Australian Birds in the Collection of the Linnean Sociefi/. 249 



Mr. Caley appends the following remarks to this species. 

 " This bird appears to me to be a rare one, at least 1 do not 

 recollect having ever seen any other specimen than the present. 

 I met with it on the 15th of October 1807 at Cardunny, a place 

 about ten miles to the north-east of Paramatta. It is a thick 

 brush (or underwood), and is the resort of the gi-cat Bat."

This group bears a very close resemblance to the latter in the 

 form of its tail, and we consequently expect to find in it a simi- 

 larity of habits. In this expectation we shall not be disap- 

 pointed, as the concurrent testimony of all the eye-witnesses of 

 the manners of the bird which forms the type of the genus 

 represents it as being an active and restless bird, moving its tail 

 when in quest of insects like the European Motacilla, and 

 spreading it out like the preceding group of Rhipidura when it

t The tongue of the type of this genus, of which a specimen was fortunately at- 

 tached to one of the birds in the Society's collection, differs from that of the European 

 Muse, grisola only in being longer, the length being in proportion to that of the bill.
