This bird, although of a large size and so sombre in colouring, is 

 nearly allied to Petro'ica. 



The next is an extraordinary form among the Muscicapidce, differ- 

 ing from all the other known members of that group in having the 

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

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



Genus PlEZORHYNCHUS. 



Characteres generici. — Rostrum quam caput longius, altius plusquarn 

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

 ticulatum. Nares jiarvse, rotundatae, basales. Alee breves, remige 

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

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

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

 temus longissimus. 



The only specimen I possess was 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 



PlEZORHYNCHUS NiTiDUS. Piez. fulgide virescenti-niger . 

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

 greenish-black ; biU and feet black. 



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

 Hab. North-west coast of Australia, 



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

 and is somewhat allied to Seisuru. 



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 ulbescente ; corpore svbtus et lateribus ex arenaceo luteolis 

 fusco striatis. 

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