2 Mamm. 
II. MAMMALIA. 
INTRODUCTION. 
By far the most important event — an event besides which all others in this 
branch of zoology fade into insignificance — which the Recorder has to 
chronicle is the description by Andrews of the evolution and phylogeny 
of the Proboscidea. Next in importance is the evidence brought together 
by the same palaeontologist in favour of affinity between Proboscidea and 
Sirenia. Perhaps the third place in relative importance may be assigned, 
if the inference be true, to Wortman’s description of an American Eocene 
Lemuroid believed to be allied to the Malagasy Aye-aye. A highly 
important piece of work is Bensley’s Memoir on the “ radiation ” and 
affinities of the Australasian Marsupials. 
Special attention may also be directed to the papers by Dublin, Osburn, 
and Shimer on the adaptation of Mammals to particular modes of life. In 
this connection reference may be made to the observations of Racovitza 
in regard to the sleep of whales, and the depths to which those animals 
descend. During the year the subject of coloration has been discussed by 
Barrett- Hamilton, Pocook, and the Recorder. Elliot-Smith has con- 
tributed several important memoirs on brain-structure ; — a subject which 
has also engaged the attention of other observers. 
Reverting to palaeontology, the description by Dawkins of remains of 
Pliocene age in a British cave is an event of the first importance. Two 
other palaeontological memoirs — namely the one by Schlosser on the 
Tertiary Mammals of China, and that by Scott on the Loricate Eden- 
tates of Patagonia, likewise claim special notice. 
Systematic work has progressed rapidly during the year, Transatlantic 
zoologists continuing work on the fauna of the Old World. Amopg notable 
novelties, reference may be made to the description by Matsohie of a 
gorilla from East Central Africa, and to Thomas’s identification of a new 
species of Rhinopithecus.
