Genus GEORGIA, Baird & Girard. 



Gen. Char. Vertical plate short, very broad. Superciliaries 

 broad, and the cornea scarcely visible from above. Head rather 

 high. "Outline of the top of the head very convex. Two postorbit- 

 als ; one large anteorbital. Two nasals, very short. Kostral broad, 

 low. Dorsal rows of scales perfectly smooth, in 17 rows, overlap- 

 ping or imbricated. Postabdominal scutella entire. Postfrontals 

 much larger than the prefrontals. Size of the animal very large. 

 Color black. 



This genus has a strong resemblance to Bascanion, from which it 

 differs by its stouter form, much broader vertical, one anteorbital, 

 undivided postabdomidal scutella, &c. From Ophiholus it is dis- 

 tinguished by the broader superciliaries, deeper head, much imbri-* 

 cated scales, &c.
