312 Mr. O. Salvin's Visit to the 



Veragua and Chiriqui (Arce); Costa Rica (Carmiol)', Vera 

 Paz, Guatemala {Salvin). 



Zenaidura graysont, Lawr. Ann. Lye. N. Y. x. p. 17 (1871), 

 is a distinet species, with strongly defined scapular marks 

 almost as in Zenaida galapagoensis. It is, however, much 

 larger than that species. 



Zenaidura yucatanensis, Lawr. Ann. Lye. N. Y. is. p. 207 

 (1869). 



Appears to be also a good species, having the colours of the 

 Antillean Zenaida amabilis, but the tail with fourteen rec- 

 trices as in Zenaidura carolinensis. 



Leptoptila riottii, Lawr. Ann. Lye. N. Y. ix. p. 137. 



Notwithstanding its having a shghtly larger beak, the type 

 specimen of this species is, I am convinced, to be referred to 

 L. verreauxi, an abundant species in the northern parts of 

 South America, and in Central America as far north as Costa 

 Rica. 



Leptoptila bonapartii, Lawr. Ann. Lye. N. Y. x. p. 15. 



I could not see that this bird really differs from our L. 

 plumbeiceps. Mr. Lawrence's skin of the latter bird is some- 

 what darkened with grease, and has thus misled him as 

 to the true coloration of the species. The name, L. albifrons, 

 attached to Mr. Lawrence's type of L. bonapartii is no doubt 

 wrong ; but Prince Bonaparte could never have seen the skin, 

 as the date on the label, 1859, shows that it was obtained 

 at least two years after his death. 



Tinamus frantzii, Lawr. Ann. Lye. N. Y. ix. p. 140 (1868). 



I have lately acquired a skin of this bird from Costa Rica, 

 and have also seen the type of the description. The species 

 is undoubtedly the same as Tinamus bonapartii, G. R. Gray, 

 Nothocercus bonapartii of oiu' '^ Nomcnclator,' p. 152. 



Whilst in the United States I had the pleasure of seeing, 

 for the first time, the new work on the birds of North Ame- 

 rica, by Prof. Baird, Dr. Brewer, and Mr. Ridgway; and 

 during my stay in Washington I took the opportunity of look- 

 ing into several points discussed in its pages upon which I
