includes it in his list as found at Cacoprieto on the Isthmus of Tehuantepec ; but 

 as the only specimen we have of Suraichrast's, labelled in his handwriting " Scops 

 maccalli" from this lowland locality is certainly one of S. cooperi, we conclude that 

 his bird was wrongly named. 



In Guatemala S. trichopsis has been found in several highland localities; but 

 one was shot in October 1862 at San Bernardo, in the valley of the Motagua river, 

 on the road from the city of Guatemala to Vera Paz, at au elevation of about 2000 

 feet above the sea. 



The front figure of the Plate represents a male from the Volcan de Fuego, Guate- 

 mala, and the back figure a young bird of the rufous phase from Cohan in Vera Paz.

We have a good series of specimens of this Owl from the lower portion of the Kio 

 Grande Valley, both from the Texan side of the river and from the Mexican State of 

 Nuevo Leon. They must, no doubt, be referred to Cassin's Scops maccalli, the types 

 of which came from the same district ^. How far to the westward of this region the 

 bird occurs we are not in a position to say, the Owls from Colorado Springs and from 

 Arizona being slightly different, and have been described as S. aiJceni and S. cinereus 

 respectively. The difference, however, between S. maccalli and 8. ailceni., or what we 

 take to be that bird, is exceedingly small, and consists chiefly in the central shaft- 

 stripes of the feathers of the latter being wider and more conspicuous ; and the absence 

 of any rufous phase in S. aikeiii, which, however, is rare in the former, may also be a 

 distinction. The supposed identity of S. maccalli with S. tricJiopsis has caused great 

 confusion in the synonymy of both birds, but we hope that in future this may be 

 avoided. We have, by correspondence with Mr. Ridgway, and by lending him several 

 of our specimens, come to full accord as to the status of S. trichopsis, as will be seen 

 under our account of that bird. 



Of the habits of S. maccalli hardly anything is recorded.
