RemarTcs. — Tupaia gracilis injiata is only shghtly differentiated 

 from T. g. gracilis. At the time it was originally described it was 

 compared with T. javanica and T. minor, and of course appeared to 

 be a very distmct form. It is weU established now that it has nothing 

 in common -with those two species. Two of the specimens. Cat. No. 

 124985, Billiton, and Cat. No. 124909, Banka, have the tails very 

 different m color from other spechnens, the usual buffy annulations 

 being replaced by russet or tawny ochraceous; it appears to be a 

 difference in pelage. 



Specimens examined. — Three, including the type, from Banka, and 

 three from Billiton.
