Total length, 8.00; wing, 3.30; tail, 4.20 ; graduation, 2.00 ; exposed por- 

 tion of Int primary, 1.27, of 2(1, 1.90, of longest (meaHored from exported baHe 

 of Idt primary), 2.45 ; length of bill from forehead, LOfi, from noHtril, .63; 

 along gupe, 1.20; turHUH, 1.32; middle toe and olaw, I.IU; olaw aloue, .37; 

 Liud toe and ulaw, .00; olaw aloue, .43. 



Tho genua Donacobius lias been variously placed by authors, by 

 some among the Thruslies, by others among tho WrenH. Tho notched 

 bill, the bristled rictus, and above all the deeply parted toes, with 

 the general coloration, appear however decidedly opposed to tho 

 latter view of its affinities ; and I have accordingly instM'ted it here. 

 It is a very strongly marked genus, and the only one of the family 

 without any representatives iu ><orthern or Middle America.* 



Having thus enumerated the species of T\irdidse from the region 

 embraced in the present work, which 1 have had the opportunity of 

 examining in the museum of tho Smithsonian Institution, or else- 

 where, I i)roceed to mention the remaining species which have been 

 given by other authors. Tho names used are generally those of Dr. 

 Sclatcr's Catalogue of American Birds, where tho precise syuouymy 

 will be found : —

' Most authors admit of but one species in the genus Donacobius, placing 

 the Bolivian D. allio-vittatim, of D'Orbigny, as a synonym of D. atricapillus. 

 Specimens in the Smithsonian collection, however, seem to indicate a decided 

 differonce in the much larger size of the Bolivian bird (length, 9.00 ; wing, 

 3.50 ; tail, 4.50— instead of 8.25 ; 3.20 ; 4.00). There is also a very con- 

 spicuous and distinct white stripe from the upper edge of the eye along the 

 side of the head to the nape. This stripe is only faintly indicated, generally 

 not at all in the atricapillus. The syuonomy will be as follows : —
