COSYMBOTUS 59 



Barbour has regarded the specimens from Java as belonging 

 to H, gamotii, and de Rooij has included Hawaiian specimens 

 under the same name as those from Java, Borneo, and the 

 Asiatic mainland. Whether Stejneger is correct or not I can- 

 not say. His statement, ''the true H, garnotii appears to be en- 

 tirely destitute of femoral pores," is not conclusive.* 

 Genus COSYMBOTUS Fitzinger 



Platyurus Oken, Allgem. Naturges. 6 (1836) 641. 

 Cosymbotus Fitzinger, Syst. Rept. (1843) 104. 

 Crossurus Giraud, U. S. Expl. Exped., Herp. (1858) 281. 

 Nycteridium Gunther Rept. Brit. India (1864) 111. 



Digits partly webbed, well developed, all with terminal, free, 

 compressed, clawed phalanges; lamellae below digits divided; 

 body with a flaplike lateral expansion ; tail flattened, with lateral 

 denticulate fringe; pupil vertical; preanal and femoral pores 

 in continuous series. 



This genus differs from Hemidactylus in the presence of a 

 cutaneous expansion along each side of the body. There is but 

 one species.

 garnotii from Ifugao, Luzon, which has distinct, well-developed series of 

 preanal pores. .
