LEPIDODACTYLUS PLANICAUDUS, new species. 



Diagnosis. — Closely allied to Lepidodactylus luguhris., but tail much 

 more depressed, broader, less tapering, with a lateral flap-like free 

 margin and less distinct verticillate arrangement of the caudal scales; 

 digits wider in proportion to their length. 



Hah'dat. — Mindanao, Philippine Islands. 



Type.—Oni. No. 34T46, U.S.X.M; Mount Apo, Mindanao, between 

 4,000 and 6,000 feet altitude; Dr. E. A. Mearns, collector; June-July, 

 1904. 



liemarli's. — Peters has already- described a Lejjidodactyl >is lahkdis 

 from Mindanao, which is also said to be closely allied to Z. luguhris. 

 It has, however, a " cylindrical tail," and diflers from it, consequentl}^ 

 in just the opposite way of our new species. In the latter the tail is 

 unusually depressed and instead of tapering gradually toward the tip, 

 the edges are practically parallel for quite a distance and then taper- 

 ing ofl' much more quickly. Instead of the "sharpish" lateral edge 

 of the Polynesian L. 1 nguhrfs., our specimen has a lateral free margin 

 edged with a series of nearly uniform small spines which show no 

 definite verticillate arrangement. The digits are wider and clumsier, 

 hence look shorter that in L. JugnJyris., and the lamina? under the basal 

 joints are better defined. There are 12 upper and 11 lower labials, 

 much as in Z. htgid>rh^ consequently less than in Z. hdrialis. The 

 first series of slightly enlarged chin scales which join the mental and 

 the anterior lower labials are rather smaller than the next row, while 

 in Z. luguhris the proportion is reversed, those nearest the mental 

 being the largest.
