Ceryle americana americana (Gmelin). Recorded by Salvin (l. c., 1886, p. 60) from Bartica Grove and other localities; by Sharpe (Cat. Birds Br. Mus., 1892, xvii, p. 139) from Demerara River; by Chubb (l. c., p. 348) from Bonasika River, etc., giving range in Br. Guiana; and by Dawson (l. c., p. 16).
Cypseloides fumigatus Streubel. —F. P. and A. P. Penard (l. c., 1910, ii, p. 95) state that there are specimens in the Georgetown Museum, and Dawson (l. c., p. 34) lists it as a Colonial species.
Tapera nævia (Linné).—Schomburgk (Reis. 1848, iii., p. 713, sub nom. Diplopterus galeritus) says that it is abundant in coast regions. Quelch (Timehri, 1891, p. 95; Reprint, p. 27) speaks of it as common in Georgetown; and Percival (l. c., p. 9) states that its frequent plaintive note “Wife-sick” is one of the most familiar garden sounds. It has also been recorded by Salvin (l. c., 1886, p. 64) from Bartica Grove and Roraima; by Shelley (Cat. Birds Br. Mus., 1891, xix, p. 423) from Georgetown; by Chubb (l. c., p. 443) from Ituribisi River, etc., giving range in Br. Guiana; and by Dawson (l. c., p. 23). The Br. Guiana form stands, Tapera nævia nævia (Linné).
Pteroglossus aracari aracari (Linné). —Schomburgk (l. c., p. 720) states that the species is tolerably abundant in Br. Guiana. It has been recorded by Salvin (l. c., 1886, p. 65) from Bartica Grove; by Sclater (Cat. Birds Br. Mus. 1891, xix, p. 138) from Demerara; by Chubb (l. c., p. 458, sub nom. Pteroglossus roraimæ) from Roraima etc., giving range in Br. Guiana; and by Dawson (l. c., p. 22). The form inhabiting Br. Guiana is P. a. atricollis (P. L. S. Müller)—see Bangs and Penard (Bull. M. C. Z., 1918, p. 55).
Chloronerpes rubiginosus (Swainson). —Schomburgk (l. c., p. 715) says he found it throughout Br. Guiana. It has been recorded by Salvin (l. c., 1886, p. 59) from Bartica Grove, Merumé Mountains, and Roraima; by Chubb (l. c., p. 483) from Anarika River, etc., giving range in Br. Guiana; and by Dawson (l. c., p. 24).
Thamnophilus amazonicus Sclater. —Schomburgk (l. c., p. 687) states that it inhabits the low bushes of the coast woods. It has been recorded by Salvin (l. c., 1885, p. 423) from Bartica Grove and Camacusa; by Sclater (Cat. Birds Br. Mus., 1890, xv, p. 199) from Takutu River (Salvin-Godman coll.); by Quelch (Animal Life in Br. Guiana, 1901, p. 182); and by Dawson (l. c., p. 26), who stars the species, indicating that there are no representatives in the Museum at Georgetown. All these authors, except Sclater, refer to this species as Thamnophilus ruficollis [= amazonicus ♀].
Dysithamnus schistaceus (d’Orbigny). F. P. and A. P. Penard (l. c., 1910, ii, p. 308) state that there are specimens in the Museum at Georgetown. Dawson (l. c., p. 26)lists it as a Colonial species.
Automolus infuscatus Sclater. —Recorded by Salvin (l. c., 1885, p. 420, sub nom. Automolus sclateri), from Bartica Grove, stating that the specimens are rather smaller than those from the type locality, with faint indication of striation on the throat; and by Sclater (Cat. Birds Br. Mus. 1890, xv, p. 95, sub nom. Automolus sclateri) from Camacusa and Bartica Grove. Automolus sclateri (Pelzeln) is a pure synonym of Automolus infuscatus Sclater, having been proposed by Pelzeln (Orn. Bras., 1867, i. p. 41) on the assumption that the name Automolus infuscatus was preoccupied by Anabates infuscatus Bonaparte, which, however, proves to be a nomen nudum (Cf. Hellmayr, Nov. Zool., 1905, xii, p. 279). Mr. Beebe lists both infuscatus and cervicalis, apparently considering them two distinct species, the former only being starred as new to the Colony. Hellmayr (Nov. Zool., 1906, xiii, p. 335) says that “the specimens of Automolus sclateri from British Guiana in the British Museum are absolutely identical with the type of P. cervicalis,” and states that the type of P. cervicalis is an immature bird. He lists the Guiana form, which differs from true infuscatus, as Automolus infuscatus cervicalis (Sclater), type locality “Camacusa and Bartica Grove.”
Apparently, then, records of A. infuscatus, A. sclateri, and A. cervicalis, in Br. Guiana, apply to the same bird.
Sclerurus rufigularis Pelzeln. —Hellmayr (Nov. Zool., 1906, xiii, p. 364) mentions an immature bird from Takutu River, Br. Guiana, and says (l. c., p. 365) that there is a specimen in the British Museum collected by Whitely at Bartica Grove. He also says that the Br. Guiana Museum has a ♂ from Ourumee.
