Type locality: — Java. 



Twenty-five specimens taken in Buitenzorg, where the species is very 

 abundant, and one at Tjibodas, Java, show great variety in color and markings. 

 Bryant's series of thirteen from Buitenzorg, and one from Gunung Bunder, Mt. 

 Salak, vary similarly. I agree completely with the observations of Flower 

 (Proc. Zool. soc. London, 1896, p. 906) as to the value of these markings for 

 determining color varieties. The condition after killing and preserving is entirely 

 dependent on the phase of color which had been assumed by the animal just before 

 death. They change color and color-pattern with considerable rapidity. Flower , 

 in a subsequent paper (Proc. Zool. soc. London, 1899, p. 898-899) notes that they 

 seem to breed at almost all times of the year. All of these Javanese individuals 

 have the skin of the head more or less involved in the cranial ossification. This 

 seems to begin when the frog is about li" long, and when the creature is 2" long 

 the process is complete. 



Five specimens from Mt. Wuchi, Hainan, though not fully adult seem to 

 have a much less extensive ossification than Javan examples of the same size. 

 This may be due to the fact that these specimens were originally preserved in 

 formol, a preservative which usually should be carefully shunned, unless the 

 collector is skilled in its use. 



A wide-ranging form over southeastern Asia, the Philippines, Sumatra, 

 Nias, Banka, Natuna, Borneo, Java, Madura, Timor, Sumba, Salayer, and 

 Celebes. Reported once from Ternate, no doubt incorrectly.

Type locality: — Mt. Tjiserupan, west Java. 



Bryant had a single fine example from Tjibodas, Mt. Gede, and also one 

 from Buitenzorg. 



The species is confined to Java.
