species differing considerably in several of its characters from the 

 Brush Turkey {Talegalla), Mr. Gould proceeded to characterize it 

 as a new genus, under the name of Leipoa, signifying * a deserter of 

 its eggs/ The specific term of ocellata was suggested by the ocel- 

 lated character of many of the spots with which its body is adorned. 



Genus Leipoa. 



Gen. Char. — jRo^^rwrn fere tarn longum qiiam caput; gracile, ad 

 basin tumescens, tomiis undulatis et ad basin incurvatis, naribus 

 amplis, oblongis, operculo tectis, et in fovea central! positis. Caput 

 subcristatum. Alee amplae, rotundatse, concavse ; e remigibus pri- 

 mariis quinto longissimo ; tertiariis qukm remiges primarii fere tkm 

 longis. Cauda rotundata, rectricibus quatuordecem. Tarsi mediocres, 

 robusti, antice scutis, postice squamis rotundatis baud sequalibus, 

 tecti. Digiti subbreves ; digitis lateralibus inter se fer^ sequalibus. 



Leipoa ocellata. Lei. pectore per medium plumas lanceolatas 

 nigras, strigd centrali albd ornatas, prcehente, plumis corporis su- 

 perne albescenti-cinereis, ad apicem guttdpene ocellatd, rufd, nigra 

 marginatd, notatis. 



Head and crest blackish brown ; neck and shoulders dark ash gray ; 

 the fore part of the former, from the chin to the breast, marked by 

 a series of lanceolate feathers, which are black with a white stripe 

 down the centre ; back and wings conspicuously marked with three 

 distinct bands of grayish white, brown and black near the tip of each 

 feather, the marks assuming an ocellate form, particularly on the 

 tips of the secondaries ; primaries brown, their outer webs marked 

 with zigzag lines of darker brown ; rump and upper tail -coverts 

 brownish gray, the feathers of the latter transversely marked with 

 two or three zigzag lines near their tip ; all the under surface light 

 buff, the tips of the flank feathers barred with black ; tail blackish 

 brown, broadly tipped with buff; bill black ; feet blackish brown. 



Total length, 24 inches; bill, Ij; wing, 12; tail, 8^; tarsi, 2^. 



Hab. Western Australia. 



Mr. Gould next proceeded to characterize the two following new 

 birds : — The first (Cracticus argenteus) is from the collection of Capt. 

 Gray, and the second, a new species of Amadina, is from the collec- 

 tion of Mr. Dring, of H. M.S. Beagle. 



Cracticus argenteus. Cra. guld corporeque subtils albis ; humeris 

 nigris ; dor so argenteo-cinereo. 



Crown of the head, ear-coverts, shoulders, primaries, and all the 

 tail-feathers for three-fourths of their length from the base, black ; 

 back silvery gray ; throat, all the under surface, sides of the neck, 

 some of the wing-coverts and the margins of several of the second- 

 aries, rump, and tips of the tail-feathers pure white; bill horn- 

 colour ; feet blackish brown. 



Total length, 11 inches; bill, l^; wing, 6; tail, 4| ; tarsi, 1;J^. 



In size this species is directly intermediate between Cracticus ci- 

 nereus and C. varius. 



Hab, North-west coast of Australia.
