Australian Birds in the Collection of the Linnean Society. 249 
Mr. Caley appends the following remarks to this species. 
“This bird appears to me to be a rare one, at least I 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 great Bat." 
Genus. SEÏISU RA*. 
Rostrum elongatum, subforte, valdè depressum, basi medioque 
latum, mandibulá superiore ad apicem subarcuata, sub- 
emarginatà ; naribus basalibus, ovalibus, setis plumulisque 
obsitis ; rictu setis brevibus parce instructo. 
Cauda elongata, patula, apice ferè æqualis. - 
Pedes mediocres, acrotarsiis scutellatis, paratarsiis integris. 
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 
* Sew quatio, and ovga cauda. 
* 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 
Musc. grisola only in being longer, the length being in proportion to that of the bill.
