''A specimen from the locality mentioned, while aj,M-ceinj,' in larger measurements 

 with the present form, is much browner above than those representing other locali- 

 ties mentioned, being exactly similar in coloration of the upjier parts to T. b. bairdi; 

 but Irolo is near the edge of the hitter's range, and the intermediate character of the 

 specimen may thus be accounted for. 



'' Four specimens.
