M. a. cinera'ceus. (Lat. cinerexs, ashy.) Mexican Screech Owl. Described by Ridg- 

 way as having the bars of the lower surface fine, closer than in asio, and much more uniformly 

 distributed ; general aspect paler than in asio, with much finer vermiculations. Later described 

 by Ridgway as "nearly pure ashy-gray above, the usually broad black mesial streaks in con- 

 spicuous contrast ; blackish bars on lower parts very numerous, narrow ; black border to face 

 without admixture of brown, and black spots on breast usually without distinct brown exterior 

 suffusion; length about 6.50-8.00; wing 6.10-7.00 ; tail 3.10-3.70." Lower California, Ari-

M. trichop'sis. (Gr. 6pi$, thrix, gen. rpixos, trichos, hair; o\//'tj, opsis, aspect.) Wagler's 

 Owl. Spotted Screech Owl of Brewster. Distinct from any of the foregoing to wliich 

 the name has been misapplied. Adult 9^ "Sides of head conspicuously fringed with black 

 bristles, longest on auriculars and superciliary rufifs ; tarsi densely feathered on all sides to the 

 toes, the latter sparsely feathered above ; throat and sides of neck pale rusty chestnut ; re- 

 mainder of jdumage coaisely spotted and barred almost everywhere with dull black " (Brewster).

 1.17; middle toe 0-67 ; cuhneu from nostril 0.40; depth of bill 41; longest feathers of ear- 

 tufts 1.00; Huachuca specimens smaller; wing about 5.25, etc. The fringing filaments of the 

 face give this species an unmistakable aspect and the name iriclwpsis: it was unknown to U. S. 

 ornithologists till described as aspersus by Brew.stek. S. trichopsis Wagler, Isis, 1832,
