Eliminating the two bovine quadrupeds and sheep now accepted 
as domesticated animals, the Elk or Moose and, indeed, the Hippo- 
potamus which I also exclude for reasons detailed in the sequel. 
It appears to me also that the Bears are reducible to apparently 
one species, so that the extinct mammals of Ireland, as far as I 
am enabled to find out are— : 
1. Ursus fossilis (Goldfuss), vel U. ferox, fossilis. - 
2. Canis lupus. 
3. Elephas primigenius. 
4, Equus caballus. 
5. Sus scrofa. 
6. Cervus megaceros. 
7. Cervus tarandus. 
The extinct Cetacean remains have not been critically examined, 
and beyond vertebra and fragments of crania and mandibles in 
marine deposits along the coasts, there are no data sufficient to 
furnish specific distinctions, nor are their stratagraphical relations 
known with accuracy. 
A striking feature of the lists of Irish Mammals, both recent 
and fossil, will be observed to be the remarkable small number of 
species as compared with England. A circumstance which can 
scarcely admit of any other interpretation than that Ireland was 
only partially united to Great Britain, or that the severance took 
place before the fauna of the latter had time to spread over the 
country, and it may be that the physical conditions were also 
inimical to certain species during the Lake Period when the shell 
marl was being deposited. Admitting that the surface deposits 
of Ireland and its hmestone caverns have not been so systemati- 
cally explored as in England, but even Scotland has produced more 
* Catalogue of the Mammalian Fossils which have been discovered in Ireland by 
R. H. Scott, F.R.S., ‘*Geological Magazine,” vol. vii. p. 413, Feral species of sheep and 
goats are stated by Professor Hull in his late book on the “ Physical Geology and 
Geography of Ireland” to have been found in the Island, Of this assertion there is no 
proof whatever beyond the rejectamenta of prehistoric, and possibly historic man met with 
in caves recently occupied.
