i^PINE-TAILED LIZARD. 217- 



plait, as in the Ameiva: the whole skin also 

 about the neck, throat, and beginning of the 

 sides, is, in this specimen at least, remarkably lax, 

 and it is probable that in the living animal the 

 skin beneath the throat may have a kind of 

 pouched appearance, though entirely without any 

 middle carina on that part : the other parts of the 

 body, both above and below, are covered with 

 very small scales ; of which, however, those of 

 the under parts are rather larger than those of the 

 upper. From the beginning of the neck to the 

 origin of the tail runs a series of short denticula- 

 tions, forming a serrated crest of very slight ele- 

 vation : the tail is very long, and strongly marked 

 into numerous verticilli or rings, composed of 

 very long and very strongly carinated scales; each 

 terminating in a lengthened point and thus 

 causing a spiny appearance throughout the whole 

 length of that part : the feet are all pentadacty- 

 lous, and the toes rather long ; especially those 

 of the hind feet : the claws strong and sharp. The 

 colour of this species on the upper parts is glau- 

 cous, variegated with a few small and somewhat 

 indistinct clouds and marblings of a whitish cast : 

 the tail and under parts are of a pale or yellowish 

 white colour. 



This species seems much allied to the Quetzpaleo 

 of Seba, 1. p. 152. t. 97. f 4. which is generally 

 supposed to represent the Azurea of Linnaeus.
