Family STRIGIDJE. 



Genus Strix Linnaeus. 

 Strix LINN^US, Syst. Nat, ed. x, i, p. 92, 1758. 



Range. Almost cosmopolitan. Galapagos Archipelago. 



46. STRIX PUNCTATISSIMA Gray. 



Strix punctatissima GRAY, Zool. Voy. Beagle, in, Birds, p. 34, 1841 (James 

 Island). RIDGWAY, Proc. U. S. Nat. Mus., xix, p. 583, 1896. ROTHS- 

 CHILD AND HARTERT, Novit. Zool., vi, p. 175, 1899. 



Range. James, Indefatigable, South Seymour, Abingdon and 

 Albemarle. (Records of this species from the mainland are doubtful.) 



Two immature specimens are in the collection. They are only 

 slightly fulvous below, being chiefly grayish, spotted with dark 

 brownish. The wing in each is less than two hundred and thirty 

 millimeters. One of the specimens is from near Tagus Cove, Albe- 

 marle, where it was secured in a cavity on the side of a steep walled 

 canyon ; the other was taken from a cavity between some rocks on 

 Seymour Island. 



Several old nesting burrows were seen on canyon sides near Tagus 

 Cove, Albemarle, and in one an old unhatched egg was found. This 

 egg is whitish and in shape is slightly more spherical than the eggs of 

 Strix pratincola Bonap. It measures 41 X 31. The entrances to the 

 burrows were strewn with the skulls and other remains of rats (J/#.y), 

 the rodents apparently forming the greater part of the food of the owls. 



Family BUBONID^E. 

 Genus Asio Brisson. 

 Asio BRISSON, Ornithologist, i, p. 28, 1760. 



Range. Absent in most of the Australian region, otherwise cos-
