DR. J. J. KAUP’S MONOGRAPH OF THE STRIGIDA. 247 
Dimens.—Head 67-68, bill from the gape 44, wing 268-275, tail 122, tarsus 59-60, 
middle toe 35 mm. long. 
Hab. Europe, and southern and northern parts of Africa and Asia. 
I can find no difference in specimens from the Cape of Good Hope. 
5. Srrix peruata, Licht. 
Strix furcata, Temm. Col. 432. 
pratincola, Bp. 
flammea, Wils. 50. 2. 
americana, Aud. 171. 
Diagn.—Tarsus 73-79, wing 300-315 mm. long. 
Descr.—Very similar to Strix flammea, but different in dimensions. In this species 
we find specimens in which the wings are nearly white. The end of the tail is more 
forked than in Strix flammea. 
Hab. Northern and southern parts of America. 
6. STRIxX DELICATULA, Gould. 
Birds of Austr. tom. 1. pl. 31. 
Strix javanica, De Wurmb. 
Diagn.—Tarsus 66-67, wing 255-280 mm. long. The webs of the feathers of the 
hinder ear-margins have along the shaft a black stripe, which is crossed at the top 
with a zigzag band or an arrow-like figure. 
Descr.—Very similar to the European Strix flammea, but the predominant ground- 
colour is ash-grey. 
Obs.—I cannot find any difference between the examples of this species from 
Australia and those from Java, and I feel quite sure that S. delicatula and S. javanica 
belong to one and the same species. 
7. StRIx SANTI-THOMA, Hartl. 
Diagn.—The feathers on the hinder ear-margins all rusty-yellow, with black shafts 
or black shaft-stripes ; near the gape and chin with dark-brown margins. Upper parts 
nearly black-grey, with white black-bounded spots. 
Descr.—Very nearly allied to Strix flammea, but the whole colour on the upper 
parts is darker, and the lower parts are more rufous and have larger black spots, 
one, or sometimes two on each feather. The face is darker, and the bands on the 
wings and tail are broader. 
Dimens.—Head 70, from the gape 37, tarsus 59-60, middle toe without the nail 31, 
with the nail 40 mm. long. 
I cannot give the dimensions of the wings and tail, because the only known speci- 
men in the Museum at Hamburg is a young bird.
