34. Philydor pyrrhodes (Cab.) 



Anabates pyrrhodes Cabauis : ia Schomburgk, Beisen Brit. Guiana iii.(1848) p. G89 (coast of British 

 Guiana). 



No. 456. c? iinru., Itaituba, 10. i. 06. -'Iris brown."— Wing 89; tail 69; 

 bill 18 mm. 



This bird is indistinguishable from a British Guiana specimen, while others 

 from the Orinoco River arc much deeper ochraceous below, and a little more 

 mfescent on the back. 



35. Xenops genibarbis HI. 

 Cfr. Nov. Zool. xiii. p. 366. 



No. 42T. ? imm., Itaituba, 11. i. 06. " Iris browu." 



Slightly different from a Para skin. I hope to discuss the various geographical 

 races of X. genibarbis on another occasion. 



36. Dendromis eytoni (Scl.) 



Ofr. Nov. Zool. xii. (1905) p. 283. 



Dendrornit eytoni Riker & Chapman, Auk, 1891, p. 27. 



No. 524. $ ad., Itaituba, 31. i. 06. " Iris brown, bill greyish black."— Wing 

 116; tail 106 ; bill 42 mm. 



Agrees well with Para examples, but is perhaps a shade more rusty on the 

 abdomen. The basal half of the lower mandible is dirty yellowish. 



37. Dendroplex picus (Gin.) 



'us Picus Gmelin, Syst. Nat 1. ii. (1788) p. 384 (ex Daubenton, Pl.enl. 605.— Cayenne).

No. 477. ? ad., Itaituba, 21. i. 06. " Iris pale brown."— Wing 100 ; tail 87; 



bill 34 mm. 



Agrees best with specimens from Barcellos and Obidos, collected by Natterer, 

 being not appreciably different from topotypical Cayenne skins. About the 

 geographical variation of I>. picus cfr. Meuegaux & Hellmayr, Man. Soc. Hist. 

 Mat. Autun xix. (1906) pp. 108—109.

 12. ii. OH. " Iris reddish brown." 



Apparently not different from Orinoco specimens. The Tring Museum 

 possesses also a young bird, collected by Prof. Steere near Camolins, Lower 

 Amazons.
