Remarks. — This species stands much in the same relation to 

 B. burksi as B. schadenbergi does to B. gracilis. The following 

 differences are present: The mental is larger, the arrangement 

 of the chin shields is essentially different, and the postmental is 

 in contact with a single labial instead of with two as in B. burksi. 

 Several other minor differences are evident on a comparison of 

 the two species. 



Described from No. 1151, private collection; Los Baiios, La- 

 guna, Luzon, on the side of Mount Maquiling, elevation about 

 100 meters; April 10, 1917; E. H. Taylor, collector. 



Note: Since this paper has gone to press, two apparently 

 new species of the genus Brachymeles have been discovered in 

 the Sulu Archipelago. One is a pentadactyl form, the other 

 has lost all external vestiges of limbs. They will be described 

 in a forthcoming paper on Sulu reptiles.
