of a gentleman at Penang, and afterwards found wild at Singapore 

 and in the woods near Bencoolen. " The Penang animal was described 

 several months before ferruginea under the specific designation glis. 

 No specimens collected at Singapore by Raffles are known, so that it is 

 perfectly justifiable to take the above specimen as the type. It has 

 recently been made into a modern study skin and is in fair condition. 

 Some hair has slipped from about the head, legs, and base of tail. 

 The color seems well preserved. The skull is nearly perfect; the oc- 

 cipital region, zygomata, and bullae being slightly injured. 



Geographic distribution. — Malay Peninsula south of about latitude 

 7^° N., including the island of Singapore; and most of island of Su- 

 matra. For exact localities from which specimens have been exam- 

 ined, see table, pages 43, 44. See No. 6 on map on page 75. 



Diagnostic characters. — A bright-colored member of the group, with 

 upper parts of head and body distinctly ferruginous, tail a grizzle of 

 buffy and blackish, rather distinctly different in color from body. 



Color. — Upper parts of head, neck, and body, and outerside of legs 

 a grizzle of ferruginous or chestnut and blackish, tail both above and 

 below a grizzle of buffy and blacldsh, the black in excess above and 

 the buff below, especially along the middle line; underparts includ- 

 ing inner side of legs various shades of buff, often with dark bases 

 of the hairs showing through; feet a fine grizzle of buffy and blackish, 

 the latter color in excess; shoulder stripe moderately conspicuous, 

 buffy in color. 



SlcuU and teeth. — These show no special distinguishing character- 

 istics. See plate 8, fig. 6, and figures 4 and 5 on page 33. 



Measurements. — Type: Hindfoot, 45 mm; condylobasal length, 51; 

 zygomatic width, 25 ±; width of braincase, 20; maxillary toothrow, 

 20. Usual measurements of adults: Head and body, 175-200; tail, 

 150-175; hindfoot, 42-47; condylobasal length, 47-49; zygomatic 

 width 25-27; width of brain case, 19-20; maxillary toothrow, 18-20. 

 For measurements of all specimens examined, see table, pages 43, 44. 



Remarlcs. — Twpaia glis ferruginea has one of the largest areas of 

 distribution of any of the forms in the family, and appears very con- 

 stant in its characters. I have been able to find no essential differ- 

 ences between specimens from the Malay Peninsula and the island of 

 Sumatra. This case is exactly paralleled by Tragulus napu.^ 



An old specimen, British Museum, Register No. 79.6.28.15, collected 

 at Pajo, Sumatra, by Carl Bock, approaches very closely Tupaia 

 phsRura. 



Specimens examined. — Sixty in the United States National Museum, 

 37 in the British Museum, 1 in the Genoa Museum, 3 in the Berlin 

 Museum,
