188 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.45. 



Diagnosis. — A member of the splendidula group, characterized by 

 lighter neck and shoulders, and by a dark stripe extending from nape 

 onto lower back much as in the case of Tana tana; tail with a distinct 

 grizzle, resembling that of Twpaia carimatse; mammae, 2-3 = 5 ? 



Color. — Based on two individuals from the Kutei River region. 

 Upper parts and sides of neck and body, upper side of tail, and outer 

 side of legs, a fine grizzled mixture of chestnut or dark cimiamon 

 rufous and blackish, the reddish color slightly in excess except along 

 middle line of neck and body where the blackish color forms a stripe 

 about 2 millimeters wide anteriorly and nearly 20 millimeters wide 

 over lower back. Anteriorly the reddish color inclines toward 

 ochraceous. Under parts and inner side of legs varying from buffy 

 to ochraceous with darker bases of the hairs showing through. Under- 

 side of tail similar to upper, but lighter color more tawny or tawny 

 ochraceous and more conspicuous on either side of the middle line 

 than is the brownish black color. Shoulder stripe well marked. 



Slivll and teetli. — Essentially as in Twpaia splendidula, but brain 

 case slightly wider, approaching that of T. picta. 



Measurements. — Female with moderately worn teeth and female 

 with last molars appearing: Head and body 166, 169 mm.; tail, 143, 

 157 ; hmd foot, 40, 41 ; condylobasal length, 46, 43.5 ; zygomatic width, 

 26, 23; width of braincase, 19, 19; maxillary toothrow, 18, 18. 



Specimens examined. — Two, both from Loa Bamban, near Samar- 

 inda, Kutei River, eastern Borneo. 



Remarlcs. — With the exception of the dark dorsal stripe, this species 

 closely resembles Tupaia carimatse (page 98) in color, but the skull 

 is larger and wider. The presence of the dorsal stripe is somewhat 

 suggestive of T. picta, but the stripe is not so pronounced or narrow, 

 and the whole animal is much duller in color and apparently closely 

 related to T. spendidula. I have not examined the type of T. milUeri, 

 and the above identification is made with some reservation.
