CLASS III. — REPTILIA. 



XXIX 



ORDER III.— Ophidia. 



This order is primarily divided into three families : 1 . the Snakes, 

 Anguis ; 2. the true Serpents; and, 3. the naked Serpents. Of 

 these, the 1st and 3d contain each but one genus ; the 2d contains 

 all the rest, and, as these differ in several respects, is subdivided, 

 1st, into two tribes, the Double-marcheurs, that is, those that move 

 with either end foremost, and the Serpents proper, which always 

 advance with the head in front. The Serpents proper are then di- 

 vided according as they are non-venomous or venomous ; and after- 

 wards these latter according as they have isolated fangs, or fangs ac- 

 companied by the ordinary jaw teeth. Finally come the division 

 into genera, subgenera, and species ; but of all these our plan and 

 limits will only permit us to notice the families, genera, and subge- 

 nera, illustrating as usual vidth a specific example of each.
