120 BARBOUR: ZOOGEOGRAPHY. 



caught at Sindanglaia, in the Preanger region of Java, there was a single adult 

 example of this rare form. It constitutes an addition to the ophidian fauna of 

 Java, for it was previously known only from Singapore and various localities in 

 Sumatra. Probably this form will prove to be separal)le into three races. The 

 Singapore specimen, now in the Indian museum at Calcutta, has a small number 

 of ventral scales, V. 129, C. 31. The Sumatran specimens have more: — V. 

 142-168; C. 13-24. In the single known Javan example there are V. 190, C. 21. 

 In this specimen also the rostral is broader than deep, and the diameter of the 

 eye is less than the distance from the mouth. 

 Range : — Singapore, Sumatra, west Java. 



Calamaria virgulata Boie. 



BoiE, Isis, 1827, p. 540. Boulenger, Cat. snakes Brit, mus., 1894, 2, p. 340-341. 



Type locality: — not definitely stated, but a citation to the "Erp. de Java," 

 which never appeared, leads me to suppose that the specimens came from Java. 



Three specimens of this form, which Boulenger calls var. C, were taken near 

 Sindanglaia, Java, on the slopes of the twin volcanoes Pangerango and Gedeh at 

 altitudes varying from 3,500 to 4,500 feet. Ventrals, 164, 166, 180; subcaudals, 

 19, 25, 26. This species seems to replace to some extent C. calamaria, for about 

 Buitenzorg the latter is common, while no specimens of C. virgulata were seen. 

 Probably this form is an inhabitant of a life-zone higher than Buitenzorg; I have 

 pointed out that this is also true of other species. The specimens in the British 

 museum which have definite locality records seem to bear out this conclusion. 

 Thus, there are specimens from Fort de Kock in the Padang Highlands, and also 

 from Mt. Singalang in Sumatra. Menado in Celebes lies near highlands where, 

 as they offer the best opportunities for collecting, Dr. Meyer's examples were 

 probably taken. Two out of three of the Javan specimens bear no data. One 

 is from Rarahan, but the altitude of this locality I have not found. 



Known from Sumatra, Java, and Celebes.

Type locality: — Sintang, Borneo. 



A single specimen of this rather rare and apparently dichromatic form, 

 M. C. Z. 5,241. This species is now known from Sarawak, and also from a 

 number of localities in Dutch South Borneo.
