1735. Linnreus in the first edition of the 'Systema Naturjie' establishes 

 the order "Glires" to include the genera Hi/strix, Sciurus, Castor, Mus, 

 Lepus, Sorex. 



1748. Linniieus, 6th edition, also includes Didelphis. 



1758. Linnaeus mistakenly adds Rhinoceros, removes Sorex, Didelphis. 



1766. Linnpeus removes Rhinoceros, adds, "Noctilio americanus." 



1778. Pallas divides the Linnaean genera of rodents and carefully de- 

 scribes the anatomy. 



1779. Blumenbach puts the Rodents into the Order "Digitata" as a 

 division (A) coordinate with (B) the Carnivorous and (C) the edentate "Fissi- 

 peda." 



1780. Storr uses the term "Rosores" for the group. 

 1792. Vicq d'Azyr uses the term " Rodentia." 



1795. Geoff roy and Cuvier include the Kangaroo in the group. 



1800. Cuvier also includes the Aye-Aye, which was thought to connect 

 the order with the Primates. 



1811. Illiger calls the order "Prensiculantia" and divides it into eight 

 " familipe," removing the extraneous genera Daubentonia [Chiromys], Halma- 

 turus. 



1817. Cuvier excludes the Kangaroo but retains the Aye-Aye, divides 

 the order into "clavicules" and " non-clavicules." 



1816. De Blainville removes the Aye- Aye to the Primates (following 

 Illiger); he divides the order into "Grimpeurs" [Sciuromorphs], "Fouis- 

 siers" [Myomorphs], "Coureurs" [Lagomorphs], "Marcheurs" [Hystrico- 

 morphs]. 



1834. De Blainville more clearly anticipates the divisions of Brandt. 



1842. Waterhouse divides the order Rodentia into three suborders, 

 based on characters of the jugal, of the infraorbital foramen and of the lower 

 jaAV, namely "Murina," " Hystricina," "Leporina."
