San Domiiujo. The Britisli Museum contains two specimens from 

 tliis island ; and, after examining them carefully, I fail to find any 

 pood reason why they should have hcen separated from the ordinary 

 North-American bird. The bars are narrower on the under surface 

 when compared with examples from other countries ; hut as I believe 

 these bars narrow with age, I cannot look upon them as evidencing 

 specitic distinctness. The under wing-coverts are also spotted with 

 brown near the outer edge ; but this is a character which seems to 

 obtain in certain specimens from South America, though at present 

 I have not seen any from North America which had any markings 

 on the under wing-coverts.

Uruguay. The iruscum contains a single bird from Maldonado, 

 collected by Mr. Darwin. It is a dark-coloured bird, and seems to 

 be identical with the true -S. cunicidaria of Chili,

Chili. I have examined a series of nine specimens from this 

 country, all of them collected by Mr. E. C. Reed. Placed side by 

 side with the North-American skins, they present a very much 

 darker aspect, and are decidedly larger. I have not as j'et seen 

 a light-coloured bird from Chili. The bars on the tail vary very 

 much in number, being five in two specimens, six in the next 

 two, and seven in the remaining five. This character, therefore, 

 cannot be regarded as of specific worth ; and, indeed, I think Mr, 

 llidgway pierfectly right in looking at the Chilian bird as merely a 

 large rei)resentative form of the North-American Burrowing-Owl. 

 I give the measurements of the nine Chilian specimens examined 

 by me.
