 yellow  on  the  tail, which  is so profuse on its latter two-thirds as almost  to ohscure  
 the  handing,  hut  like  all  the  other  speoimens  it  has  a  hlack  tip.  In  another  
 specimen  from Formosa, obtained  in March, the upper fur is slightly paler than m  
 the  dark-bellied  specimen,  and  the  under  surface  is  almost  concolorous with the  
 back,  hut  slightly washed  with ohestnut,  especially  over  the  hinder  half  of  the  
 belly,  while  it  is entirely  absent  on  the  chest  and on  the  anterior  two-thirds  of  
 the » « » I  ventral line, which is grizzled like the  sides.  Indeed, the  whole  of  the  
 belly is covered with annulated  hairs  like the upper  parts, with chestnut  hairs intermixed. 
   The tail  is  the  same  as  in  the  other  examples, but with little  yellow,  
 the hairs on the posterior third being rather broadly black tipped.  This form, then, is  
 in  the  grey-chested  phase.  Another  and  still  more  interesting  example from the  
 same island, but without recorded date, has a broad,  grizzled  line  down  the ventoal  
 surface,  the  chestnut, which  is  dark and rich,  being  restricted to two narrow lines  
 which do not extend anterior to the axilla, so that all the chest and throat are grizzled, 
 like the upper  surface.  Th e tail is broadly bl^k-tipped like the foregoing specimen. 
 The last  of  the  Formosan  examples  appears  to he identical with the last-descnbed  
 squirrel,  as  they  are exactly like each other, with this single remarkable exception,  
 that in  the  former  there  is  not  the  slightest  trace  of  rufous  on  the  under  parts,  
 which  are  grizzled  exactly like  the back.  I t  is a male, hut the date of  its capture  
 is not recorded.  These two  specimens  resemble in their coats the  squirrel  obtained  
 in  March,  with  the  rufous  only  faintly  showing.  The  existence  of  red  on the  
 belly  is  not  a  matter  of  age,  as  the  young  and  adults  are  both  rufous  on  that 
 area.  , .   I  H . 
 Two  squirrels  from  the  Island  of  Hainan,  clearly  referable  to  this  species,  
 differ  in  this  respect, that  the  specimen  shot  in  February  has,  as m  the  female  
 type, the  whole  of  the  under  parts  rich  chestnut,  extending  over  the  chest  and  
 throat •  whereas, in the other, the throat and chest and a line down the middle of the  
 belly are grizzled  without rufous, the  sides  of  the  belly  only  being  rich  chestnut.  
 The  tails  of  these  specimens  are  black-tipped, as  in the types, but broadly washed  
 over their ends with yellowish, as in one of the Formosan squirrels. 
 Blyth’s S. griaeopeetus was described from a living specimen, the habitat of winch  
 was  unknown,  but  it  agrees  with  those  squirrels  which  I   have  just  desoribed  
 from China, Formosa, and Hainan. 
 This  species  appears  to  be  confined  to  Western  China  and  to  the  Islands 
 of Formosa and Hainan.

 I  have collected about twenty-five specimens  of  this squirrel from various parts  
 of Burma, north of  the capital, and have found only  one  type of  variation, mst., the 
 orange-red  of  the  belly  occasionally  becoming  pure  yellowish-white,  sometimes  
 yellow.  In  all  the  individuals,  however,  that  I   have  examined,  the  ventral  
 aspect  is  distinguished by a grizzled mesial line, and the  end of  the tail is blackish,  
 broadly  tipped  with  orange-yellow.  A pale-bellied  individual  was  killed in  September, 
  but  I   have many  others  killed  in  the  same  locality on the same date and  
 of both  sexes, in which the belly has the characteristic orange-red of  this  species. 
 There  is  a  race  in  Assam which  agrees with 8. gordoni in the general colour  
 of  the  upper  fur,  but is  considerably  darker  on the under surface, and the mesial,  
 grizzled  line  is  occasionally  absent.  The  tail also closely approaches the character  
 of  8. gordoni,  but  it  wants  the  sub-apical black band, but its extremity is washed  
 with orange or yellow as in  this species.  The Assam form is larger and darker, and  
 has  sometimes been mistaken for 8.  hippurus and  8.  erythroeus,  Pallas, and  stands,  
 as  it  were, intermediate  between  the  Chinese  ventrilineated  8.  griseopectus  and  
 S. erythroeus ;  and  as it is doubtless quite as persistent as 8. gordoni and sufficiently  
 distinct  from  S.  erythroeus,  it  may  be  indicated  as  the Assam  var.  of  8.  gordoni,  
 and, for reference, stand as var. intermedia.  8. gordoni has the upper surface and a  
 narrow  line  from  between  the  fore  limbs  along  the  middle  of  the body grizzled  
 olive-brown or greyish with a variable rufous  tint ;  the annulations are  not  so  fine  
 as  in  S. erythroeus.  The chin and the sides  of the throat are paler-grizzled than on  
 the back and the lower part  of  the throat ;  the chest, belly, and inside of  the  limbs  
 are either  pale yellow  or rich orange-yellow, or  passing  into  pale  chestnut  in  the  
 Assam variety in which the belly is rarely lineated.  The ears  are  feebly  pencilled.  
 The  tail  has  the  same  proportions as in S.  erythroeus and 8. castaneoventris, but it  
 is more persistently and  uniformly concolorous with the body than in  these  species,  
 and is finely  ringed  with  black  and  yellow,  the  rings  being most distinct  on  the  
 latter fourth ;  the tip is  generally washed with oranger-yellow. 
 Length 9 inches, tail 7 inches. 
 S. gordoni, in its lineated belly, displays  a  closer affinity to  8.  castaneoventris,  
 which exhibits this character, than to S. erythroeus. 
 The skull of  this species, although considerably smaller than  that  of  8. erythroeus, 
  y et resembles it in form, but differs from it in its smaller teeth. 
 This squirrel ranges over Upper Burma to the north  of -the  capital, where it  is  
 very  common  about  villages.  Its  var.  intermedia  occurs  on  the  eastern  side  of  
 Assam, and is found also at Sadiya.
