A new species from Swan River, which, with the Muscicapa ma- 

 cropteru of Messrs. Vigors and Horsfield, I propose to erect into a 

 new genus under the name of Microeca. 



Genus Micrceca. 

 Characteres generici. — Rostrum quam caput brevius, depressum, ad 



basin latum, gonyide recto, apice incurvo et le\'iter denticulato. 



Nares rotundatse, ad basin rostri vibrissis validis instructam 



positse. Ala longag et fortes, remigum primo brevi, tertio lon- 



gissimo, Cauda aliquanto brevis, et fere quadrata. Tarsi medio- 



cres, debiles. Digiti debiles ; externus quam internus valde lon- 



gior. 



As the species now exhibited closely assimilates to the M. ma- 

 croptera, I propose to designate it as 



Micrceca assimilis. Mic. superne, caudce rectricum exteriiorum po- 

 goniis internis per partes tres longitudinis a basi fuscis. 



All the upper surface brown ; primaries dark brown ; tail brown- 

 ish black, the tips and the terminal half of the external margins of 

 the two outer feathers white, the three next on each side are also

 feathers without the white tip ; throat, centre of the abdomen and 

 under tail-coverts white, passing into pale brown on the sides of the
