Family CERVIDiE. 
Genus CERVUS. 
Subgenus MEGACEROS Owen. 
C. [Meoaceros] hibernicus (Owen). — This species seems 
to have had some of the characters of the elk, the reindeer, 
and the fallow deer, combined with others peculiar to itself. It 
differed from the existing elk, to which however it is closely allied, 
by its immense size, and the possession of a brow antler which is 
not present in Cervus dices. From Cervus dama , or the fallow 
deer, it also differed, because in the fallow deer all the branches 
above the bez-antler are sent off from the posterior margin and end 
of the palm, while in Megaceros they are all with one exception 
sent off from the anterior and terminal margin. 
The species is found in the forest-bed, and dredged from post- 
glacial deposits' along the coast. 
Subgenus ENCLADOCEROS Falconer. 
C. [Encladoceros] sedgwickii (Gunn). — Dr. Falconer who 
founded this snbgenus, says in his ‘ Palseontograpliical Memoirs,’ 
vol. ii, p. 473, the chief characteristics are as follows: — “Horns 
pedunculate without brow or bez-antlers ; beam and compound 
antlers compressed, the latter thrown off forwards and terminating 
without palmation in long tynes.” 
Of the species Cervus sedgwickii, he goes on to say, “ Horns 
very ample, indicating a large species. Bar prominent without 
obliquity. Beam cylindrical and straight at the base, compressed 
upwards, giving from its anterior margin three sub-equidistant 
antlers which, from the summit downwards, are successively hi-, 
tri-, and quadri-furcate. Tynes long, straight, and conical, diverg- 
ing in the same vertical plane. A single elongated tyne or forkC?) 
terminating the beam.” 
In a letter I received from Professor Boyd Dawkins, he informs 
me that Cervus sedgwickii is undoubtedly the same as the Cervus 
martialis of Gervais. Cervus martialis possessed sub-compressed 
ramified antlers, slightly expanding at the base of the terminal 
divisions ; the brow tyne was also absent. In this respect Cervus 
martialis agrees very closely with Cervus sedgwickii; and from the 
different remains of Cervus martialis which have come under my
