Abstract
IN the family Goodeidae, unlike the other viviparous Cyprinodontiformes, the male anal fin is not modified into a gonopodium. Three years ago, we discovered in Skiffia lermae (Goodeidae) a muscular structure which seems to serve as a reproductive organ and which we called a “pseudo-penis”1,2. This structure consists of a substantial muscular mass situated just behind the visceral cavity; it surrounds (a) a highly dilated vas deferens, the internal surface of which presents numerous villosities, and (b) a urinary canal.
