EL. T. Newton— Vertebrata of the Forest-bed. 147 
The second specimen is from the “ Forest Bed” of Trimingham ; 
it consists of a pair of horn-cores from which the skull has been 
broken away ; they are slender and more curved than in most fossil 
examples of the Bison; but a portion of the skull, still attached to 
one of the cores, shows that they were placed a little forward from 
the back, and consequently must be referred to Bison. 
The third specimen is a fine large horn-core from the “Forest 
Bed” of Overstrand. There is not sufficient of the skull left to 
show its characteristic extension behind the horn-core; but it is 
evidently that of a Bison; being very thick and compressed at its 
base, where its circumference is 340 mm., and comparatively short, 
its length, measured along the convex surface, being 390 mm. 
There can be no question as to the reference of these specimens 
to the genus Bison, and as there is no good reason for supposing 
that they are other than the well-known Pleistocene species, they 
are placed with Bison priscus, or rather, to use the corrected nomen- 
clature, Bison bonasus, var. priscus. 
Having then undoubted evidence of the occurrence of Bison in the 
Cromer ‘Forest Bed,” and as all the bovine specimens hitherto 
found may belong to that genus. it will be necessary to remove 
the genus Bos from the lists of “‘ Forest Bed” mammals, until there 
is definite proof that both forms existed. 
Phoca (Hrignathus) barbata, Fabricius (Bearded Seal). Pl. V. 
Figs. 2, 2a. 
The genus Phoca has already been recorded from the Cromer 
“ Forest Bed” (Survey Memoir, p. 29); but the specimens known 
did not allow of specific identification, although it was thought they 
might belong to Phoca vitulina. Mr. Savin now possesses a very fine 
characteristic humerus of a large Seal from Overstrand, near Cromer. 
The deltoid crest as well as the proximal and distal tuberosities 
are somewhat broken, so much of the latter being lost that only a 
trace of the supra-condylar foramen remains. In spite of these 
defects, however, there can be no question as to the form of the 
bone. The deltoid crest is strongly developed and extends half-way 
down the bone, its outer side having a well-marked depression. 
The shaft is laterally compressed; the upper part of the back is 
rounded, but lower down there is a ridge, which passing outwards 
is continuous with the outer or supinator ridge. A smooth space on 
the inner side a little above the distal articulation shows the position 
of the supra-condylar foramen. The principal measurements of the 
bone are :—greatest length, 143 mm. (5:55 inches); short diameter 
of middle of shaft, 19 mm.; length of deltoid crest, 76 mm. ; diameter 
of head, 80 mm. 
On comparing this humerus with those of the Seals in the Royal 
College of Surgeons and in the British Museum, I find it differs in 
certain important points from all but one of them, namely, Phoca 
barbata, and with this it agrees so exactly in every particular, except 
in being a trifle smaller, that I have no hesitation in referring the 
fossil to the same species.
