rows, which has been the usual method adopted. The number ia 

 each case will appear much less, but it will be recollected that this is 

 owing to the scales of one row being alternate with those of the next 

 one. 



M. PENTADACTYLA, Linn, {inacroura, Desm.) 



Each transverse row of scales composed of three on each side of 

 the median one; scales striated at the base, smooth at the end, the 

 striated part distinctly separated from the smooth portion ; ends of 

 the scales simple ; under parts naked ; tail very broad at the base, 

 about equal to the body in length ; fore-feet five-toed, the claw of the 

 medius much the largest, that of the annularis next, that of tlie index 

 much less, the other two very small ; hind-feet with lengthened claws; 

 limbs scaled to the bases of the claws. 



M. JAVANICA, Desm. 



Four scales on each side of the median one in each transverse row, 

 the lower ones on each side, and the lateral ones beneath the tail, 

 keeled and pointed at the ends ; tail broad at the base, equalling the 

 head and body in length ; mider parts with short white hairs ; Umbs 

 scaled to the bases of the claws ; fore-feet with the middle claw 

 largest, the index a Httle less than the annularis, the others very 

 small ; hind-feet with lengthened claws. 



M. Temminckii, Smutz. 



Body altogether very broad ; scales broad, three on each side in 

 every transverse row, striated to the tips which are rounded, none of 

 them carinate ; imder parts naked ; tail about the length of the body, 

 broad and rounded at the end ; limbs scaled to the bases of the claws; 

 fore-feet with the middle claw largest, the two next less, the remain- 

 ing two much less ; those of the hind-feet vertical, truncated. 



M. TETRAD ACTYLA, LiuD. {Africanay Desm.) 



Scales large, three on each side in every transverse row, striated to 

 the tip, which is square, with a point projecting from the middle, 

 the lower ones at the sides and the lateral ones beneath the tail cari- 

 nate ; tail double the length of the body, a little narrowed at the 

 base, soon becoming broad ; limbs only scaled at the base, then 

 covered with black hairs like the under parts; fore-feet with the 

 middle claw very long and compressed, the index and annularis much 

 less and nearly equal, the minimus less still, the inner toe verv' small; 

 hind-feet with lengthened claws, nearly equal. 



M. MULTiscuTATA, Gray, Proc. Z. S. Feb. 1843. 



Five scales on each side of the median one in every transverse row • 

 scales striated to the tip, which is square, wit'\ a median point; 

 those on the sides of the trunk and limbs, and the lateral ones be- 

 neath the tail, carinate ; tail nearly double the length of the bodv, of
