colour of the plnmage. It differs from l)olh by its pure white (not slaty greyish) 

 under wiug-coverts. The throat is variegated with white (tliis lieing sometimes 

 slightly indicated iu T. c. ylaucug), the ear-coverts show fine whitish shaft-lines, 

 and the edge of the wing is white, not slate grey as in T. c. glaucus. 



The S imm., sent liy M. Robert, and recorded s. n. T. caesium, exhibits the 

 same differences when compared with examples of T. c. qlaucus iu corn'spoudiiic 

 plnmage. 



The female of the Para form is not distiugnishable from the same sex of 

 T. c. caesius. 



The range of the three subspecies of Thnmnomnnes is as follows : 



a. T. c. caesius (Temm.) : Eastern Brazil : Bahia and Espiritu Santo (Wied), 

 west to the Rio Madeira (Salto do Girao, Natterer coll.), and the Rio Jnrud (Garbe 

 coll. ; spec, in Bins. Panlista examined). 



b. T. c. hoffmanyisi Hellm. : N.E. Brazil, vicinity of Para. 



c. T. c. glane/is Cab. : Cayenne, Brit. Guiana, Surinam, thence thrnngh the 

 Orinoco region (Mnnduapo, Caura R.) to the Rio Negro (Marabitanas, Rio Iganna, 

 Barcellos, Manaos), to Eastern Ecuador, E. Pern, and N.E. Bolivia (D'Orbigny 

 coll. — spec, in Paris Museum examined). Occasionally also found in Bogota 

 collections.

Sitta surinamensis Gmelin, fit/st. Xat. 1. i. (1788) p. 44'2 (ex Latham : " Surinam Nuthatch," Geii. 

 Syn. 1. ii. p. 654. tab. 28 (= ? )— Surinam). 



A single S ad., collected at Prata, 16. xi. 05. No. 138. " Iris brown." — 

 Wing 52 ; tail 25 ; bill 14 mm. 



It agrees perfectly with four <S d ad. from near Paramaribo (topotyjiical 



M. surinamensia). All have the lower mandible whitish, and tlie whole lower 

 surface striped with black. 



This is not only the first record of the species for Para, but also for tlie 

 Brazilian Avifauna. 



62. Myrmotherula cinereiventris cinereiventris Sd. k Salv. 



Cf. Nor. Zool. xii. (1905) p. 286. 



1 S ad., 1 S juv., 1 ? from Prata, 26. s., 15, 17. xi. 05. Nos. 20, 126, 146. 

 " Iris brown." 



The female agrees in the coloration of the underparts with others from 

 Cayenne, while the one sent by Robert is much darker underneath. 



63. Myrmotherula axillaris axillaris (Vieill.) 



Myrmothera axillaris Vieillot, Noiir. Dirt. xii. (1817) p. 113 (" La Guyane," sc. Cayenne).

 (No. 10). 



1 ? : 13. X. 05. No. 6. Iris brown. 



These specimens are in no way different from a good series of topotypical 

 Cayenne skins, having the sides of the l)elly snow-white. I examined the tyi)e of 

 T, melanogaiiter Spix, preserved in the Munich Bluseum, and fonnd it also to belong 

 to typical J/, axillaris. Tlie form of Eastern Brazil (from Pernambuco to Rio),
