nent, and the olecranon process of the ulna is shorter. The femur, 

 tibia, and fibula are proportioned about as they are in the two preced- 

 ing- g-enera, but the metatarsals and phalanges are relatively longer. 

 The scapula of Atheru7"us is broad.

Distr'dmt'um. — Malay Peninsula, Burma, and perhaps various 

 Malayan Islands. 



Color. — General effect of top of head, upper back, and of feet, 

 Ridgway's drab, rather dark. The heavier spines are a blackish 

 brown. On the sides, thighs, and underparts the spines have dull, 

 dirty whitish bases and subterminal apical bands, with a drab or drab- 

 gray band between them, and a very slight drab-gray apex. The 

 chin and upper throat are particularly light, as well as an ill-defined 

 band across the chest. The light color of the bases and of the subter- 

 minal rings of the spines show to a marked extent on the sides and 

 underparts. The tuft of bristles at end of tail vary from dirty whit- 

 ish to a dirty cream buff. 



Measurements. — See table, page 593. 



Sj)ecimens examined. — Four, from Trong, Lower Siam. 



«Seba's figure shows an animal much less spiny than any Malayan specimens I 

 have seen. The desiTiption of the tail does not agree with specimens of this genus 

 in the U. S. National Museum. Seba likens the swelling on the caudal bristles to 

 grains of rice inclosed in an envelope. In the specimen at hand each bristle, while 

 hollow, is flat and alternately widened and contracted laterally in one plane only, 

 and the expansions are much longer than are the enlargements shown in Seba's 

 figure. It is barely possible that the animal usually designated as Atherurus 

 macrourus (Linnsus) is really an undescribed species. At least it would so appear 

 if Seba's account is at all accurate.
