Sulu, Palawan, and Luzon. Of more than sixty specimens 

 examined none is as large as any of the six specimens in the 

 Negros collection. 



The number of scales varies from thirty to thirty-six. The 

 relation of the intemasals varies; in many specimens they are 

 in contact, but in the larger number they are separated. 



Remarks, — The species is an extremely common one, though 

 it probably does not occur with as great frequency as does M. 

 multicarinata. The females give birth to from five to ten young 

 at a time. One female from Negros contains ten embryos. 

 These lizards feed largely on crickets and other similar insects. 

 Many of them occupy burrows. Known from all the large 

 islands, and they probably occur on most of the smaller ones.
