the ends of the occipital ridge ; thirteen pairs of ribs. 1. B. taurus : 
2. B. gawf'us : 3. B. gayal : 4. B. hanteng. — h. Bisons ; forehead broader 
than high, arched ; orbits projecting ; horns under the top of the fore- 
head ; more than thirteen pairs of ribs. 5. B. bison (1’ Aurochs) ; 6. B.

hubalus : 9. L^Arni d comes en croissant : 10. L’Arni geant : 11. B. 
caffer: 12. B. hrachyceros. The latter is described according to the 
same living individual from which Gray had defined his species, but, 
from growth, it has undergone considerable modification in some of its 
marks. 
Boulin looks on the Gaur, Gayal, and Banteng, as three difierent 
species ; and from the marks which he gives of their skulls, this seems to 
be indeed the case. With respect to the Gaur and Banteng, from the 
plates of their skulls (see our Archiv. v. tab. 9, for the former, and the 
Nederl. Verh. n. 7, for the latter), there cannot be a doubt but that they 
are different species ; as to the Gayal, there is stiU a difference of opinion. 
Whilst Boulin places it as a peculiar species, Delessert, on the contrary, 
asserts, that the wM oxen killed by him in the south of India, were the 
same with the Gayal {B. frontalis s. sylhetanus), as well as the Gaur; 
he refers at least for the latter to Hodgson’s description; so that it 
cannot remain doubtful, that at least those wild oxen of this division, 
extending through anterior India, from Cape Comorin to Nepal, belong 
to the Bos gaiirus, whilst the Bos sylhetanus of Sylhet and further 
India must be a different species from it. On this point S. MiiUer and 
Schlegel will, perhaps, soon furnish us with the necessary information. 
What Boulin has communicated on the Bison is the least satisfactory. 
His knowledge amounts to what Cuvier said of them, and he has made 
no mention of what has since been published by Bojanus, Jarocki, 
Brincken, Baer, Pusch, and the reporter, upon this subject. The dis- 
tinctions formerly given by the reporter between the Bison of the New 
and Old World, have since been confirmed by the sight of three beauti- 
ful Lithuanian specimens set up in Berlin. Their whole body is thickly 
haired, particularly on the fore part, without, however, any remarkable 
prolongation of the hair on the sides of the neck ; whilst, in the American 
Bison, the shoulders, neck, and head, are covered with thick curly felt, 
a foot long on the occiput. In the Lithuanian specimens, also, the ruffs 
at the posterior margin of the metacarpus, so remarkably well defined 
in the American Bison, are wanting. 
Blyth has given some information about two species of Wild Ox, said 
to be from the north-west of Africa. It is certainly not sufficient to fix 
the species (perhaps not even the genus), but still will give an impulse 
to further investigation. Of the one, a specimen was from the central 
region of Mount Atlas, and for some months lived at Tangiers ; its
