140 BARBOUR: ZOOGEOGRAPHY. 



the case in A . contortrix and A . piscivorus; in both of these it disappears before 

 adult size is reached. The largest specimen measured by Boulenger {loc. cit., 

 p. 528) was 900 mm., total length of body and tail. In a series of eight examples 

 taken near Buitenzorg during March and April, 1907, one measures 1,030 mm. 

 total length. In all, the number of rows of scales was 21 ; ventrals ranged from 

 144 to 157, and subcaudals from 38 to 53. 



The history of our knowledge of this form is curious. When Boulenger, 

 in 1896, wrote vol. 3 of the British museum catalogue, this species was definitely 

 known only from Java, whence Reinwardt had taken it, and whence the example 

 for Russell's (Account of Indian serpents, 1801, 2, pi. 21) figure had come. 

 There was a specimen known bearing the label "Siam." Six years later the 

 first part of the Zoology of Fasciculi Malayenses appeared, papers based on the 

 collections of Annandale and Robinson in Perak and the Siamese Malay States. 

 For this Boulenger prepared a list of Malayan reptiles as an appendix to his 

 study of the collections entrusted to him. He notes that A. rhodostoma does 

 occur in Siam, whence a specimen has been received by the Christiania museum ; 

 and also records it from Biserat, Jalor, Malay Peninsula. Annandale says that 

 it is not rare, and it is remarkable that it remained so long undiscovered. 

 Strangely, it has not been found in Sumatra as yet. As Boulenger notes, a 

 parallel case to this discontinuous distribution is afforded by Geoclemys^ sub-- 

 trijuga (Schl. en Miill.), and other species which are mentioned passim. 



I got a series of specimens from Buitenzorg; and Bryant took thirty-one: — 

 one at Gunung Bunder on Mt. Salak, elevation 2,200 feet; eighteen at Depok; 

 eleven at Buitenzorg; and one at Daru in Bantam.

This form in western Java is an inhabitant of deep forests at high levels. 

 Major P. A. Ouwens of the Buitenzorg museum told me that it was never taken 

 near Buitenzorg. On the higher volcanic peaks near Soekaboemi it occurs 

 sparingly. Two specimens were taken at an altitude of from 4,500 to 5,000 feet 

 during April, 1907. Bryant took it only on Mt. Salak, where he got six speci- 

 mens. One of my specimens is now in the Museum of the Department of agri- 

 culture at Buitenzorg, and the other is before me. The color has hardly changed
