scales three. Supraoculars forming a disc of seven smooth scales, 

 which is in contact throughout its inner border with the supraorbital 

 series. Loreals in five rows. 



The muzzle is rather short, and the extended hind limb reaches to 

 the orbit. There are thirteen laminae beneath the second and third 

 phalanges of the third and fourth toes. 



The only specimen is a female, and it is greenish-gray with a 

 brown band on each side of the vertebral line, which is similar in color 

 to the sides. Throat with longitudinal series of blackish spots. 



Length to vent, 44 mm. ; do. to line of meatus auditorius, 14 mm. 

 Length of fore limb, 19 mm. ; do. of hind limb, 34 mm.; of hind 

 foot, 14 mm. 



This species is remarkable for the reduction in the number of its 

 head scales. It resembles no other species nearly, unless it be the 

 AnoUs krugii Peters, of Porto Rico, which I have not seen. There 

 are numerous discrepancies in the description of the latter. For in- 

 stance, in A. krugii, the ventral scales are keeled, the superciliaries 

 are separated by a row of scales; the supraorbitals are keeled; 

 there are four enlarged dorsal rows, and the color is quite different. 



Amiva thoracica Cope. 



"A common and conspicuous species, especially in the northernmost 

 of the Bahama Islands. Like its allies this is essentially a ground 

 inhabiting species, living among the loose coral boulders, in the 

 crevices of which secure shelter and concealment may be found. 

 They love to lie on stones basking in the warm sunshine, but are ever 

 alert and dart away like a flash, their course being indicated by a 

 blue streak. They are extremely difficult to catch, and although 

 very abundant on Cat Isl., and almost equally so on Eleuthera, only 

 a very few specimens were taken.

"A most beautiful species of essentially arboreal habits. Widely 

 distributed, but apparently not very common anywhere. They are 

 found among the smaller trees and bushes, leaping actively about
