Exclusive of a number of names proposed by Heude, which do not b 
appear entitled to take a place in the list, the following table shows the 
number of new generic and specific names recorded during 1888, a few 
of the latter being, however, those omitted from an earlier volume : —

In addition to these, three generic names have been proposed to 
replace preoccupied ones. 
The number of new generic and specific names proposed for fossil 
forms is much less than in the preceding year ; but there is an increase 
of fifteen in the number of new specific terms applied to existing 
Mammals. The most remarkable feature of the year, in this respect, is, 
however, the comparatively large number of new genera among living 
forms. Thus, of the seven new generic terms proposed during the year 
all but one indicate entirely new forms, of which the most interesting 
appear to be Pteralopex among the Chiroptera , Eupetaurus in the 
Sciuridce, and Deomys in the Muridce. A form which is, however, likely 
to prove of far more interest is the new Australian Mammal, to which a 
name has not as yet beon applied. The large number of new recent 
species is extensively made up of Soricidce and Muridce. 
The most startling feature among fossil Mammals is the discovery that 
the bones of the feet on which the presumed Edentate genus Macro- 
therium was founded are really referable to the Perissodactylate genus 
Chalicotkerium. Of considerable interest from a distributional point of 
view is the discovery of remains of Orycteropus in one of the islands of 
the Turkish Archipelago.
