THE CROCODILES AND LIZARDS OF BORNEO. 93 



The average length of adults of this species is from eight 

 to ten inches. 



Plentiful, but not so common as M. muUifasciata. 



1 have described the colours of several individuals which 

 are very brilliant when alive. This lizard is easily distinguished 

 from all the others, being very robust in habit, the tail is carina- 

 ted to the tip, and very dark-lDrown, almost black above.

52. — Mahiiia rudis, var. Kuching ensis^ n. sp. S. M. 



Female. — Above, dark brown ; dorso lateral band, nearly 

 black; sides of neck and body to base of tail, closely barred with 

 bright chrome yellow-edged black spots ; chin and throat, greyish 

 white ; chest and rest of under parts, dull brown tinged with 

 yellow. 



This specimen is so distinctly marked and readily distinguish- 

 ed from the true M. rudis. 1 considered it worth separating 

 for the present. Almost appears like a hybrid.

53. — Mahuia Lewisi, n. sp. S. M. 

 Male. — Habit, robust. Above, dark brown ; dorso-lateral 

 streak, pale brown ; sides, dark-green unspotted ; upper and lower 

 lips, chin, throat, chest, and sides of neck, rich orange red ; under 

 part of fore arms, and belly, bright lemon-yellow ; scales of vent 

 and under part of tail, pure silvery-white. 



Mabuia Lewisi n. sp. 



Female. — Above, brown paler than the male ; dorso-lateral 

 stripe, pale brown; sides of body, dark brown; a buff coloured 

 streak from the corner of the mouth to hind limb ; chin and throat, 

 white ; belly, yellowish-g'reen ; under sides of limbs and tail, pale 

 greenish-brown. 



Similar to Mabuia rudis, but the carinations are not so bold, 

 and the points do not overlap like those of M . rudis. It is with- 

 out the four or five longitudinal rows of small black specks on 

 the back, which is alwaj^s present in M. rui:is; and easily dis- 

 tinguished when alive by its bright-red throat, and other colours. 



This fine species I procured on Santubong at about 200ft., 

 others near Kuching. I have much pleasure in naming it after 

 M, J. E. A. Lewis, who always takes much interest, and does a
