«■ Eight specimens. 



6 Three specimens. 



« A specimen from the locality mentioned, while agreeing 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 upper parts to T. b. bairdi; 

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

 specimen may thus be accounted for. 



I* Four specimens.
