and body cream color to dull orange buff, with, more or less of the dark 

 bases of tbe hairs showing through, inner side of legs colored similarly 

 to under parts, but hairs scantier and colors duller; shoulder stripe 

 moderately pronounced, buffy in color. 



S'kull and teeth. — These do not differ materially from those of 

 Twpaia glis; the rostrum is if anything slightly relatively shorter in the 

 more northern animal. 



Measurements. — The usual measurements are: Head and body, 

 175-200 mm.; tail, 150-185; hind foot, 41-46 (less than ui T. glis); 

 zygomatic width, 24-26; width of brain case, 18.5-20; maxillary 

 tooth row, 17.5-19.5. 



Subspecies. — In addition to the mainland form, four msular forms 

 are recognized : 



Twpaia lacernata wilkinsoni, middle third of Malay Penmsula, 



page 52. 



Tupaia lacernata lacernata, islands of Lankawi and Terutau, 



page 53. 



Tupaia lacernata raviana, Butang Islands, page 54. 

 Tupaia lacernata obscura, Great Redang Island, page b5. 

 Tupaia lacernata longicauda, Perhentian Island, page 56. 



Remarlcs. — As a matter of practical con\enience the mainland sub- 

 species is first described, and comparison of the insular races made 

 with it. Tupaia lacernata is almost a perfect intermediate so far as 

 color is concerned between T. glis and T. helangeri. Tupaia hclangeri 

 is lighter in color and the contrast of its rather tawny rump with 

 the lighter anterior parts of the body more marked; its tail is not so 

 dark. The point of most perfect differentiation, however, is the 

 number of mammas. Twenty-four females of T. lacernata showing 

 developed mammce have the number 2-2=4, while 21 females of T. 

 helangeri have the number 3-3 =6.

Type-locality. — Ko-ldiau, Tarang (also spelled Trang and Trong), 

 Lower Siam. 



Type-specimen. — In the Selangor Museum, No. 1138/10, skin and 

 skull of adult male. Ko-ldiau, Tarang, January 12, 1910. I have 

 not seen this type. 



GeograpTiic distribution. — Tarang and extending northward toward 

 southern Tenasserim. See No. 5 on map on page 75. 



Diagnosis. — The brightest colored member of the species; rump more 

 ta^vny, larger than the insular forms except T. lacernata longicauda; 

 tail not so blackish as in the forms on the west coast islands, but 

 darker than those on the east coast islands. 



Color. — As described above under the species, brighter than any of 

 the subspecies, tail moderately blackish, rump rather tawny; shoulder
