9. colubrinus, Gthr. The validity of this species has been 



fully acknowledged by Dr. Wucherer. He has sent two specimens 

 in spirits, one of which measures 3 feet 8 inches in length ; another, 

 sent off alive, perished on the voyage. Dr. Wucherer has observed 

 that the scales of all the species of Xenodon have a small colourless 

 spot near the tip ; it is especially distinct in X. colubrinus. The 

 West Indian species of Dromicus have this spot yet more distinct. 

 All the species of this genus are very savage and apt to bite ; they 

 frequent dry places ; their food, however, consists in frogs.
