120 PROF. W. BOYD DAWKINS OX A PLIOCENE [May I9O3, 



the first right upper molar, exhibits the characters of the Rhinoceros 

 etruscus of Falconer, which I defined in my paper brought before 

 the Society in 1868. 1 It is so like the corresponding part of a left 

 upper molar from the Val d'Arno in the Natural History Museum, 

 figured in the Quarterly Journal, vol. xxiv (1868) pi. viii, fig. 3 b, 

 that it is unnecessary to reproduce it. 



The second fragment consists of a crown of a lower true molar, 

 so worn that it has lost its distinctive characters, as is the case 

 indeed with many remains of Rhinoceros from the Crag which are, 

 as a rule, ascribed to the Miocene Rh. Schleiermacheri of Kaup. 

 It may, with high probability, be referred to the same species as the 

 upper molar. 



(f) Equus Stenonis, Nesti. 



The horse is represented by three upper molars and one lower. 

 The most perfect of these (PI. XII, figs. 1-3) has all the characters 

 which have been shown by Dr. Boule to mark off Equus Stenonis from 

 E. caballus. They consist of the small section of the columella (a) 

 in the grinding-surf'ace (PI. XII, fig. 1), as compared with its large 

 extent in Equus caballus (PI. XII, fig. 4 ) from the Creswell caves, 

 and in the narrowness and sharp definition of the two ridges or 

 costoe (PI. XII, figs. 2 & 3) traversing the external lamina of the 

 tooth, when contrasted with the broadness and flatness, and some- 

 times the grooving of the corresponding portion in the latter species. 

 On the inside of the tooth the columella is narrower than in 

 E. caballus (PI. XII, figs. 5 & 6). These points of difference are 

 comparatively small, but they are observed in the equine teeth found 

 in the Pliocene of Auvergne and of the Yal d'Arno, as well as in 

 the teeth assigned to this species by Mr. E. T. Newton 2 from the 

 Forest-Bed of Norfolk. 



A lower true molar (m 3) and two fragments of upper molars 

 present no points worthy of remark. They probably belong to the 

 same species. Dr. Boule 3 recognizes intermediate forms in the 

 Upper Pliocene or early Pleistocene strata of Solilhac. His view 

 that the Pliocene Equus Stenonis is the ancestor of the Pleistocene 

 E. caballus is probably true. 



(g) Cervus etueriarum (?) Croizet & Jobert. 



The Cervidae are represented at Doveholes by numerous bones, all 

 more or less fragmentary, and therefore very difficult to determine 

 specifically. They belong, however, to one or other of the many 

 species of Pliocene deer, and agree more particularly with Cervus 

 etueriarum of Croizet & Jobert= C. peyrollensis of Bravard, from 



a Quart. Journ. Geol. Soc. vol. xxiv, p. 207.
