OBSERV. We agree with Gray in restoring the genus Teius, of Mer- 

 rem, although the species we refer to it here, is not placed the first on 

 the list by the author just mentioned. The name of Monitor is very 

 objectionable, it having been applied indiscriminately to species be- 

 longing to the Varanid family as well as to Lacertians. That of Sal- 

 vator might have been adopted with great propriety, had there not 

 been another claiming priority.
