304 Stone, Ornithological Works of J. J. Audubon. [July 



While Audubon was engaged in preparing the manuscript of the 

 first volume of the 'Biography' his wife "copied it all to send to 

 America, to secure the copyright there." 1 It was published under 

 the direction of Dr. Harlan in Philadelphia, and bears the same date 

 as the Edinburgh edition. A copy presented to the Philadelphia 

 Academy by Audubon is dated on the fly-leaf October, 1831. So 

 far as nomenclature is concerned the two editions are identical. 

 There are said to be copies from the Edinburgh types with a Phil- 

 adelphia imprint dated 1832 2 but these I have not seen. Of the 

 remaining volumes there seems to be but the one edition. 



Comparing the number of species recognized in the Folio with 

 those in the 'Biography,' we find that the Rough-winged Swallow 

 and Mourning Warbler are added in the body of the latter work 

 and sixteen others, mostly western species, in the supplementary 

 portion. Ten other species, seen but not characterized, are given 

 in a separate list at the end of Volume V, and in Volume IV a loon, 

 probably the large yellow-billed species known as Gavia adamsi, 

 is provisionally named Colymbus Richardsoni. 



As against these additions, five of the species of the Folio are 

 suppressed in the body of the text, and eleven recognized in the 

 early volumes of the latter are reduced to synonymy in the supple- 

 ment to Volume V. 3 We thus have 502 species recognized at this 

 period of which eleven, as stated above, were more or less hypothe-
