Though the three works last mentioned fairly come under the same category as the Planches enluminees and the Planches coloriees, no one of them can be properly deemed their rightful Des Murs.
The claim to that succession was made in 1845 by Des Murs for his Iconographie ornithologique, which, containing seventy-two plates by Prevot and Oudart l (the latter of whom had marvellously improved in his drawings since he worked with Vieillot), was completed in 1849.
Its basis is the classification of Cuvier, the modifications of which by Des Murs will seldom commend themselves to systematists whose opinion is generally deemed worth having.
Oologists have no reason to be thankful to Des Murs, notwithstanding his zeal in behalf of their study.
The attempt of Des Murs was praiseworthy, but in effect it has utterly failed, notwithstanding the encomiums passed upon it by friendly critics (Rev. de Zoologie, 1860, pp. 176-183,313-325,370-373).2 Until about this time systematists, almost without exception, may be said to have been wandering with no definite purpose.
