Thank you for the elaboration, I very much appreciate it, very interesting about the signage, too, and the thought Bronx once had multiple rare lorisoids!
The slender loris you can find photos online of, such as on ZooInstitutes: Loris tardigradus / Slender loris in Bronx zoo
Memphis held this species more recently, though they may have died out within the last few years. I believe Minnesota also once held them.
