 e. Coloration deeper, more brownish above, more vinaceous below. (Interior

aZ[niaida] ruficauda Bonaparte, Consp. Gen. Av.. ii, 1857, 83 (Colombia; coll. Brit. 

 Mus.; ex Gray, manuscript). — Zenaida ruficauda Salvadori, Cat. Birds Brit. Mus.,

 (Bogota, Colombia; coll. G. N. La^vrence). 



I am not entirely satisfied that Z. bogotcnsis Lawrence is really the same as Z. rufi.- 

 caitda Bonaparte, the Un^e of which is in the Paris Musexim. It is possible that Z. 

 ruficauda is the same as the form which is here named Z. r. robinsoni, in which case the 

 form above characterized under the name Z. r. ruficauda would have to be named 

 Zenaida ruficauda bogotensis. I have not seen any specimens of this group having the 

 wing nearly as long as 162 mux. (6.30 inches), the measurement given by Salvadori for 

 the type and another specimen of Z. pcntheria Bonaparte.

 527 (Diamantina, lower Amazon. Brazil; coll. U. S. Nat. Mus.); Salvadori, Cat. Birds

 Birds Brit. Mus., xxi, 1893, 389, pait (Quonga, Takutu, and Aunai, British Guiana). 



Specimens from Quonga and Annai. British Guiana, have the distal portion of the 

 lateral rectrices deeply colored, as in Z. r. ruficauda and Z. r. vinaceorufa, but are 

 otherwise like typical Z. r. jessiex, including absence of bluish gray on occiput. An 

 adult male from Boa Vista, Rio San Francisco, Province of Pernambuco, eastern 

 Brazil, is considerably grayer above, has the occiput distinctly bluish gray, and may, 

 in reality, represent a different form.
