Length of skin, 22 inches; wing from flexure, 15 inches;

 nail, 3£ inches ; outer, 21 inches ; inner, 2i inches ; tail, 53 

 inches. 



Obtained near the coast of California, in the latitude of Mon-

From the cabinet of Nicolas Pike, Esq. 



Some writers have considered this species North American,
