The Tortricidæ, or Short-tailed Burrowing Snakes, are a small family, one portion of which ranges from India to Cambodja, and through the Malay islands as far as Celebes and Timor; these form the genus Cylindrophis. Another portion inhabits America, and consists of:—
Charina (1 sp.), found in California and British Columbia; and Tortrix (1 sp.), in Tropical America.
We have here a case of discontinuous distribution, indicating, either very imperfect knowledge of the group, or that it is the remnant of a once extensive family, on the road to extinction.

The curious nocturnal carnivorous Snake, forming the genus Xenopeltis, and the sole representative of this family, ranges from Penang to Cambodja, and through the Malay Islands to Celebes.
