Family 2.— TOKTKICID^E. (3 Genera 5 Species.) 



General Distribution. 



The Tortricidce, 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. 



Family 3.— XENOPELTID^E. (1 Genus, 1 Species.) 



General Distribution. 



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.
