 quickness of movement when attempting to escape. I am

 differs in form, arrangement of vomero-palatine teeth, and color. Head 

 broader and flatter than in longicaudus, contained in distance to groin 

 5 to 5.5 times. The distance from snout to axilla in distance to groin 

 3.5 times against 4 times in longicaudus. The series of vomero-palatine 

 teeth runs forward to a point in advance of the hinder border of the 

 choanae, or even to its anterior border, and then turns abruptly out- 

 ward and backward, so as to produce the form of a hook. Costal 

 grooves 13 or 14. Snout truncate. A distinct gular fold. Eyes prom- 

 inent. Tail long and compressed, containing head and body 1.5 times.

Color. — The ground color varies from orange to vermillion red. The 

 head and body are irregularly spotted with black dots about the size 

 of the pupil, or larger. The tail and the upper surface of the legs are

 specimens there is on each dorso-lateral region a row of black spots, 

 which begins over the arm and runs back on the tail. In the middle 

 of the back there is an irregular row of spots. 



Size. — From tip of snout to vent 65 mm.; from vent to end of tail 

 88 mm.; total length 153 mm.
