A portion of the right ramus of an Edaphodon mandible, from the pbosphatic beds near Cambridge, deposited by the late Prof. Sedgwick in the Museum of the Geological Society of London, was described in the year 1843 by Prof. Agassiz under the specific name of Sedgivickii. The fragmentary character of the specimen prevented any very detailed description being given, and, consequently there has been some difficulty in determining whether certain specimens which have been obtained subsequently ought to be referred to this species or not. Having carefully examined the original specimen, I have convinced myself of its specific identity with the specimens to be presently described as Edaphodon Sedgwickii. Great difficulty has been experienced in determining which of the maxillae and preniaxilke, found in the Cambridge phosphatic deposits, were to be referred to this species, for the different parts are so rarely found together; and even when said to have been found associated, the nature of these deposits, and especially the manner in which the fossils are mostly obtained from them (i.e., after working in the coprolite mills) renders it extremely doubtful whether bones so found belong to the same individual. Of course the same may be said of all the species found in thee deposits, and it is on...
