the body, and the plates with which their jaws are 

 furnished, are not hollowed into fossets. 

 Such is. 



The Boa Constrictor, Lin. Lacep. II. xvi. 1, Seb. I. 

 xxxvi. 5, liii. III. Ixxxviii. 5, xcix. 1, CL Devin., 

 or Boa Empereur of Daud.* 



To be recognized by a broad chain, formed alter- 

 nately of large blackish spots, irregularly hexagonal, 

 and of pale oval spots emarginated at both ends, 

 which predominates along its back, and constitutes 

 a very elegant drawing. 



2. Others have scaly plates from the eyes to the 

 end of the muzzle, and are destitute of fossets to the 

 jaws.

Brown, a double series of round black spots along 

 the back, and eye-like spots on the sides. 



* Daudin believed that this boa was found in the old continent, but it 

 certainly belongs to Guiana — M. Levaillant and Humboldt have brought 

 it thence. Prince Maximilian has found it in Brazil ; M. Levaillant also 

 brought from Surinam the two following species, and every body knows 

 that the bojobi is from Brazil. I do not believe that the ancient continent 

 possesses any true boas of a large size. The very large serpents of India 

 and Africa are pythons ; the name of devin (conjuror) is derived from an 

 erroneous attribution to this serpent of what is related of certain large 

 adders, of which the negroes of India make their fetishes.
