TREESHREW8: FAMILY TUPAIID^—LYON. 



151 



Measurements. — Type: Head and body (dried skin), 260 mm.; tail 

 (dried sldn), 160; hindfoot, 50; zygomatic width, 28; width of brain 

 case, 21; maxillary tooth row 22. 



Remarks. — Tana paitana appears to be a very distinct species, 

 nearly as much so as T. chrysura, the surrounding of the shoulder 

 stripe by the grayish of the anterior back being a feature unknown in 

 other species; the distinct ferruginous instead of blackish color of 

 the lower back is also distinctive. It appears to be more nearly 

 related to Tana chrysura than to T. tana as far as its general colora- 

 tion is concerned, excepting of course the tail. T. chrysura has rather 

 large grayish areas on the anterior back, but they do not embrace the 

 shoulder stripe. The specimen from Banguey Island is provisionally 

 referred to T. paitana. The specimen is immature, and it does not 

 appear advisable to found a new name on its smaller size and m®re 

 blackish lower back. 



Specimens examined. — Two, the type, and one from Banguey 

 Island, off northeastern Borneo. 



Measurements of Tana chrysura and paitana.
