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'Orb.). In speaking of his so-called Astur magnirostris, D'Orbigny (7. s. ci) 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." W e have little doubt that it is to this so-called variety that Lichtenstein applied the name gularis, afterwards adopted by Schlegel in his ' Musee des Pays-Bas.' But this term must, we think, give way to that of pucherani, under which the M M . 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. W e 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 extensive series of the Central-American form, which is A. ruficauda. The only adult example we have yet seen of this bird is in the British Museum. It was obtained in Bolivia by Bridges. 7. ASTURINA LEUCORRHOA. Falco leucorrhous, Q. et G. Voy.

By E D W A R D BLYTH. 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 |
