1399.] EEPTILBS OF THE MALAY PENINSCTLA AKD SIAM. 649 



Fai (near Muok Lek, elevation 900 feet) ; one w:is given me as 

 having been caught in Bangkok ; and there were nine in the store 

 o£ the Siamese Museum, supposed to have been collected by the 

 late Dr. E. Haase at Chantaboou. 



Description. On comparing these latter specimens with the 

 description of this species in the British Museum Catalogue, these 

 points were noted : — 1st, in some individuals the fifth and sixth 

 labials appear welded into one large shield beneath the eye. 2nd, 

 the number of scales round the body appears lai'ge, 40 to 50. 3rd, 

 the hind limb when adpressed is longer, reaching from just in front 

 of the axilla to the shoulder; in the Bangkok specimen it also 

 reaches the shoulder. 



Colour (in spirit). Brown or olive-brown above, with more or 

 less distinct darker and lighter spo^s, sometimes forming two irre- 

 gular dorsal series of small black spots ; a very dark brown lateral 

 line, extending from the nostrils, througli the eye, above the ear, 

 and on to the tip of the (unreprodiiced) tail ; this dark line is more 

 or less spotted with white, and edged below (sometimes also above 

 narrowly) with white, and on the tail it is vandyked : flanks dark 

 brown, spotted with white ; lower surfaces pale yellow or white. 



Size. Total length 171 mm. (snt. to vnt. 65 ; tail 106). 



Hah. Eastern Himalayas (Sikhim), Northern Bengal, Assam, 

 Burma, Andaman Islands, Siam, Malay Peninsula. 



81. Lygosoma olivaceum (Gray). 



Lijqosoma olivaceum, Blgr. Cat. Liz. iii. p. 251 ; S. Elower, 

 P. Z.'S. 1896, p. 874. 



Recorded from Singapore, Penang, and the Peninsula. 



Hah. Tenasserim, Nicobars, Malay Peninsula, Sumatra, Java 

 Borneo, Philippines. 



82. Lygosoma ateocostatum (Lesson). 



Mabouya jerdoniana, Stol. J. A. S. B. 1870, p. 172. 



Lygosoma jerdonianum, Blgr. Cat. Liz. iii. p. 300. 



Lygosoma atrocostatum, Blgr. op. cit. p. 295. 



The type of Jerdon's Skink was caught by Stoliczka on the little 

 rocky island of Palo Tikus Kechil, which lies off the north-east 

 coast of Penang. I twice visited the island to try to obtain another 

 specimen. On the first occasion ,in Nov. 1896, not a skink was seen, 

 but on the second, in April 1898, after our whole party had hunted 

 unsuccessfully all through the middle of the day, at about 4*30 p.m., 

 as we x's ere returning to our boat, I saw a skink on a granite 

 boulder on the beach, which I shot, and found it agreed completely 

 with Stoliczka's description. The only other reptiles we obtained 

 on the island were the common House Geckoes, GeJiyra mutilata 

 and Hemidactylns frenatus. 



Colour (in life). Above, olive-green and bronze, beautifully 

 mingled. Below, throat pale lilac-grey, body and limbs orange, 

 tail greenish yellow.
