 ata of Daudin. It belongs to the genus Scincus, and cor- 

 responds with the description of S. S-lineata, It may be 

 useful to observe, that when the tail of this species has 

 been broken off and reproduced, the recent portion is of a 

 fine blue colour, verging on ultramarine. This alteration 

 in the colour of the tail, which I have traced through its 

 different states of regeneration, gives to the animal a dif-

 identity. Daudin mentions a variety with a blue tail, 

 which is doubtless the same. The blue tail of Catesby, 

 Daubenton, Lacepede, Sec. which is the Lacerta fasciata
