MONOGRAPHS OF NORTH AMERICAN RODENTIA. 
1841.—Bonaparte, C.L. A new systematic arrangement of vertebrated animals. < Trans. Linn. 
1642.— 
Soc. London, xviii, 1841, pp. 247-304 (Classis i, Mammalia, pp. 247-258). 
[In sequence, this is essentially similar to the “ Synopsis vertebratorum systematis”, but a “‘ Conspectus fami- 
liarum et subfamiliarum”, with diagnoses of the groups, replaces the “Index”. As in the last, the groups 
Placentalia and Implacentalia are designated “ series’ and the Educabilia and Ineducabilia “subclasses”, and 
- the sequence of the subfamilies 15 and 16, 38 and 39, 54 and 55, are severally reversed. Compared with the first 
arrangement, the Hippopotamina, Rhinocerontina, and Tapirina are transfers from the Elephantidw to the 
Snide; anew subfamily (23) Dinotherina forming with (24) Elephantiva, the Elephantida, is interposed, whereby 
a total of 41 families and 76 subfamilies results. These modifications indicate the author’s emendations since 
1839, and therefore not the status of the article at the date of “ reading’’.]
