miller] seventy new Malayan mammals 9 



irregularly at surface. Lateral stripes clear and sharply defined, 

 the inner black, the outer buff. The width of each at middle is 

 about 10 mm. 



Measurements. — Measurements of type : total length, 485 ; head 

 and body, 205 ; tail vertebrae, 180; hind foot, 46 (43). 



Specimens examined. — Malay Peninsula ; Tanjong Laboha, Trin- 

 ganu, I ; no exact locality, i ; Tioman Island, 12. 



Remarks. — As compared with a series of five skins of Sciurus 

 nigrovittatns from western Java the characters of Sciurus bilimitatus 

 are both pronounced and constant. There is no variation worthy of 

 note, and the specimens from Tioman Island appear to agree in all 

 respects with those from the mainland. In Sciurus nigrovittatus 

 the pale lateral stripe is so ill defined that in some skins it would 

 easily pass unnoticed. Horsfield, in fact, does not mention it. 



SCIURUS PEMANGILENSIS sp. nov. 



Type. — Adult female (skin and skull), No. 112,460, United States 

 National Museum. Collected on Pulo Pemangil, off coast of Johore, 

 June 12, 1901, by Dr. W. L. Abbott, Original number, 1062. 



Characters. — A pallid member of the Sciurus vittatus group some- 

 what resembling Sciurus lautensis of the North Natuna Islands, but 

 smaller and with upperparts a clearer, less yellowish gray. 



Color. — Upperparts a fine inconspicuous grizzle of black and pale 

 very dull buff (or light wood-brown), the two colors about evenly 

 mixed on back, the buff slightly in excess on sides, the general effect 

 throughout very near broccoli-brown. Cheeks and outer surface of 

 legs light wood-brown. Entire upper surface of tail like back, but 

 more coarsely grizzled. Under surface of tail nearly clear, pale, 

 wood-brown (or cream-buff with a slight brownish tinge) except 

 at edges and at tip, where it is grizzled. Underparts and inner sur- 

 face of legs bright ochraceous-buff (considerably more yellow than 

 that of Ridgway), fading to pale wood-brown on chin. Outer 

 lateral stripe buffy white, well defined and about 7 mm. in width. 

 Inner lateral stripe diffuse, about 10 mm. in breadth, its color like 

 that of sides of body but slightly darker and overlaid by a thin wash 

 of ochraceous-buff. Feet dull buffy gray, not noticeably paler than 

 legs. 



Skull and teeth. — The skull and teeth resemble those of Sciurus 

 lautensis except that the rostrum appears to be somewhat broader 

 and more robust. 



Measurements.— Measurements of type: total length, 335; head 

 and body, 185 ; tail vertebrae, 150; hind foot, 44 (41) ; skull, greatest 

 length, 49 ; zygomatic breadth, 28.
