v, p. 116. In the latter part of vol. vi, p. 92, Wilson used pennsylvanicus 

 for the Broad winged Hawk, but finding that he had already used the 

 name, he changed it to latissimus in the last edition of the volume. 



"BLUE H. F. C/ESIUS." This name was here proposed by Ord for a 

 presumably undescribed species. No reference or description accom- 

 panies it, but from the fact that he called it the Blue Hawk and as the 

 adult male of the Marsh Hawk is often known by that name, we 

 presume this was the bird intended. This view is strengthened by the 

 fact that Wilson did not figure or describe the adult male Marsh Hawk. 



In a manuscript foot note Mr. Ord says, "name preoccupied," and this 

 statement is correct, as Meyer proposed the name 'in 1810 (Tascheub. 

 Deutschl. Vogelk., i, p. 60) for a European Hawk, i. e. the Falco regulus 

 of Pallas, which latter name has priority.

 GENUS STRIX. 



S. bubo ~L,.=Bubo virginianus. (Gm.). 



S. mexicana=Asio mexicanus Gm. , a South American species. 



S. albifrons Shaw.=Young of Nyctala acadica (Gm.). 



S. otus L,.=Asio wilsonianus, an American species. 



S. ncevia Gm.=Megascops asio (I/.). 



S. flammea ~L,.=Strix pratincola Bp. At the time , Mr. Ord's work 

 appeared, the American Barn Owl was not distinguished from the 

 European species. 



S. passerina ~L,.=Nyctala acadica. 



S. hudsonia ~Wi\s.=Surnia ulula caparoch (Miill.). 



S. brachyotus Gm. Asio accipitrinus Pall. 



S. wapacuthu Gm. is based upon Pennant's "Wapacuthu Owl." The 

 description of this bird agrees very well with Bubo virginianus arcticus 

 (Sn.) except that it is included among the species without horns, so that 

 the name can hardly be used for this species, and must be disregarded. 



S. tolchiquatli and chichictli of Gmelin are unrecognizable. 

 S. funereal,, is Surnia ulula caparoch (Miill.).
