on chin, and changing to whitish on middle of belly; sides and flanks washed 

 with buffy brown, and streaked with fuscous. 



Measurements of type. — Length (skin), 150 mm.; wing, 68.5; tail, 57.5; ex- 

 posed culmen, 10.5; tarsus, 20.5; middle toe without claw, 14.5. 



Remarks. — From the available material in the U. S. National Museum 

 selection has been made, for purposes of comparison, of four specimens of 

 P. m. modularis from France, Switzerland, and Norway, six specimens of 

 P. m. occidentalis from England, and three specimens (in addition to the 

 type) of P. m. mabbotti from the Pyrenees. As far as can be judged from 

 this material, the streaks on pileum and nape are much more distinct in 

 occidentalis than in modularis and mabbotti. The sides and flanks in Py- 

 renean specimens are conspicuously less rufescent than in British and Nor- 

 wegian specimens, and somewhat less so than in specimens of modularis 

 from France and Switzerland. In British specimens the tarsus and middle 

 toe average slightly longer, and the bill slightly stouter, than in specimens 

 of the two races from the Continent. 



In form of wing the Pyrenean bird appears somewhat intermediate be- 

 tween modularis and occidentalis. 1 In the type specimen the second pri- 

 mary is about 2.5 mm. longer than the seventh, while in a paratype from the 

 same locality (No. 256648, U. S. N. M.) the second and seventh primaries 

 are approximately equal. The average difference in length between these 

 primaries in the specimens of modularis is about 4 mm., and in the specimens 

 of occidentalis, less than 1 mm. 



Prunella modularis mabbotti appeared to be a rather common and char- 

 acteristic bird in late April in the belt of pine forest on the intermediate 

 mountain slopes near Saillagouse.
