 1 and 2. 



Type-locality. — Sumatra, probably Bencoolen. 



Type-specimen. — In British Museum, Reg. No. 95.3.21 .4, collected by 

 Sii' Stamford Raffles in Sumatra, probably at Bencoolen, a badly dam- 

 aged skull (no skin can be found), nearly everything posterior to 

 palate lacking, as well as right premaxilla, several of the maxillary 

 teeth lost; mandible perfect; not fuUy adult, the permanent upper 

 incisors just appearmg. 



Geographic distribution. — Sumatra, southern Borneo, in the low 

 country. See No. 5 on map on page 143. 



Diagnosis. — A relatively dark and dull member of the species, 

 especially in region of sides and shoulders, light area on either side of 

 dorsal stripe a mixture of ochraceous buff and blacldsh brown, neither 

 color m excess. 



Slcull and teeth. — Without definite subspecific characters. ("Plate 

 11, fig. 4.) 



Measurements. — ^Usual measurements of adults: Head and body, 

 200-220 mm.; tail, 160-180; hindfoot, 47-50; condylo-basal length, 

 54-56; zygomatic width, 25-27; width of braincase, 20-21; maxillary 

 toothrow, 19.5-21.5. For details of measurements see table, page 140. 



Remarks. — Two Sumatran specimens of Tana tana tana in the 

 United States National Museum differ slightly from the Bornean ones 

 in having the underparts ferruginous instead of orange rufous; but 

 both spechnens have been subjected to alcohol and one is still pre- 

 served in that fluid. The bullae of one of them, Cat. No. 174611, are 

 very small in comparison with the bullae of Bornean skulls, but the 

 latter show marked variation in the size of the bullae. The skull of 

 the second Sumatran specimen has bullae equaling in size the smaller 

 buUae of the Bornean specimens. Specimens from the Lampong 

 District, Sumatra, in the Philadelphia Academy of Natural Sciences, 

 do not show tangible differences from the Bornean specimens. 



Wagner's name speciosus w^as applied by him to a specimen in the 

 Erlangen Museum. His description applies more closely to the 

 southern Bornean form than to the brighter colored northern form. 

 Until the distmctness of the Sumatran longnosed treeshrew from the 

 lowland Bornean animal is established, speciosus must stand as a 

 synonym of tana, but in the event of their distmctness it will be avail- 

 able for the Bornean form. It is rather unfortunate that the exact 

 locality for Wagner's specimen is not known, but as most of the old
