Eunectes deschauenseei is the third.
No such species of the two other you had listed where i was looking.
This is the species i found on this site though nobody has any write up to conclude the species.
Color isn't base reffered though just called a dark spotted/deschauenseei anaconda. It does say it resembles the notaeus.
