The classification of Prince Charles Lucien Bonaparte exhibits the 

 following interesting features: (1) The adoption of the Linnsean names for 

 the Cuvierian orders; (2) The influence of de Blainville's classification 

 of 1816, in the grouping together of the Marsupials and Monotremes; 

 (3) The apparent modification and development of de Blainville's idea 

 of classifying the mammals according to the "variations of the encephalic 

 nervous system," namely, the use of brain characters as subclass criteria. 

 The mammals are divided into two series: (1) "Educabilia" (or those 

 with a "bi- or tri-lobed cerebrum") and (2) "Ineducabilia" (or those with 

 a "single lobed cerebrum"). Dr. Gill informs the writer that this idea was 

 suggested to Bonaparte by a friend. At any rate it grouped together animals 

 in similar stages of brain evolution, but otherwise not closely related. 



Bonaparte's twofold division of the Placentals is chiefly noteworthy be- 

 cause it was adopted in the subsequent classifications of Gill (1872) and 

 Cope (1880), and may have suggested to Owen his classification of 1868, 

 which was also based on brain characters.

1 In his classification of 1831 (' Saggio di una distribuzione metodica degli Animali Verte- 

 brati,' Giorn. Arcad. 49, pp. 3-77) Bonaparte adopted the Linnaean orders but did not introduce 

 the distinctive features wliicli characterized his classification of 1837.
