"Eyes brown, legs yellow, cere yellow, bill blue; stomach had remains of small birds." 715, 71 ti, females, Elizabeth Island. " Eyes brown, legs yellow, cere yellow." These specimens all belong to the form kept distinct by Mr. Sharpe (Cat. Birds, i. p. 439) under Swainson's title cinnamominus. But when a large series is examined, we find so many intermediate forms between T. cinnamominus on the one hand, and T. isabellinus on the other, that it seems better to keep these three continental forms all under one specific designation. On the other hand, the insular forms T. leucophrys and T. spm'verioides of Cuba, and T. dominicensis of the other Antilles, seem to be fairly distinct. 24. MILVAGO CHIMANGO (Vieill.); ScI. et Salvo Nomencl. p. 122. 669, 670, females, Porto Bueno. "Eyes brown, feet bluish grey." 695, male, Sandy Point. " Eyes brown, bill yellowish tinge, legs blue." 25. POLYBORUS THARUS (MoL); ScI. et Salvo Nomcllcl. p. 123. 679, male, Isthmus Harbour. "Eyes brown, bill blue, cere flesh-coloured, and legs fleshcoloured." 684, male, Port Churrucha. "Eyes brown, cere orange, legs yellow, bill bluish tinge." 26. CATHARTES AURA (Linn.); ScI. et Salvo Nomencl. p. 123. fEnops falklandica, Sharpe, Cat. Birds, i. p. 27, pI. ii. i31, female, Falkland Islands. " Eyes brown; had remains of birds in the stomach." We consider Mr. Sharpe's generic and specific names for this V ulture alike unnecessary. !lliger, in his' Prodromus' (1811), gave two types for his genus " Cathartes," VultUl' papa and V. aura. In 1816 Vieillot made two genera, Gypa.Cfus for V. papa and Catharista for VUltU1' aura and V. atl'atus. Cathal'tes, however, has been generally userl for the latter group; and there is, in our opinion, no reason whatever for transferring it hack to the former, which has au excellent and appropriate name in Gypagus. There seem to us no sufficient characters to separate the red-headed and black-headed species of Cathartes into two genera. As regards the Falkland-Island form of C. aura, which Mr. Sharpe designates fEnops falh:landica, the differential character relied upon, which is, apparently, merely the slight greyish-brown margination of the secondaries, appears to us to be insufficient, |
