Show 210 MR. F. E. BEDDARD ON [Mar. 3, is an egg of a Struthio lias been proved by von Nathusius. Its geological age cannot certainly be determined because it was found floating in a river. Brandt supposes that it had been embedded in the bottom ot the river and had been worked out by the water. I lie age of the strata forming the bed of that river is supposed to be that of the strata in which von Nordmann1 discovered the mammalian remains in 8 . Russia (environs of Odessa), and therefore that of the breccia of Pikermi; but it may be much younger, because Nordmann3 does not separate the Tertiary from the Pleistocene. In the paper above mentioned, he attributes the bone-beds of S. Russia to the " offenen Diluvium," and says that it has the same geological age as the bone-beds of the Yal d'Arno. Therefore we have no evidence of the exact geological time during which a Struthio lived in South Russia, and the egg is in consequence of little importance in regard to this question. Moreover, it seems to me more than doubtful to assign this egg to the modern^ Ostrich, and " very likely to the species occurring at Samos, as is done in Nicholson and Lydekker's ‘ Manual of Palaeontology ' (p. 1228). 5. On a new Genus and two new Species of Earthworms of the Family Eudrilidce, with some Notes upon other African Oligochaeta. B y F r a n k E. B e d d a r d , M.A., F.R.S., F.Z.S. [Received March 3, 1903.] (Text-figures 35-38.) The fiist set of specimens referred to in the following descriptions form a pait of the collection m the British M^useum; I am greatly indebted to the kindness of the Director for allowing me the opportunity of examining them. They belong to two species, both of which are undescribed. The first is a third species of the genus Stuhlmannia, which I call Stuhlmannia michaelseni, n. sp. I have examined so many individuals of this form of Stuhlmannia, and the agreement between them is so close, that I have no hesitation in regarding it as a distinct species, which I name after the founder of the genus, Dr. Michaelsen3. The worms were collected by Mr. S. L. Hinde in the Mt. Kenya district. There were thirty mature examples. The general appearance and proportions of this new species are quite the same as in S. variabilis. The length reaches 100 mm and the diameter 2-2'5 mm. The colour is a yellowish grey; the clitellum is greyer. & I gordmann, in ‘ Jubilseum semisaeculare Fischeri de Waldheim/ Moscou, 1847 ; .Nordmann, Palaontologie Siid-Russlands, 1858. 3 JB.
