134 MR. E. BLYTH ON A HYBRID CHAMOIS. [Feb. 11, 
Rupornis gularis, Licht. Nomencl. p. 3. 
Asturina gularis, Schlegel, Mus. des P.-B. Asturine, p. 4 (1862). 
Supra obscure fusca: capite toto cum gutture obscurioribus : 
pectore et ventre toto cum tibiis pallide fulvis, lineis angustis 
ferrugineis parce transfasciatis : cauda nigricante, rufo late 
trivittata et terminata. 
Hab. Buenos Ayres (Schlegel) ; Corrientes (D’ Orb.) ; Paraguay 
(Azara) ; Bolivia (Bridges) ; prov. Yungas (D’Ord.). 
In speaking of his so-called Astur magnirostris, D’Orbigny (J. s. ¢.) 
calls especial attention to the differences between his series of this 
bird from Corrientes and Bolivia and that in the Paris Museum from 
Brazil, and concludes that they form “two distinct and constant 
varieties.” We have little doubt that it is to this so-called variety 
that Lichtenstein applied the name gularis, afterwards adopted by 
Schlegel in his ‘ Musée des Pays-Bas.’ 
But this term must, we think, give way to that of pucherani, 
under which the MM. Verreaux described a species of Asturina in 
1855. A mounted specimen belonging to the Norwich Museum is 
marked as the original of this description in the handwriting of M. 
Jules Verreaux, and perfectly accords with the characters given. 
We believe we are correct in referring it to the immature dress of 
the present species. A nearly similar specimen is in the British 
Museum, also received from Verreaux, under the name Asturina 
pucherani, but with ‘ Guatemala” attached as a locality. This is 
probably an error, as it does not correspond with any one of our ex- 
tensive series of the Central-American form, which is 4. ruficauda. 
The only adult example we have yet seen of this bird is in the 
British Museum. It was obtained in Bolivia by Bridges.

4. On the Hybrid between the Chamois and the Domestic 
Goat. By Epwarp Bryra. 
Upon a recent occasion (cf. P. Z. S. 1868, p. 623) I exhibited 
four pairs of horns which puzzled me exceedingly at first, but which 
I learn from Mr. Joseph Wolf are those of hybrids raised from the
