44 Mr. C. Chubb on Birds from [ibis, 



Argentinas and one from Santa Catalina that are smaller 

 than the others. These represent Columbina aurisquamafa 

 Ley bold, wiiich can be separated, by their smaller size, paler 

 coloration above, and purple-grey below, under the fol- 

 lowing name : — 



Leptophaps ay mar a aurisquamata. 



Culumbina aurisquamata Leybold, Leopoldina, Heft viii. 

 1873, No. 7, p- 53 ; Pampas Argentinas. 



Metriopelia aymara Salvad. Cat. B. Brit. Mns. xxi. 1893, 

 p. 499 (part, specimens o-r). 



The four specimens in the British Museum from Pampas 

 Argentinas are smaller and paler in coloration than others 

 from Bolivia, and as Leybold has already named the bird 

 from there, it may be well to regard it as a subspecies of 

 L. aymara aymara. 



Leptoptila verreanxi verreauxi. 



Leptoptila rerreami Bonnp. Consp. Av. ii. 185i, p. 73: 

 New Granada. 



The series in the British Museum of this l)ird, which has 

 hitherto been placed under L. verreauxi Bonap., appears to 

 me to contain several subspecific forms and can be easily 

 divided into geographical subspecies. 



The material at my disposal shows that the Colombian 

 and western Venezuelan birds are the same. I cannot, 

 however, vouch for the eastern Venezuelan ones, as there 

 are none in the National Collection. 



Leptoptila verreauxi riottei. 



Leptoptila riottei Lawr. Ann. Lye. New York, ix. 1869, 

 p. 138 : Navarro, Costa Rica. 



The birds from Costa Rica and Panama in the British 

 Museum are, as a rule, larger in size, and as Lawrence 

 has already introduced a name, it may as well be used for 

 individuals from these localities. It is quite possible, of 

 course, that with a larger series other characters may be 

 discovered.
