ZOOLOGICAL RECORD 
FOR 1881. 
MAMMALIA. 
BY 
W. A. Forbes, B.A., F.L.S., F.G-.S., Prosector to the 
Zoological Society. 
The year 1881 has, as far as Mammalia are concerned, perhaps shown 
rather a lull as compared with previous ones. This however has been 
caused, not by any appreciable diminution in the number of papers, but 
rather by the non-appearance of any fresh separate works of importance. 
The flood of new forms of extinct Mammalian life from North America 
shows as yet no sign of slacking, thanks chiefly to the unwearying 
labours and exertions of Cope (p. 3). Balfour (p. 2) has completed his 
masterly treatise on embryology, whilst Chapman (p. 2), Dobson (p. 4), 
Watson (p. 10), and others, have contributed numerous valuable papers on 
anatomical subjects. Of faunal publications, the Mammalia in Messrs. 
Salvin & Godman’s work on Central America (p. 5) have been practi- 
cally completed, and Peters & Doria (p. 7) have published a valuable 
account of the Mammalian fauna of the Papuan sub-region.
