XLVII. — On the Forms of Squirrel hitherto classed under 

 Sc. finlaysoni, Horsf. By R. C. WiiOUGHTON. 



This question was discussed by Dr. Anderson iu 1879 

 (Zool. Western Yunnan). He came to the conclusion that 

 tlie following forms, viz. finlaysoni, ferrugineus, keraudreniy 

 splendidus, cinnamomeus, siamensis, splendens, germani^ 

 hocourti, and leucogaster, were " only varieties of one and the 

 same species." 



It was again investigated by Bonhote in 1901 in dealing 

 with a collection of mammals from Siam (P. Z. S. p. 53). 

 The result was rather unsatisfactory, for while keeping all 

 the forms under the specific name finlaysoni, he recognized 

 four '^ types," but did not distinguish the forms which 

 ranked in each " type." 



Since then there have been considerable additions of 

 specimens of this group to the collection of the Natural 

 History Museum, and on laying out the whole and sorting 

 them both geographically and by pattern it seemed to me 

 possible to introduce some commencement of order in the 

 arrangement of the group. 



As a preliminary it may be noted that a study of the 

 literature shows that the following names disappear from the 

 list quoted above as synonyms, viz. Iceraudreni, Lpss.,= 

 ferruginexis, Cuv. j siamensis, Gray, and splendens. Gray, = 

 cinnainoineus, Temm. ; leucogaster, M.-Edw., and leuco~ 

 cephalusy Bonh., = /wco»r<«, M.-Edw.
