FOR 1883. 
MAMMALIA. 
BY 
Oldfield Thomas, F.Z.S., Natural History Museum. 
The year 1883 is, so far as Mammals are concerned, chiefly marked by the 
large number of palaeontological papers and books which have been pub- 
lished, among which those of Ameghino (p. 2), Cope (pp. 6 & 7), Filhol 
(p. 9), and Lydekker (p. 16) are the most prominent. Flower (p. 9) has pub- 
lished many important systematic papers, his Encyclopaedia article, “ Mam- 
malia , ” giving one of the best existing accounts of Mammalia generally, 
while his “ Arrangement of the Orders and Families of existing Mammalia” 
forms a distinct advance towards a permanent and rational classification of 
the group. Dobson (p. 8) has continued his Anatomical and Systematic 
Monograph of the Ivsectivora ; and other anatomical work has been done 
by Ercolani (p. 9), Lankester (p. 68), Poulton (p. 20), Spoof (p. 22), and 
others. Faunal papers, mostly of minor importance, have been put forth 
by Jentink (p. 14), Mojsisovics (p. 17), Yon Pelzeln (p. 19), Stearns (p. 23), 
and others. 36 new recent species have been described, as compared, 
with 46 in 1882 and 36 in 1881.
