mentions on the same page a second specimen under the name Cervus 
guineensis. This, as Sir Victor Brooke has shown, was evidently quite a 
different animal—probably a young of some small species of Cephalophus. 
Nevertheless, in the 10th edition of the ‘Systema Nature,’ published in 
1758, Linneus, regardless of the name Capra perpusilla given in former 
publications, now attributes to the same species the new name Capra pygmea, 
and also founds another species, ‘‘ Cervus guineensis,” on the Cervus griseus 
subtus nigricans of the ‘‘ Museum Adolphi Frederici.” In the 12th edition 
of the ‘Systema’ (1766) these two species are united under the title Moschus 
pygmeus. It is, however, manifest from the diagnosis, and from his reference

to Seba’s plate, that the “Royal Antelope” was the principal object in 
Linneus’s mind when he founded his Capra pygmea. There is also little 
doubt, as Sir Victor Brooke has shown, that the young specimen of the 
Royal Antelope which ultimately passed from Seba’s Museum to Leyden 
was the original of Seba’s figure, plate 43. fig. 3, and that the specimen 
of the same species that went to the Stockholm Museum was the original of 
Seba’s figure 1 of plate 43. Under these circumstances we can have no 
hesitation in following Sir Victor Brooke, and adopting the term pygmaeus of 
Linneus as being the correct specific name of this Antelope. For its generic 
name we must use the term Neotragus, proposed by Hamilton Smith in 1827,
