 Page 55, Bangs and Penard (Bull. Mus. Comp. Zool., LXII, No. 2, 

 1918, p. 47), consider Ara severa (Linn.) to be represented by two 

 subspecies, the birds from the Guianas and Amazonian region 

 being separable on account of their shorter wings and more 

 naked cheeks. Birds from Encontrados, Venezuela approach 

 the Guiana form having wing measurements of 222 to 236. If 

 these characters prove sufficiently constant to be worthy of 

 subspecific recognition, the forms will stand as follows: 

 Ara severa severa (Linnaeus) . Brazilian Macaw. 



Psittacus severus Linnaeus, Syst. Nat., ed. 10, I, 1758, p. 97 



("Indies" i.e., Amazon River).* 

 Range: Guianas and Amazon Valley. 

 *Ara severa castaneijrons (Lai resnaye) . Lafresnaye's Macaw. 



Ara castaneijrons Lafresnaye, Rev. Zool., 1847, P- 66 (Bolivia). 

 Range: Panama and Colombia to Bolivia. 

 i: Colombia (Rio Cauca). 

 Page 83, 9th line from bottom, to the range of Amazona amazonica 

 tobagensis Cory add Trinidad (c/.. Bangs and Penard, Bull. Mus. 

 Comp. Zool., LXII, No. 2, 1918, p. 48). 

 Page 141, after Chceiura brachyura (Jar dine) add: 



ChcBtura brachyura prcevelox^ Bangs and Penard. St. Vincent Short- 

 tailed Swift. 

 ChcBtura brachyura prosvelox Bangs and Penard, Bull. Mus. 



Comp. Zool., LXII, No. 2, 1918, p. 60. 

 Range: St. Vincent, West Indies. 

 Page 171, PhcBochroa cuvierii notia Todd becomes a synonym of Phceo- 

 chroa cuvierii berlepschi Hellmayr and Seilern, as they are now 

 considered to be inseparable. 

 Page 172, after Thaumasius taczanowskii (Sclater) add: 



Thaumasius taczanowskii Jr actus Bangs and Noble. Huancabamba 

 Humming Bird. 



•Type locality substituted by Hellmayr (Abh. K. Bayer, Akad. Wiss., 1906, 

 p. 578). 



^ ChcBtura brachyura prcevelox Bangs and Penard: Similar to C. b. brachyura 

 (Jardine) from Trinidad and Tobago, Guiana, etc., etc., but differs in having the 

 underparts paler and browner and less blackish; rump and upper tail coverts dis- 

 tinctly paler, more ashy, the upper tail coverts much lighter and tipped with whitish. 

 The type locality "St. Vincent" must, therefore, be excluded from the range of 

 typical C. b. brachyura.
