Tehuantepec. It is found on both sides of the central chain of the mountains of 
Guatemala and as high as 7000 feet on the slopes of the Volcan de Fuego. 
Mr. Richardson has sent us specimens from San Rafael del Norte in Northern 
Nicaragua, and Mr. Richmond found it on the Escondido river near the east coast ©. 
In Costa Rica Mr. Cherrie says it is tolerably common and resident near San José, 
-wwhere nesting probably begins in the latter part of April, as young birds are found by 
the 1st of June5. In the State of Panama it is a common bird, and we have received 
many specimens both from Arcé and M‘Leannan. 
C. virgata is a very variable species both as to the general colour of its plumage and 
to the intensity of its markings. Lawrence separated the Panama bird as Syrniwm 
lineatum *, considering it a smaller bird than C. virgata; the upper plumage not so 
dark, greyish, and the markings much smaller and more numerous, the under surface 
more rufous, with fewer and less distinct stripes. Birds with some or all of these 
characters can be found in almost any portion of the range of the species. 
The iris of a female shot in September 1873 on the Volcan de Fuego was dark 
brown, the food coleoptera.

Lawrence was the first to associate Sumichrast’s specimens of this Owl from 
Tehuantepec with Bonaparte’s description of Syrnium squamulatum 4, a name adopted 
from Lichtenstein. We have now several specimens from the same district, and we 
think they sufficiently differ from C. virgata to bear a distinct title; and, moreover, 
we trace the same bird northwards along the western States of Mexico as far as 
Mazatlan, whence Mr. Forrer sent us specimens which agree with the Tehuantepec 
birds. From this fact it follows that the birds of Grayson and Xantus from Western 
Mexico ascribed by Lawrence ° to Syrnium virgatum also belong to C. squamulata. 
It will be noticed that both these species of Owl are found on the Isthmus of
