brown. I cannot find a difference in specimens from tlie Cape of 
Good Hope, Europe, Africa. 
6. Str. perlata, Licht. ; furcata, Temm. PL Col. 432. — Tarsus 
73-79; wing 300-315 mm. long. — In this species we see specimens 
whose wings are nearly white ; the end of the tail is more or less 
furcated than that of Str. flammed. Northern and South part of 
America. 
7. Str. delicatula , Gould, B. of Austr. t. i. — Tarsus 67-67 ; wing 
255-280 mm. long ; the webs of the hind ear margin have a black 
stripe along the shaft, which is closed on the top with a zigzag 
crossband, or an arrow-like figure. Very near to the European, 
but the predominant colour is grey. I cannot find any difference 
between the examples of this species from Australia and those from 
Java; and I feel quite sure that delicatula and javanica belong to 
one and the same species. 
8. Str. Candida , Tick. Journ. A. S. R. ii. p. 572 (1833) ; longi- 
membris, Jerd. Madr. J. Lit. and Sc. p. 86 (1839); capensis , 
A. Smith 111. S. Afr. Zool. pi. 45. — Tarsus 85 mm. long; upper 
parts more or less uniform brown or blackish. Cape of Good 
Hope and Madras. 
In this subgenus I have mixed the types of two small subgenera. 
I ossibly the species with very long tarsi may form a new subgenus, 
which we can call in future Scelostrix. 
d. Subgenus Dactylostrix. — With shorter wings and shorter 
"ing-ends, which do not overreach the end of the tail ; second quill 
t lie longest ; third as long as the second. They have not the light 
aei ial body of the second subgenus Stria j, but they have a stronger 
1 1, powerful toes, and stronger shafts to the quills; the toes yellow 
'vith fine scales and bristle-feathers. They are large Owls, and 
Prey upon animals larger than mice. 
-L Str. castanops , Gould, B. of Aust. tom. i. — Middle toe 57-58 
mm. long. Australia, Van Diemen’s Land. 
10. Str. personata, Vig. p roC . Zool. Soc. p. 60 (1831) ; Str. 
G° U R B. of Aust. tom. i. — wings 312; tarsus 61-33; 
middle toe 42-46 mm. long. 
c. Subgenus Megastrix. — With short wings and short and ob-
