as />. temmincki, and, as his name has the priority by fonr years, the latter 

 species has to stand in future as Dendrexetastes rufigula (Loss.). 



The range of the two species of Dendrexetastes* is, according to our present 

 knowledge, as follows : 



a. IK rufigula (Less.). Cayenne; Surinam: near Paramaribo (Chunkoo coll.) f ; 

 British Guiana : Mines district f ; North Brazil : Barra do Rio Negro (Natterer). | 



b. J). (Iccillci (Des Mars). Eastern Pern : Sarayacn (Casteluau and Dcville), 

 Iquitos (Whitely), Samiria (Hauxwell) ; N.W. Brazil : Humaytha, Rio Madeira 

 (Hoffmanns). 



1>. dexilhi is thus for the first time recorded from Brazil.

 Cf. sttpri, p. 16. 

 Nasica longirostris Pelzeln, Zur Ornith. Bras. i. 18G7. p. 44 (Salto do Girao, Borba). 



Nos. 1174, 1184. c? ad., ? ? imm., Humaytha, 27, 20. viii. 06. "Iris light 

 brown, feet grey, bill greyish yellow." 



Nos. 1341, 1443. ? ad., ? juv., Borba, 10. xi., 4. xii. 06. "Iris brown or

69. Xiphornis procurvoides (Lafr.) or snbsp. ? 



Xiphorhynchus procurvoides Lafresnaye, Rev. Mag. Zool. 1850. p. 376 (Cayenne). 

 X. trochilirostris (nee Lcht.) Pelzeln, Zur Orn. Bras. i. 1807. p. 44 (part. : Borba). 



No. 1442. ? ad., Borba, 4. xii. 06. " Iris brown, feet plumbeous, bill 

 brownish red." — Wing 95 ; tail 91 ; bill 65 mm. 



This specimen differs from typical Cayenne skins and others from British 

 Guiana by being rather more olive on the lower parts, and by having the creamy 

 shaft-stripes on the foreneck and chest laterally margined with black. The 

 dusky edges to the throat-feathers, too, are less numerous and less distinct. A 

 series from the Rio Madeira is required to confirm the constancy of these 

 characters or otherwise. 



To A", trochilirostris (Lcht.), which is confined to Bahia in Eastern Brazil, 

 the Borba bird has not the least resemblance. X venezuelensis Chapm., of 

 Venezuela, Colombia, etc., is another very distinct form. I shall hope to discuss 

 the various races of the A. trochilirostris group on an early occasion. 



70. Deconychura longicauda (Pelz.). 



Deadrocincla longicauda Pelzeln, Znr Ornith. Bras. i. p. 60 (1867. — Borba, Rio Madeira ; Barra do 

 Rio Negro, and Marabitanaa). 



No. 1363. $ ad. in moult, Borba, 19. xi. 06. "Iris brown, feet bluish grey, 

 bill blackish grey." — Wing 110 ; tail 105 ; bill 27 mm. 



This bird agrees perfectly with one of Pelzeln's typical specimens in the 

 British Museum. As I have pointed out in the Bull. Brit. Orn. CI. xiv. 

 (Feb. 19114) p. 52, this species is congeneric with Dccowjchura ti/pica, erroneously 

 described by Cherrie as having only ten rectrices. 



Dr. Lorenz having kindly sent me the type and only known specimen of 



• I have not yet had an opportunity of examining D. paraensis L. Lorenz, from Para. 



t Two specimens in the Tring Museum. 



J The locality, Colombia, is no doubt erroneous.
