or fallen tree-trunks or damp decaying leaves in localities sheltered 

 from the sun, but supplied with abundance of moisture. 



Preservation. — Great care must be taken in killing specimens of 

 Peripatus. The most satisfactory method is drowning in water. 

 To hasten the process a few drops of ammonia may, if desired, 

 be added to the water. If, while still alive, the animal be plunged 

 direct into alcohol or any other preservativ^e fluid, the body and 

 limbs contract and the tissues shrink, so that the specimen is 

 rendered less valuable for museum or anatomical purposes. During 

 the process of drowning the body becomes fully distended. In this 

 state it may be transferred to alcohol.
