Show 1866.] MR. SCLATER ON THE AMERICAN CAPRIMULGIDcE. 137 Caprimulgus cortopao, Natt. Mus. Vindob. sp. no. 741. Hab. Cayenne (Buff.); Para (Natt.). I have a single female example of this species, from Natterer's collection. Mr. Salvin's collection also contains a specimen. 3. ANTROSTOMUS SERICEO-CAUDATUS. Antrostomus sericeo-caudatus, Cassin, Proc. Acad. Phil. iv. p. 238, et Journ. ii. p. 121, pi. 12. Hab. South America. I have a skin, believed to be from Venezuela, which I think may probably be referable to the female of this species. There is a similar specimen in the British Museum, said to be from Bahia. 4. ANTROSTOMUS VOCIFERUS. Caprimulgus vociferus, Wils. Antrostomus vociferus, Cassin, Journ. Ac. Phil. ii. p. 122 ; Baird, B. N. Am. p. 148. Hab. Eastern United States to the plains (Baird) ; Cuba (Lem-leye) ; South Mexico, Jalapa (De Oca) ; Guatemala (Salvin). This species seems to be abundant in Guatemala. Mr. Salvin obtained examples at Coban and San Geronimo, besides other localities in Vera Paz, 5. ANTROSTOMUS MACROMYSTAX. Caprimulgus macromystax, Wagl. Isis, 1831, p. 533 (?). Antrostomus macromystax, Sclater, P. Z. S. 1858, p. 296. Similis A. vocifero, sed paulo major, alis longioribus, rostro lon-giore et magis compresso : narium aperturis exstantibus ; tarsis longioribus et magis denudatis : long, tota 9*7, alar 6*6, caudar 5, rostri a rictu lin. dir. 1*4. Hab. In Mexico merid. La Parada (Boucard). Whether this bird is really Wagler's C. macromystax is certainly problematical; but there is no doubt at all of its being quite distinct from A. vociferus, although at first sight it is surprisingly like that species in coloration. I have not yet met with a second example of this species. 6. ANTROSTOMUS NUTTALLI. Caprimulgus nuttalli, Aud. Antrostomus nuttalli, Cassin, Journ. Acad. Phil.ii. p. 123; Baird, B. N. A. p. 149 ; Coues, Ibis, 1865, pp. 158 et 538 ; Dresser, ibid. p. 470. Hab. High central plains of North America, extending to the Pacific Coast ; Kansas and Arizona (Coues) ; Texas (Dresser). Easily distinguishable from A. vociferus by its smaller size. It appears also, judging from the specimens in my collection, to have nearly the whole tarsus bare of feathers. 7. ANTROSTOMUS OCELLATUS. Caprimulgus brasilianus, Max. Beitr. iii. p. 337. |
