Part and counterpart of a well-preserved specimen of Gondekia lancifer (Reimann, 1945a), and a well-preserved specimen of Pseudohydnoceras erraticum Reimann, 1935, are described from the Wanakah Member of the Middle Devonian, Givetian, Ludlowville Formation, of western New York State. The specimen of Gondekia is only the second articulated specimen known and is more complete than the holotype. It has an intact skeleton of felted sexiradiates of three orders of spicules; the largest has rays approximately 2 mm long. The specimen of Pseudohydnoceras has preserved hexactine-based spicules in a dictyid skeleton, described for the species for the first time.
