Localities. — Nearly all the representatives of this species 
in the collec- 
tions of Princeton University and 
the American Museum, 
collected by 
Messrs. Hatcher, Peterson and Brown, were obtained on the Atlantic 
coast near Coy Inlet and from five to twenty miles south of that point; 
a few only were found at Killik Aike.
