On the maps showing the distribution of the various members of 

 the family Tupaiidse I have endeavored, as far as possible, to indi- 

 cate the localities mentioned in the text or the tables of measure- 

 ments and lists of specimens. In a few cases, however, I have been 

 unable to find some of the localities. Most of the maps are some- 

 what diagrammatic, but that on page 143 is carefully made and 

 shows virtually most of the localities whence specimens of treeshrews 

 have been obtained. In cases where a form is known, but from 

 a single locality the figures indicating the distribution have been 

 limited to the area around that point, where known, from two or 

 three rather separated localities, the distribution figures have been 

 extended to cover the intervening area, the assumption being that 

 the animal will be found there; when known from several scattered 

 areas, or a large land mass, or part of one, the distribution figures 

 have been liberally applied around the whole area. Future explora- 

 tions will undoubtedly show much wider ranges for many of the 

 forms shown on the maps. On the whole, I have been rather con- 

 servative in indicating the distributions, leaving it to the reader to 

 imagine a more extended range. Thus, we know that Ptilocercus is 

 found in the Deli-Langkat region, Sumatra, and it has been indicated 

 at that locality only, on the map. There can be but little doubt, 

 however, that it is found elsewhere in Sumatra, but owing to lack 

 of records I have not so indicated it, 



FOOD. 



Judging by the typically insectivorous nature of the cheek-teeth 

 in Tupaiidse, the diet of these animals must be largely insects. Many 

 observers say they naturally eat fruit as weU. Ptilocercus having 

 teeth sHghtly less insectivorous than the Tupaiinae, may perhaps 

 have a more varied diet. However, it is a very rare animal and 

 direct observations on living specimens still rarer. The only ones I
