Rhodona (RhodonidcE). Rostral plate rather produced, large de- 

 pressed, with a rather sharp edge ; feet rudimentary ; nostrils supe- 

 rior in the centre of an oblique triangular scale, occupying the back 

 edge of the rostral plate ; vertebral plates three, one behind the other, 

 the middle largest, hinder triangular ; superciliary plates moderate ; 

 ears very small, nearly hid ? eyes small, with only rudimentary eye- 

 lids. Body elongate, subcylindrical, covered with uniform small im- 

 bricate scales ; feet four, far apart, the front ones rudimentary, short, 

 small, conical, undivided, ending in a simple claw, hinder small, weak, 

 with a distinct knee, and ending in two very unequal clawed toes ; 

 tail elongate, cylindrical, tapering. 



Rhodona punctata. Grey brown, back with rows of small black 

 spots, those of the middle of the back and tail largest ; labial scales 

 brown-edged. Body four, tail three inches. Eyes small.

The genus Rhodona appears to form a distinct family, (characterized 

 by the form of the rostral shield, the position of the nostrils, and the

 Probably the genus Lerista of Bell may belong to the same group, 

 but the form and number of the head shields of that genus has not 

 been described.
