dence, the Formosan house mouse is a form of Mus mesculus, and the field mouse 
is genetically highly differentiated from it,

Genera Rattus, Apodemus, and Mus from the Standpoint of Variation-Statisticsa" 
(with English resume): Mem Fec Sci Tainoka Imp Univ, I (2), pp 65-118, Jul 1944, 
Biostatistical studies were perforued on common Formosan rats and mice, namely, 
Rattus losea, Apodemus agrurius, Mus formosenus, and Mus musculus, From the 
standpoint of adult mean values in extreme dimensions (the lower limit of the 
adult size range is theoretically determined), the two species of Mus are close- 
£ ly related, and each genus has its own particularities in the relation of the 
bead and body length to the tail length; a sexual diversity is apparent in 
Rattus, quite lacxing in Mus; the ear iength is noticeably small in Apodenus,. 
The order of the amount of variability in their edult values is roughly the 
same in every species, being generally parallel to that of the amount of their 
equilibrium coefficients in the adult stage, except for the head and body length

Morphological descriptions are given of the Manchurian kangaroo rat, Dipus sagilta 
soweroyi Thomas (Dipodidae). Its hebitat and food habits are reported in detail, 
The hebits of Citelius dauricus ramosus Thomas {Scincidae), which occurs in great 
numbers in western Manchuria, a permanent pest zone, are reported, A detailed 
description of its hibernating habits is added, In the third report the author 
deals similarly with Meriones unguiculatus (Milne-Edwards) (Geribillinae-Muridae),

Different species of rats show marked preferences in habitats, some occupying 
human dwellings, others choosing cultivated fields, grassy plains, or swamp areas, 
Their habitat preferences are delineated, and their respecti-e effects on agri- 
culture are evaluated,
