The flat skins of this Antelope, so remarkable for their transverse black bands, first attracted the attention of naturalists in 1832, when they were brought before the Committee of Science and Correspondence of the Zoological Society of London by Mr. E. T. Bennett, then Secretary of the Society. Mr. Bennett considered them as belonging “not improbably” to some species of Antelope, to which, however, he did not venture to give a name. They were supposed by Gould (then the Zoological Society’s taxidermist), who had obtained them, to have been received from Algoa Bay; but there is no doubt that this was an error, and that these flat skins, some of which are even now occasionally brought to this country, are from Sierra Leone and the adjoining districts of Western Africa. For some years this subject appears to have slept, but was revived in 1836 by Mr. Ogilby, who, in the course of some remarks upon the preserved specimens of Antelopes in the Zoological Society’s Museum, took the opportunity of assuring his hearers that the skins described by Mr. Bennett belonged to a “real Antelope” and that he hoped shortly to “have an opportunity of describing it in detail under the name of _Antelope doria_.” Some two years later the late Dr. Gray proposed the name “_Antilope zebra_” for the same animal, based upon a skin received by the British Museum from Sierra Leone. Gray recognized it as being evidently the same as that previously described by Bennett, and gave no reason for proposing to alter its name. About the same time similar imperfect flat skins attracted the attention of M. Robert, of Paris, who shortly described them in a communication to the ‘Echo du Monde Savant’ of 1836 under the name _Antilope zebrata_. But there is no doubt, we think, that “_doria_” was the first published specific appellation of this Antelope, and ought to be adopted. “Doria” is stated by Gray (Cat. Ung. p. 129) to have been the Christian name of Mr. Ogilby’s wife. In his ‘List of Specimens of Mammals in the British Museum,’ published in 1843, Gray assigned this species to the genus _Cephalophorus_, i.e. _Cephalophus_. In his subsequent Catalogues he transferred it to the genus _Damalis_ (i.e. _Damaliscus_),“on account of the dark mark on the outside of the limb.” From the flat skins in the British Museum and the Zoological Society’s collection, Fraser, in 1849, gave a partly imaginative figure of this Antelope in his ‘Zoologia Typica.’ It was more than 50 years after the imperfect description of this problematical Antelope from the flat skins before science obtained correct information as to its proper characters and position in the system.
