The Tortricidse, 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 CylindropMs. Another portion inhabits America, 

 and consists of: — 



Charina (1 sp.), found in California and British Columbia; 

 and Tortrix (1 sp.), in Tropical America.

 remnant of a once extensive family, on the road to extinction.
