are strong and numerous, while in Psaris they are scarcely per- 

 ceptible. The tarsi though somewhat longer than those of Psaris 

 are ia a slight degree weaker, while the toes are longer and 

 stronger. The lateral scales of the tarsi are square and far asun- 

 der, while in Psaris they are rounded and numerous. The hinder 

 scales also are less rounded, less close, and less conspicuous than 

 in the latter genus. 



I have named this species in honour of my friend. Colonel 

 Cunninghame, of Rio Janeiro ; happy in having it in my power 

 to make some slight return for the numerous and liberal attentions 

 I have received from him, and to offer this public acknowledge- 

 ment of the value in which I hold his friendship.
