Species of the Subfamily Diglossince. 205 



In tlie same year the second part of the synopsis of the 

 birds collected by D'Orbigny in South America, prepared by 

 himself and Lafresnaye, was published in the ' Magazin de 

 Zoologie/ D'Orbigny had obtained two species of this same 

 genus of birds in the Andes of Bolivia ; and the generic term 

 Serrirostrum (from the slight serrations on the edges of the 

 mandibles) was now proposed for them. In 1839 Lafresnaye, 

 while again describing Diglossa baritula under a different 

 name, proposed to change the generic term Serrirostrum into 

 Uncirostrum. Three years later Dr. Hartlaub"^ showed that 

 these various names were identical, and established the pri- 

 ority of Diglossa, which has since been generally accepted. 



In 1837, or thereabouts, as is stated to me in a kind com- 

 munication received from Dr. Cabanis, Lichtenstein was in- 

 tending to designate this genus " Campylops." But this term 

 was suppressed, and never actually published until 1851, 

 when it was referred to as a synonym of Diglossa in the 

 ' Museum Heineanum.^ 



In 1846 Lafresnaye gave a list of the eleven species of 

 Diglossa known to him in the 'Revue Zoologique" (p. 317 

 et seqq.). 



In 1864 the late Mr. Cassin gave an account of the species 

 of this genus represented in the Museum of the Academy of 

 Natural Sciences of Philadelphia t, and very needlessly pro- 

 posed subgeneric titles for the diff'erent divisions into which 

 he separated the group. 



About the beginning of 1840, when birds^ skins first began 

 to be received from Bogota, Mr. Fraser, in this country, and 

 the Baron de Lafresnaye, in France, described several new 

 species of Diglossa from this district at nearly the same date. 

 Since then a few others have been discovered in various parts 

 of the range of the Andes (one of which, D. plumbea, occurs 

 north of Panama), and a single species has been found in 

 the mountain-range of British Guiana. Altogether we are 

 now acquainted with fifteen well-marked species of this genus.
