In the preceding list, I Lave not given, as entitled to consideration on 

 account of priority, any names which are to be considered doubtful according 

 to my present knowledge. At this particular time, I may be allowed to say, 

 however, that I have various other authors in view for introduction to orni- 

 thological society, without being as yet quite sure what figure they will make, 

 nor what established relations they may disturb. 



In the " Deliche Naturae Selectae," Prof. Muller is associated with Georg 

 Wolfgang Knorr, and the work is sometimes quoted as that of the latter 

 named author. It is mainly a series of Illustrations in the various classes of 

 Zoology ; and many of them are excellent colored plates, especially those of 

 Crustacea, Insects and Minerals. This work only relates to Ornithology in 

 giviug figures of the following species :
