PALPEBRAL BOA. 



Boa Palpebrosa. B. Albida, glauco fasciataj palpebris extantibus. 

 Whitish Boa, obscurely fasciated with grey, with prominent 

 eyelids. 



Schlingende Natter. Merrem Beytr, Zur, Naturg, 2. 20. t, 3. 

 Abdominal scuta 312, subcaudal 51, 



Length about fifteen inches : head rather large, 

 and covered in front with large scales : eyebrows 

 remarkably prominent : body thick in proportion 

 to its length : colour pearly grey above, with ob-^ 

 scure transverse dusky or blueish undulations: be- 

 neath pale yellow-brown, with a small transverse 

 oval black spot at the edge of every abdominal scu- 

 tum, and a middle range of similar spots from the 

 vent to the end of the tail, the extremity of which, 

 for about the length of half an inch, is furnished 

 with divided scales : native country unknown : 

 described by Mr. Merrem. This snake I have 

 arranged among the Bo^ rather than the Colubri, 

 on account of the vast predominancy of the Scuta 

 over the Squamce on the under surface of the tail,
