ihas yielded to Schlosser ^ an almost complete lower jaw, wliicli lie 

 identifies as being of the same species with the skull in the 

 Stuttgart Museum, and he even believes that both may belong to 

 the same specimen. While referring the reader to Schlosser's 

 description of the conformation of the lower premolars, canine, and 

 incisors, and to Osborn's figure (pi. ii, fig. 3) of the upper ante-molars, 

 I wish to recall the fact that from the conformation of the anterior 

 lower premolar of his Zeptodon grcecus, Gaudry had already rightly 

 concluded that the lower canine " a du etre en contact avec la 

 premiere premolaire et avoir une faible dimension." - This 

 conclusion has been fully borne out by Schlosser's discovery of the 

 Samos mandible. 



From what has been ascertained by these successive discoveries, 

 it is now satisfactorily established — (1) That the four fossils in Paris, 

 Stuttgart, Munich, and London belong to a single genus ; the name 

 Zeptodon being preoccupied, as was pointed out to me by Mr. 

 Lydekker, it will have to be known as Pliohyrax. (2) That the 

 mandible from Pikermi in the Paris Museum and the skull from 

 Samos in the British Museum are, moreover, the same species, 

 Pliohyrax grcecus (Gaudry). (3) The mandible at Munich and the 

 skull at Stuttgart, both from Samos, have been shown by Schlosser 

 to be the same species. 



Whether all four fossils are one and the same species, may 

 be decided when exact measurements of the Stuttgart skull are 

 available. M. 1 of the London and the same tooth of the Stuttgart 

 specimen are approximately of the same size ; but the skull of the 

 latter seems to be somewhat smaller. This may be due either to 

 individual or to sexual variation ; I have in my first note pointed 

 out, that the shape of the large incisors in the Stuttgart fossil 

 exhibits a greater agreement with the incisors of female Hyraces 

 than with those of male specimens.
