includes it in his list as found at Cacoprieto on the Isthmus of Tehuantepec; but 
as the only specimen we have of Sumichrast’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 an 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 Coban in Vera Paz.

We have a good series of specimens of this Owl from the lower portion of the Rio 
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 ina position to say, the Owls from Colorado Springs and from 
Arizona being slightly different, and have been described as S. atkeni and S. cinereus 
respectively. The difference, however, between S. maccalli and S. aikeni, 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. aikeni, which, however, is rare in the former, may also be a 
distinction. The supposed identity of S. maccalli with S. trichopsis 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.
