serve that this author names on his plates what we call Phoca an- 
nellata P. hispida, and what we call P. granlandica P. annellata. 
Believing it to be desirable that the Seals, which are so difficult to 
distinguish by their external characters, should be divided into small 
sections or subgenera by organic characters, I propose to divide 
the tribe of Phocina, as defined in my Monograph (see Cat. Seals 
in the British Museum, p. 20), thus :— 
. Branches of lower jaw diverging ; the lower edge of the lower jaw 
rounded, simple ; palate angularly arched behind ; angle of lower 
jaw blunt, sloping behind. CaLiLocrpHauus. C. vitulinus. 
2. Branches of lower jaw diverging ; lower edge of lower jaw di- 
lated on the inner side. 
* Palate angularly notched behind ; angle of tower jaw blunt, 
sloping behind. Pacomys. P. fetidus. P.? nummularis. 
** Palate truncated behind; angle of lower jaw acute, erect 
behind, with a notch above the basal tubercle. Pago- 
PHILUS. LP. gren/andicus. 
3. Branches of lower jaw arched on the side and wide apart ; lower 
edge produced on the inner side behind the symphysis ; palate 
arched. 
* Tubercle on inner edge of front part of lower jaw elongate, 
sharp-edged ; teeth moderate ; angle of lower jaw simple, 
with a distinet notch above it. Hanicyon. H. Richardii. 
** Tubercle on inner edge of front part of lower jaw blunt, 
rugulose ; teeth small; angle of lower jaw with a rounded 
lobe on inner side above the basal tubercle. PuHoca. P. 
barbata. 
Pacomys ? NUMMULARIS. 
The lower jaws short and broad ; the grinders thick, with a broad 
thick central lube, and nearly side by side (in the skulls of the young 
animals).

This species is only known from some skins and three fragments 
of skulls in the Leyden Museum. 
My excellent friend Professor Schlegel, the energetic Curator of 
the Leyden Museum, has most kindly sent to me for examination 
and comparison the fragments of skulls above referred to: they 
consist of the face-bone and the lower j jaws of three specimens; the 
most perfect specimen has part of the orbit and the upper part of 
the brain-case attached to it. ‘They are all from very young speci- 
mens, of nearly the same age; and, unfortunately, the most perfect 
one is without the hinder “portion of the palate, so that I cannot 
make sure that it has the same form of the palatine margin that is 
found in Pagomys; but the part of the side of the palate that is 
present, when compared with the same part in Pagomys, leads one 
to think it most likely to be of the same form as in that genus.
