Species of crayfish
Procambarus angustatus was a species of crayfish in the family Cambaridae. It was only known from the type specimen, described by John Lawrence LeConte in 1856. He reported that it "lives in lesser Georgia, in the rivulets of pure water which flow between little sand hills".[1] It was endemic to the U. S. state of Georgia, but is now believed to be extinct.[1]
