A nearly complete skeleton of an erycine boid is described from the Ypresian-Lutetian (early-middle Eocene) site of Messel, Germany, for which we propose the name Rageryx schmidi n. gen., n. sp. The animal had a total length of c. 52 cm, with c. 258 vertebrae. In skull proportions it is similar to ungaliophiine boids, especially Ungaliophis, and to Tropidophis. The proportions and distinctive accessory processes of the distal caudal vertebrae that are common to all living erycine boids are present in the specimen, although the processes are not as elaborate as in many extant species. The premaxilla was not protruded to form a wedge-shaped snout, and the nasofrontal joint does not appear to show any special buttressing, unlike in many burrow...
