Orn. pis. 49, 50; Burm. Syst. Ueb. ii. p. 377. Cinereus nigro maculatus, axil/is nigris, humeris pure albis tota 11, alar 8'3, caudar 5-2. Hab. Coast-region of S.E. Brazil, Caravellos, and Bahia (Max.). At once distinguishable by its small size and the snowy-white patch on the middle coverts. The only example I have seen of this species has been kindly lent to me by Mr. Eyton. I have not yet met with examples of two other species, which apparently valid, namely- 6. NYCTIBIUS BRACTEATUS. Nyctibius bracteatus, Gould, P. Z. S. 1846, p. 1 ; Cassin, Cat. Capr., et Pr. Acad. Sc. Philad. v. p. 184. Castaneo-fuscus, scapularium apicibus et abdomine maculis albis, quasi bracteis, ornatus : long, tota 9'5, alar 6, caudar (Gould). Hab. New Granada, Bogota. Mus. Reg. Inst, de Liverpool et Acad. Philadelphicse. This must be a scarce species. In the thousands of Bogota skins I have examined I have never met with it. 7. NYCTIBIUS RUFUS. Nyctibius rufus, Cab. in Schomb. Guian. iii. p. 711. Hab. British Guiana (Schomb.). Apparently well marked by its rufous general colouring and small size. Subfam. II. STEATORNITHIN.E. Of this subfamily there is only a single known representative, namely, STEATORNIS CARIPENSIS. Caprimulgus steatornis et Steatornis caripensis, Humboldt. Steatornis caripensis, l'Herminier, Ann. d. Mus. ser. 3. iii. p. 321, t. 15 ; E. C. Taylor, Ibis, 1864, p. 88. This remarkable bird was discovered by Humboldt and Bonpland in 1799, near the Mission of Caripe' in the province of Cumana, Venezuela. It also inhabits the caves beneath the ravine crossed by the celebrated " Natural bridge " of Pandi near Bogota, and the " Quebrada negra" of Guaduas in the same neighbourhood*, the chasm called the Hoyo del Aire, fourteen miles N.N.E. of Velez in New Granada f; and in all probability other similar localities in New Granada and Venezuela. * Rovdin, Compt.
