Variation. — Almost all specimens examined haye a third, 

 outer pair of chin shields, about one-third the size of second 

 pair and joining it, but separated from the labials by one or 

 two rows of small scales. The posterior edges of the chin 

 shields form rather regular curved lines. The preanal and fem- 

 oral pores vary from seventeen to twenty-one on each side. 

 Stejneger gives the variation as fourteen to nineteen on each 

 side. In certain specimens there is a rather distinct angle 

 formed by the junction of the femorals and preanals. The pores 

 are differentiated by their arrangement, being obliquely placed 

 in opposite directions. 



Color variations are marked. Specimens taken in the forest 

 under the bark of trees are usually very much darker, in some 

 cases blackish, with very numerous, dark brown or blackish 

 blotches on back and sides and numerous, scattered, small white 

 spots; labials spotted with white; belly powdered with brown; 

 several specimens examined showed one or two small scales in- 

 serted between the supranasals. 



Young specimens also are darker, with a row of round yellow 

 dots beginning on snout and continuing in two lines along mid- 

 dle of back to tail; usually there are a few irregular brownish 

 blotches and numerous yellowish flecks ; tail barred with brown- 

 ish, with a few whitish spots near tip. 



Remarks. — This species is widely distributed in the Philip- 

 pines, probably occurring on all of the larger and most of the 

 smaller islands. I have examined more than a hundred speci- 

 mens, from forty-two localities. The type locality is Manila, 

 but the species is widely distributed, having as wide a range 

 in the Pacific as Hemidactylus frenatus. It is found also in 

 Mexico. Its introduction into Mexico was probably not earlier 

 than the sixteenth or seventeenth century when direct commerce
