and tension of. the bronchial tubes, widen the lateral diameter of the 

 lower larynx, and influence its position, coincides with the observa- 

 tions which Mr. Gould has made respecting the voice of the Tale- 

 galla; and at the same time establishes another important structural 

 diflerence between this bird and the Vulturidte, which are precisely 

 those Raptorial birds in which there are no true vocal muscles. 



" From all the Rapt ores the Talegalla essentially differs, in its 

 gizzard and elongated caeca : in the one we have all the characters 

 of the Gallinaceous structure of that important part of the digestive 

 system : in the form and proportions of the lower appendages — the 

 caeca, the Talegalla most closely corresponds with the genera Crax 

 and Penelope." 



Mr. Gould then exhibited some new species of birds about to be 

 figured in the forthcoming part of his work on the "Birds of Austra- 

 lia;" and characterised a new and beautiful Cinclosoma, from the 

 belts of the Murray, as 



Cinclosoma castanotus. Cincl. lined albd a mandihulee inferioris 

 basi per genas excvrrente : guld pectoreque nigris ; humeris et 

 uropygio castaneis. 



Total length, 9 inches; bill, 1 ; wing, 4^; tail, 4| ; tarsi, 1^. 



A new Halcyon, as 



Halcyon pyrrhopygia. Hal. plumis capitis viridibus, anguste 

 alba marginatis ; humeris tectricibusque alarum majoribus caru- 

 leis, uropi/gio, tectricibusque cauda flavescenti-rubris. 



Crown of the head dull green, intermingled with wlaite, giving it 

 a striated appearance ; a broad black stripe commences at the base 

 of the bill, passes through the eye, and encircles the back of the 

 head ; upper part of the back and scapularies green ; remainder of 

 the wings bluish green ; lower part of the back, rump, and upper 

 tail coverts red ; tail green, tinged with blue ; throat, a broad collar 

 encircling the back of the neck, and all the under surface white ; 

 bill black, the base of the lower mandible flesh white ; irides black- 

 ish brown ; feet dark olive brown. 



Total length, unc. 8 ; bill, 2 ; wing, 4 ; tail, 2^ ; tarsi, |. 



Hab. Interior of New South Wales. 



A new species of Rhipidura, which has hitherto been confounded 

 with the Motacilla fiabellifera of Latham, Mr. Gould proposed to 

 characterise as 



Rhipidura albiscapa. Rhi. nigrescenti-fusca ; rectricibus caudcs 

 ad apices, et per scapos albis. 



All the upper surface, ear-coverts, and a band across the chest, 

 sooty-black, slightly tinged with olive, the tail and crown of the 

 head and pectoral band being rather the darkest ; stripe over the eye, 

 lunar-shaped mark behind the eye, throat, tips of the wing coverts, 

 margins of the secondaries, shafts, outer webs and tips of all but the 

 two middle tail feathers, white ; under surface buff; eyes black ; bill 

 and feet brownish black.
