Salvin (I. c, 1886, p. 59) from Bartica Grove, Merum6 Mountains, and 

 Roraima; by Chubb (I. c, p. 483) from Anarika River, etc., giving range 

 in Br. Guiana; and by Dawson (I. c, p. 24). 



Thamnophilus amazonicus Sclater. — Schomburgk (I. c, p. 687) 

 states that it inhabits the low bushes of the coast woods. It has been 

 recorded by Salvin (I. 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 (I. 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 9 ?]. 



Dysithamnus schistaceus (d'Orbigny). F. P. and A. P. Penard 

 (I. c, 1910, ii, p. 308) state that there are specimens in the Museum at 

 Georgetown. Dawson (I. c, p. 26) lists it as a Colonial species. 



Automolus infuscatus Sclater. — Recorded by Salvin (I. 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 Auto- 

 molus 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 abso- 

 lutely 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 (I. 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 d 1 from Ourumee. 



Xiphorhynchus guttatoides (Lafresnaye) . — The form guttatoi- 

 des of Colombia, is a subspecies of Xiphorhynchus guttatus Lichtenstein, 

 of which the race inhabiting Br. Guiana is X. g. sororius (Berlepsch and 

 Hartert), type locality Perico, Orinoco River. Berlepsch and Hartert 

 (Nov. Zool., 1902, ix, p. 63), who originally described this form as Den- 

 drornis rostripallens sororia, mention a specimen from Quonja, Br. Guiana,
