All specimens from the lower Eio Grande Valley and North-eastern Mexico examined 

 by us have the tail of the ordinary hepatic type as seen in southern examples, but the 

 head and back are not nearly so rufous nor are they so grey as southern birds in that 

 phase. In the State of Vera Cruz dark-tailed birds begin to appear and are found 

 everywhere to the southward of that State. 



Dr. Sharpe separated the Mexican and Central American bird under the title of 

 G. ridgwayi, keeping the South-American bird and that of the island of Trinidad 

 distinct subspecies, calling them G. ferox (Vieill.) and G. phaloenoides (Daud.) 

 respectively. But admitting, as everyone must, a large amount of variation between 

 individuals of this Owl, we are not able, with the very large series of specimens before 

 us, to select any characters by which these races can be satisfactorily distinguished. The 

 range would appear to be quite unbroken from the Eio Grande of Texas to Paraguay. 



Daudin's name G . phalasnoides, bestowed upon the bird of the island of Trinidad in 

 1800, is the oldest 1.
