Megascops marmoratus, new species. MARBLED SCREECH 
OwL. 
Type, No. 155676, U. S. Nat. Museum, Dept. Agric. coll., 9, Catemaco, 
Vera Cruz, Mexico, May 4, 1894. Collected by E. W. Nelson and E. A. 
Goldman (Orig. No. 2002). 
Distribution.— The only known specimen of this bird was taken in the 
sparsely wooded country bordering the northern shore of Lake Catemaco, 
Vera Cruz, at an altitude of about 1200 feet. 
In size and general style of color this species is most closely 
related to Megascops guatemalensis, from which it may be distin- 
guished by its generally paler and grayer coloration, and by the 
finer dark shaft markings, both above and below. ‘The general 
color of the dorsal surface is light sepia brown, darkest on head 
and shoulders. The gray and dark brown, or dull fulvous, mot- 
tlings on both dorsal and ventral surfaces are much finer than in 
guatemalensis. ‘The legs to toes are thickly barred with white and 
reddish brown, the latter color being much paler than in the last 
named species. ‘Toes bare. 
From JZ. brasiliensis, as represented in the National Museum 
collection from various Central American localities, marmoratus 
may be distinguished readily by the absence of the dull yellowish, 
or fulvous, suffusion which pervades the plumage, just below the 
surface, in that species.
