 clothed with '■thin harsh adpressed hair projecting 1^ inch beyond the 

 bone " ( P. /. S. 1870, p. 227. under Macu'Uis erythraei's). 



(Jther groups are the "stump-tailed" section mchiding ardouks, 

 of which rafescens Anderson, and kariiianili Troues.sart, both recorded 

 from Siam, are possibly subspecies ; the " pig-tailed " group, containing

 (^=l.eoninas) all seem to be local representatives; and the long-tailed 

 '■ crab-eating " moidieys, iras Cuvier, to examples ol which from Penin- 

 sular Siam, Elliot has given the name uqnlalig.
