 Duclos says, " Habite le Mexique pour sa plus grande 

 taille, la Californie pour sa plus petite, et la Nouvelle HoUande 

 pour la variele blanche." The variety (f. 19. 20.) is evidently 

 a distinct species. — Mr. Reeve's punctuation seems to imply 

 that Real Llejos is in Mexico, but since Real Llejos is not in 

 Mexico, the latter must be another habitat on the authority of 

 Mr. Cuming, unless Mr. R. has fallen into a geographical 

 error.
