It seems extremely doubtful whether the descriptiou of Si/lma cucicllata really 

 refers to the present species, no mention being made of the cinereous colour of the 

 crown. 



7. Basileuterus flaveolus (Baird). 



Mi/iothli/pia flaveoluK Baird, Review Amer. Birds p. 26'i note (May 18155. — Paraguay, Capt. Page 

 coll.) ; Pelzeln, Ziir Ornlth. Bras. ii. 1868. p. 72 (Goiaz). 



No. 2285. ? ad., Rio Araguaya, 550 metr., July 1906.— Wing 62; tail 62; bill 

 12i mm. 



This bird agrees perfectly with several Bahia skins. An adult male from 

 Maranhao, N.E. Brazil (taken September 9, 1905, by F. Schwanda), iu the Museum 

 of H.R.H. the Prince of Bulgaria at Sophia, and au adult bird (not sexed) obtained 

 by Mocquerys on Mount Bncarito, state of Tocuyo, Venezuela, in the Tring 

 collection, are not different either. Tlie latter specimen extends the range of 

 the species, which was hitherto only known from Paraguay and the interior of 

 Brazil, far to the north. 



I may also mention in this connection that the so-called female of Muscicapa 

 bivittata Lafr. & D'Orb.,* on examination, proves to be an example of the present 

 species. It is a skin in good condition, labelled: "No. 150. D'Orbigay, 1834, 

 Chiquitos. D. No. 352," and agrees in every way with several specimens from 

 Bahia collections. 



The range of B. flaveolus thus far known is as follows : 



Paraguay (Capt. Page — type No. 16,33-t, ?, June 1859, in coll. U.S. National 

 Museum, Washington) ; Brazil : Bahia (many skins in Mus. H. v. Berlepsch, Tring, 

 etc.); Goiaz (Natterer), Rio Araguaya (Baer), Villa Bella de Mattogrosso (Natterer); 

 Rio das Pedras and Porto do Rio Parantl, North S. Paulo (Natterer) ; (Jhapada, 

 Mattogrosso (Smith), Urucum (Borelli); Maranhao (Schwanda); East Bolivia: 

 Chiquitos (D'Orbigny) ; Venezuela : Mt. Bncarito, state of Tocuyo (Mocquerys).

No. 2174., av. imm., Rio Thesonras, 600 metr.. May 1906.— Wing 60^ ; tail 

 53; bill 11 mm. 



This bird differs from others from S. Paulo (Victoria) and Minas Geraes (Rio 

 Jordao) in having the breast and abdomen slightly flammnlated with pale yellowish, 

 and the sides more washed with brownish yellow. Both these divergencies are 

 apparently signs of immaturity. Cf Allen, Bull. Amer. Mus. N. Y. iii. 1891, p. 344.
