98 SCIURUS VARIEGATUS. 



specimen of the same variety; lowerparts light reddish 

 white , feet white , neck and base of tail as in aureogaster. 

 Both they are from Mexico, the locality where the aureo- 

 gaster-YQxieij seems to predominate. 



It seems that the first upper premolar sometimes is de- 

 ciduous , as I find in six skulls two premolars , and in two 

 others a single one.

 ras; Nicaragua; Costa-Rica; Panama; Ecuador (if the lo- 

 cality of our N''. 36 is correct).
