54 MR. C. BODEN KLOSS ON 



in breadth, not veiy sharply margined, and not extending to the 

 limbs. Tail dark toith a white tip. 



Colour. — A variable clay, the dorsal area everywhere much 

 darkened by the bistre tips of the spines ; this colour extending 

 over the whole of the limbs, across the chest in the form of a 

 broad gorget, the hairs of which have distinct grey bases, and 

 over the entire muzzle, which is rather browner. White of 

 under surface reduced to a comparatively narrow band running 

 from the axillae to groin, 25-30 mm, wide, and to an isolated 

 patch confined to the throat. Fore and hjnd feet pale. Tail 

 about the same length as head and body, dark for the basal 

 two-thirds or thpee-fourths, the tip white, not sharply defined 

 from the rest, 



Skull and I'eei^. ^-Generally resemble the mainland race, but 

 with the nasals broader postei'iorly, their outer margins 

 vStraighter; the palatal foramina distinctly larger, being both 

 longer and broader ; anterior zygomatic plate broader ; and the 

 zygomatic breadth a. little greater, 



Mea&urements, — i]ar of type, 24'5 mm, For other measurements 

 see table, p. 74. 



Specimens examined. — Nineteen from the tvpe-locality, 



Remarks. — Its dull colour, redvTced white areas, and non- 

 bicoloured tail render this race of Epim,ys surifer the most 

 distinct known to me. All the Indo-Ohinese forms here 

 described are less brilliant in colour than any of the Malayan 

 races of the rajah-surifer group, and their tendency to dullness, 

 manifesting itself strongly in the island fornix, culminp-tes so 

 notably in the Koh Kra animal, that, with its other characters in 

 addition, one woiild readily accept it as a distinct species w^ere 

 it the inhabitant of a large land^mass and not of a little satellite 

 islet,

Type, Adult male (skin and skull), No, 1586/C.B,K. B.M. 

 No, 15,11,4.121, Collected on Koh Klum, S.E. Siam, 18th 

 December, 1914. 



Diagnosis. — Like E. s. ealipsis above, but rather more darkened 

 down the median line of the back. Below the white area rather 

 broader, but not to the extent of the more typical forms, and 

 extending a little way across the gi'oin on to the thigh. "Wrists 

 very pale, but separated from the chest ; white area of neck a little 

 larger, but confined to the throat. Gorget clearer in colour and 

 rather less distinct, the grey bases of the hairs not visible. Tail 

 shorter than head and body ; bicoloured with a white tip. 



Skidl and Teeth, — Like those of E. s. eclipsis, but the palatal 

 foramina smaller, about the same length as the mainland form, 

 but broader; the interorbital breadth markedly greater than 

 either, and the anterior zygomatic root broader. 



Measurements. — Ear of type, 24 mm. For other measurements 

 see table?, p, 74.
