo luteolis 

 fusco striatis. 



Forehead rufous, passing into tlie reddish brown of the crown and 

 upper surface, with a stripe of blackish brown down the centre of 

 each feather ; wings sandy brown ; internal webs of the primaries 

 dark brown ; two centre tail-feathers reddish brown, the remainder 

 reddish bro-wTi at the base, crossed towards the extremity with a broad 

 band of brownish black and broadly tipped with white ; over the eye 

 a line of white ; ear-coverts mingled rufous and white ; throat white, 

 gradually passing into the buff of the under surface ; all the feathers 

 of the under surface with a stripe of brownish black down their 

 centre ; bill blackish, lighter at the base of the under mandible ; 

 irides rufous brown ; feet blackish brown.
