240 Mr. 0. Salvia on the Genus Leucopternis. 



plate representing Leucopternis semiplumbea in ' Exotic Ornitho- 

 logy.' The genus, as then understood by us, contained eight spe- 

 cies, which we divided into two categories — one, comprising seven 

 species, having the whole of the underparts white, and the other, 

 a single species, having those parts banded with white and lead- 

 coloured bars. The species which I now propose to describe 

 carries with it the bird usually known as Urubitinga schistacea 

 (Sundev.) ; and the two together form a third section of the genus, 

 having the whole of the underparts uniformly plumbeous in 

 colour. My remarks on these two species, and a further note on 

 L. princeps, form the principal subject-matter of this paper. For 

 all further details respecting the other members of the genus re- 

 ference must be made to the summary at page 121 of ' Exotic 

 Ornithology.' 



The new species I propose to call 



Leucopternis plumbea, sp. n. 

 Plumbea, alis extus et cauda nigricantioribus, hac fascia mediali 

 alba transvittata ; corporis lateribus et alarum pagina in- 

 feriore, prseter remigum apices, albis ; tibiis albo transfas- 

 ciatis : rostro plumbeo-nigro, cera aurantiaco-flava, pedibus 

 flavis: long, tota cir. 14"5 poll, angl., alse 9'4, caudse 5*8, 

 tarsi 2*5, dig. med. cum ungue 1'8, rostri a rictu 1*3. 

 Hab. in repub. ^Equatoriali. 



Obs. — L. schistacea similis, sed alis extus nigricantioribus et 

 intus albis, tibiis fasciatis et caudse apice nigro facile distin- 

 guenda. 

 The first primary in L. plumbea is about two inches shorter 

 than the longest, and nearly the same length as the secondaries; 

 the second primary is one inch and two tenths shorter than the 

 third, which is the longest in the wing, though the fourth and 

 fifth almost attain the same length ; the sixth is eight tenths of 

 an inch shorter than the fifth ; the seventh and eighth divide the 

 remaining space to the secondaries, which cover the tip of the 

 ninth primary : the white of the under wing is almost pure to- 

 wards the ulna, but towards the extremity of the inner pri- 

 maries becomes spotted with pale plumbeous. 



The wing-formula of L. schistacea hardly differs from that just 

 given, except that the third primary falls short of the fourth and 

 fifth by four tenths of an inch and is equal to the sixth.
