Skull roof of (A) Eopehbates grandis, PU 16441, X ; (B) E. guthriei, MCZ 3493, X 3. Dashed line restoration; dotted line = broken bone outline. Mlynarski referred to Eopehbates sp. material from the Pliocene of Poland. The specimens consist only of sacra having separate urostyles. Other fused sacra and urostyles and characteristic skull elements he referred to Pelobates of. fuscus. Since, however, Eopelobates is otherwise un- known later than middle Miocene, and since Pelobates cultripes often has partially or completely separated urostyles, it seems unlikely that Eopelobates is represented in the Polish material, at least in the absence of characteristic skull elements. These elements may be referable to Miopelobates (see below). Since the salamander Andrias is now known to occur in the European Pliocene (Westphal, 1967) there is no ap- parent reason why Eopelobates might not also have persisted, but at present there is insufficient reason to confirm its extension beyond the middle Miocene. Description of New Material of Eopelobates Eopelobates guthriei, n. sp. Type: MCZ 3493, nearly complete skull and associated fragmentary scapula. Diagnosis: Differs from other species of Eopelobates in having a narrow tympanic process of the squamosal combined with a triple emargination of the frontoparietal margins and a relatively short skull. Etymology: Patronym for Dr. Daniel Guthrie, who collected the unique speci- men in 1962. Locality: NE 1/4, SE 1/4, Sect. 16, T 39 N, R 90 W, Fremont County, Wyoming. Horizon: Upper part of the Lysite mem- ber, Wind River Formation. Age: Early Eocene (Lysitean, late Sparnacian equivalent). Preservation: Only the skull, portions of the prearticular region of the jaws, and an associated fragment of left scapula are present (Fig. 14). The slightly crushed skull is well preserved on the right side, but on the left t
