NO. 1976. TREESHREW8: FAMILY TUPAIID^—LYON. 17 



The following natural divisions or areas of the Oriental, based upon 

 the genera and species found in the family Tupaiidse, may be recog- 

 nized. They are not of coordinate importance, nor are all of them 

 mutually exclusive. Those divided up by water seem to be suffi- 

 ciently distinct, however, to indicate that at some not very remote 

 period connections of some sort may have existed between them. 



Indian (excluding Ceylon), genus Anathana, and absence of other genera. 



Pliilippine (Mindanao only), genus Urogale, and absence of other genera. 



Indo-Chinese, the belangcri-chincnsis group of the genus Tupaia, absence of other 

 genera and species. (The distribution of Dendrogale is so irregular that I have disre- 

 garded it.) 



Nicobaran, the well-marked species Tupaia nicobarica, absence of other genera 

 and species. 



Palawan-Calamine, a fairly well-marked species group of the genus Tupaia, absence 

 of other species and genera. 



Bornean, a well-marked species group in each of the genera Dendrogale and Tana, 

 and by four well-marked species groups of the genus Tupaia. 



Belonging to this subdivision but without all the characteristics are Banka, Billiton, 

 and the Natuna and Karimata Islands. 



Sumatran-Peninsular, glis group of Tupaia and T. minor malaccana. 



Java-Borussan (apparently including high mountain region of southern Sumatra), 

 two species groups of Tupaia, absence of other genera and species. 



Sumatra-Bornean, genus Tana. 



Sumatra-Bomeo-Peninsular, genus Ptilocerus and the minor group of Tupaia. 



So few Tupaias are known from the Rhio-Linga Archipelago that 

 little can be said regarding its affinities. It has both Peninsular and 

 Bornean elements. The rather isolated Tambelan Islands have a 

 single species of genus Tana, evidently of Bornean origin, and the 

 isolated Anamba Islands, inhabited only by members of the splen- 

 didula group of Tupaia, also appear to be Bornean in their relations.
