ones of similar form, but with white centres, on the 

 sides, while on the abdomen are scattered several 

 oblong spots and marks, interspersed with smaller 

 specks and variegations. It is a native of several 

 parts of South America, and, like other large 

 snakes, is occasionally eaten by the Indians.

THIS also grows to a large size, though not 

 equal to either of the former species, from which, 

 as well as from most others, it may be easily dis- 

 tinguished by the regular distribution of its co- 

 lours ; the general cast being ferruginous, darkest 

 on the back, where it is marked by a continued 

 series of very large blackish circles from head to 

 tail ; while along the sides are interspersed several 

 kidney-shaped blackish spots with white centres : 

 the head is a lengthened form, and is marked by a 

 black longitudinal and two lateral bands. This 

 animal is a native of South America, and is ex- 

 tremely well figured in the work of Seba. In the 

 British and Levcrian Museums are specimens pre- 

 served in spirits.
