 157. Trogou variegatiis variegatus Spix. 



Trogon varifynttis Spix, Av. Bras. i. p. 49. tab. xxxviii a. (1824. — " ia Bra-silia" — type examined). 



Nos. 2229, 2284. c? ? ad., Rio Aragaaya, June aud July l',Mi6.— Witig 127, 

 125 ; tail 134, 130; bill 19, 17 mm. 



Agreeing iu size and coloration with specimens from Rio de Janeiro and 

 Bahia. 



In Eastern Bolivia and N.W. Argentina T. v. variegatus is replaced by a larger 

 race with shorter white tips to the onter rectrices. This is T. variegatus bekni 

 Gonld.* Cf. my revision of Spix' types, p. .597. 



Whether T. bolivianus Grant is different from T. v. behni appears to me to be 

 extremely doubtful. Moreover, it is quite inconceivable why the author should 

 have chosen the term bolivianus for a bird which, according to his specimens, is only 

 found in Pern and Eastern Ecuador. 



lo8. Trogon surrucura Vieill. 



Trogon surrucura Vieillot, Nnnv. Did. viii. p. 321 (1817. — ex Azara No. 270 : Paraguay). 



Nos. 2012, 2023. c?c? (in moult), Goyaz, April 1906. 



In coloration, these specimens are practically identical with an adult male from 

 Sapucay, Paraguay, but seem to be somewhat smaller. Both are, however, 

 moulting. 



The distribution of this species is rather curious. Natterer obtained it 

 near Mattodentro and Ypanema in S. Panlo. The Tring Museum received 

 specimens from Victoria, in the same state, secured by Mr. A. Hempel ; from 

 Ro?a Nova, Serra do Mar, Parana, and Rio Jordao, Minas Geraes (A. Robert) ; and 

 from S. Javier, Misiones, Argentine (White). 



T. auratitius Spi.x, which differs only by having the under-parts orange-yellow 

 (instead of blood-red) we have from Bahia, and from Piqnete, S. Panlo (Robert), 

 while an adult male from Novo Fribnrgo, Rio, is intermediate between T. surrucura 

 and T. aurantius. More information is required about these two forms before 

 their distinctness can be considered as established. 



1.59. Anodorhynchvis hyacinthinus (Lath.). 



PsMacus hyacinthinus Latham, Iml. (ini. i. p. 84 (1790. — hab. ign., we fix Brazil as the typical 



habitat).

Nos. 2231, 2232. ? ? ad., Rio Araguaya, June 1906. 



The Aragna3-a seems to be one of the principal hunting-grounds of this beautiful 

 bird, for Natterer and Comte de Castelnau also met with it on the banks of that 

 river. It is still very rare in collections. 



The Tring Museum possesses, in addition to the two fine e.\amplcs sent by 

 Mons. Baer, a couple obtained on the Rio Parnahyba, State of Piauhy, N.E. 

 Brazil.
