152 ZOOLOGY. 



8. AmpTiisbcena. Rings on the body and tall. 



All the species belonging to this genus, are without scales, 

 having smooth cylindrical bodies, of equal thickness through- 

 out, and the extremities so obtuse, that the head is scarcely

9. Cwcilia. Wrinkles on the body and tail ; the upper lip 



furnished with two tentacula. 



Natives of South America, and India. 



Having, in enumerating the essential characters of the 

 genera, given such general outlines of their history, and 

 ceconomy, as will enable the Naturalist to arrange them into 

 noxious, inoxious, and useful ; as also, to put him on his 

 guard against such as are venomous, we proceed to point 

 out the methods to be adopted in the preservation of the 

 skins and shells, of the various kinds comprised in this class. 



The larger kinds of Turtles and Tortoises, should have the 

 under part of the throat opened, leaving the skin surround-

 much of the skin as can be conveniently left adhering, may 

 be taken off, these should be cleared of all blood and impu-

 for a few hours, after which, it should be removed into a jar,
