Type. — Not known to exist. 



Type-locality. — Riceboro, Georgia. 



Distribution. — From the Atlantic coast south of Dismal Swamp to 

 Miami, Florida, and Washington, Mississippi. Zonal range: Lower 

 Austral. Vertical range: Sea level to between 100 and 500 feet. 



Diagnosis. — Similar to fusca, but a row of light spots on sides, 

 slimmer, belly mottled, dark. 



Description. — Vomerine teeth as in fusca. Parasphenoid patches 

 shorter, separated from the vomerines by twice the length of one 

 of the vomerine series. Tail similar to that of fusca, but slightly 

 longer. The appressed toes fail to meet by four to four and a half 

 intercostal spaces. The head length is from four to four and a half 

 in the length of head and body. The head width is five and two- 

 thirds to six in the length of head and body. The size is smaller 

 than in fusca. The legs are weak and the tail is long. The head is 

 narrower than in fusca. 



The color is like that of fusca, but generally darker, especially 

 ventrally. The belly, however, is always mottled. There is a hue 

 of hght spots along the sides just above the insertion of the legs. 

 This Une is continued into the tail. The hght spot between the eye 

 and the angle of the jaw is especially noticeable in this form. It 

 is said that these hght spots are red in life. I have seen only alco- 

 holics in which the color had faded. 



Habits. — Nothing has been pubhshed on the habitat, food, or life 

 history of this form save Lonnberg's (1894) statement that he found 

 one in Florida "under a log in a wet hammock." 



Its habits are probably similar to those oi fusca. No larvae have 

 been seen. The males lose the vomerine teeth at a length of about 

 90 mm., head and body 45 mm. 



Remarlcs. — Intergradcs with fusca. Its relationships with fusca 

 have been discussed under that form.
