Type-locality. — East Perlientian Island, off Tringanu, east coast of 

 Malay Peiiiiisula. 



Type-S2)ecimen. — In Selangor Museum No. 2295/10, skin and skull 

 adult female, East Perlientian Island, September 8, 1910. Collected 

 by C. Boden lOoss; original number, 3517. I have not seen the 

 type-specimen. 



Geographic distribution. — East and West Perhentian Islands off 

 east coast of Malay Peninsula. See No. 38 on map on page 75. 



Diagnosis. — Differs from the other subspecies in its longer tail and 

 lighter color. 



Color. — Based on two specimens loaned by the Selangor Museum, 

 Nos. 2303/10 and 2315/10. The general color of Tupaia lacernata 

 longicauda is essentially the same as it is m the mainland T. lacernata 

 wiTkinsoni, but the ochraceous and tawny ochraceous bands on the 

 hairs are wider and more conspicuous, and the lighter color is slightly 

 in excess of the black; the grizzlmg is coarser, and there is less con- 

 centration of the tawny color on the rump, and the anterior parts 

 have no indication of the slight olivaceous tint seen m T. lacernata 

 wilkinsoni; essentially the same colors are found in the tails of T. 

 lacernata longicauda and wiTkinsoni, but the black is not m excess in 

 T. lacernata longicauda; the under parts of the two forms are essen- 

 tially alike; the hands and feet of T. I. longicauda are more ochraceous 

 than they are in T. I. wilkinsoni. 



Skull and teeth. — No appreciable differences exist between the skull 

 and teeth of Tupaia lacernata longicauda and T. lacernata wilkinsoni. 



Measurements. — "Collector's external measurements of the type: 

 Head and body, 178; tail, 192; hind foot, 44; ear, 16. Cranial 

 measurements: Greatest length, 51.7; basal length, 44.7; * * * 

 greatest cranial breadth, 19.5; zygomatic breadth, 26.2." For meas- 

 urements of two topotypes see table, page 53, and for measurements 

 of additional specimens see Kloss, Journ. Fed. Malay States Mus., 

 vol. 4, p. 193, October, 1911. The average external measurements 

 of 24 adults given by Mr. EHoss is: Head and body, 177. 5; tail, 185.6; 

 and hind foot, 43.5. A few specimens have the tail actually shorter 

 than the head and body, 2304/10, 179, 176; 2315/10, 190, 184, and in 

 one case equal 2214/10, 178, 178. 



Specimens examined. — Two loaned by the Selangor Museum. 



Remarks. — The two treeshrews just described are closely related to 

 one another as well as to the mainland form from the middle of the 

 Malay Peninsula from which they have evidently been derived. 

 Although somewhat more hke Tupaia helangeri in point of coloration 

 than the other subspecies, yet the mammae are 2-2=4. Typical
