264 HasbrouCK, Distribution of North American Megascops. r^ 



M. hastatus probably extends from the type locality back into the 

 mountains for a considerable distance in every direction. 



Megascops vermiculatus Ridgxv. 



Costa Rica has been said to be by far the most productive of 

 bird life of all the Central American Republics, — a statement that 

 does not appear overdrawn on considering a fourth spepies of 

 Screech Owl in addition to the three already mentioned from that 

 country. Megascops vermiculatus was described from San Jos6 

 in 1SS7, the type and one other specimen, bearing simply "Costa 

 Rica" on the labels, being now in the U. S. National Museum. 

 Cherrie makes no mention of it in his list (Auk, IX, 327), 

 ami the species must be either exceedingly rare or overlooked in 

 his paper. The range has been given as central Costa Rica in 

 the vicinity of San Jos6. 



Megascops aspersus Brcwst. Spotted Screech Owl. 



The only known specimen of this bird is in the collection of 

 William Brewster, who described the species in 1SS7 from El 

 Carmen, Chihuahua, Mexico. 



Megascops vinaceus Brewst. Chihuahua Screech Owl. 



Like the preceding species, nothing further is known of the 

 Chihuahua Screech Owl beyond the type specimen taken at 

 Durasno, Chihuahua, Mexico, and described in iSSS.
