MAMMALS FROM BURMA 931 
ground-colour, represents exactly the development for ornamental 
and no doubt sexual purposes that has taken place in S. py- 
gerythrus var. phayrei (1). 
Of course as a local and definable race this form ought to 
have a name, but when further specimens are obtained from 
intermediate localities and at different seasons of the year, it 
seems probable that that name will have to be of subspecific 
rather than of specific character. 
It should be mentioned however that the only female of this 
series in which the mammae are visible has three pairs, S. gor- 
dont and S. atrodorsalis having only twe, but the number of 
the mammae does not appear in the squirrels to be nearly so 
constant as it is among the Muridae. The numbers of mammae 
noted under the next heading are an example of their varia- 
bility in the present group.

is. ferrugineus, F. Cuv. auctorum. 
9 specimens from Bhamò, July 1885. 
1 from Rangoon, March 1886. 
1 Tounghoo. 
1 Palon (Pegu). 
The name here used for this well-known squirrel, besides 
having a priority of five years, as was shown by D." Ander- 
son (*), appears to be more convenient than “S. ferrugineus ” 
for a species which has such innumerable colour variations , 
many of which are by no means “ ferrugineus.”’ 
Of the only two specimens of this series in which the mam- 
mae are visible, one has four, as in S. atrodorsalis, and the 
other has eight, a number altogether exceptional, and probably 
abnormal. ) 
The specimens from Bhamo are mostly of the brilliant red 
colour characteristic of the form described by Gray as S. splen- 
(1) See P. Z. S. 1886, p. 69.
