The Terehellmn lives in rather deep water, and is found 

 in the China Sea and among the islands of the Indian 

 and Philippine Archipelagoes. In its mode of progression 

 it I'esembles the Strombi, rolling the shell over and over, 

 and performing a series of irregular jumps; when first 

 taken from the water it will even leap several inches from 

 the ground. It is extremely shy and sensitive in its 

 habits, poising the shell in a vertical position, and pro- 

 truding the longer telescope eye (for, singularly enough, 

 one eye-pedicel is longer than the other) from the notch 

 in the front of the shell ; it will thus remain perfectly 

 immovable until assured of security, when it begins to 

 roll over and examine the ground with its rostrum.
