Dorsal and ventral views of the holotype of Para- rhadinaea melanogaster Boetlger (SMF 17885). Total length = 239 mm. Approximately tophis subcaudalis are identical in config- uration to that of the t)^e of P. melano- gaster. MNHN 1982-1220 and SMNS 4235 have, respectively, 12 + 2 and 14 + 2 maxillary teeth on the right side (the left maxilla of SMNS 4235 is missing). As in SMF 17885 the maxillary teeth in both specimens gradually increase in size pos- teriorly, a diastema is absent, and the fangs are ungrooved and slightly larger than the immediatelv preceding teeth. In both MNHN 1982-1220 and SMNS 4235 the tooth immediately preceding the first fang is approximately two-thirds the length of the fangs (three quarters of the length in SMF 17885). All maxillary teeth are hinged except for the fangs (and perhaps the last tooth immediatelv preceding the fangs in MNHN 1982-1220). SMNS 4235 has 14 dentary teeth on each side. The anterior dentary teeth are small and hinged. Teeth 7-9 are abruptly enlarged (especially teeth 8 and 9), and these are followed by five large, widely spaced teeth similar to those of SMF 17885 (Fig. 7); narrow gaps separate the first nine dentary teeth. Apart from the first six teeth, none of the dentary teeth are hinged. In MNHN 1982-1220 the an- terior six dentary teeth are small and hinged, and these are followed by five or more enlarged, firmly ankylosed, widely spaced teeth (the posterior dentary teeth of this specimen were not thoroughly in- vestigated). A Comparison of the Known Specimens of Pararhadinaea melanogaster Boettger The three known specimens of Parar- hadinaea melanogaster have never been directly compared and some comment on their characters seems warranted. The provenance of the type of Rhahdotophis subcaudalis is unspecific (type locality: "Madagascar"), whereas th
