The Tortricidae, 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.
