Cancer tetragonon

Herbst (1790)

Cancer tetragonon (Herbst 1790) image
This drawing is from Herbst (1790). It is the image accompanying the type description of Uca tetragonon. This species was, unusually for fiddler crabs, described from a female specimen (which at the time they did not realize were different than males, so no association was made between this specimen and the names associated with fiddlers).
