Prof. Busk subsequently recognized the remains of the Glutton 
among the bones found by the Rev. J. M. Mello in the Creswell 
Crag Caves (Q.J.G.S. vol. xxxi. 1875, p. 687). 
The presence of the remains of this animal in the German Caves 
had been made known by Dr. Goldfuss in 1818 (Nova Acta, tom. ix. 
p- 311). Dr. Schmerling recorded its presence in Belgium in 1833 
(Oss. Foss. Liége, p. 167), and M. Gervais noticed its occurrence in 
France in the Cave of Fouvent (Haute Sadne) in 1867 (Zool. et 
Paléont. General, p. 252). The specimen figured by Dr. Kaup as 
Gulo diaphorus (Oss. Foss. 1832) most certainly belongs to another 
genus. 
All the fossil remains of the Glutton hitherto known, both in 
Britain and on the Continent, have been obtained, as above mentioned, 
from Cave deposits, and are consequently of somewhat uncertain age ; 
the finding of the specimen which forms the subject of this com- 
munication is therefore of especial interest, as it shows that the 
animal lived in Britain during the time when some of the beds 
forming the “Forest Bed Series” were being deposited, and con- 
sequently it carries back the advent of the Glutton in Britain into 
what are usually regarded as pre-glacial times. 
This “ Forest Bed” specimen, as already intimated, is the property 
of Mr. R. Fitch, and is preserved in his magnificent collection at 
Norwich. It consists of about two inches of the left ramus of the 
lower jaw, with the first true molar, or sectorial tooth, in place, 
together with the hinder half of the fourth pre-molar. Part of the 
alveolus for the second true molar is likewise preserved, and this is 
fortunate, for the Plas Heaton specimen is defective in this latter 
particular, the jaw being broken away behind the first true molar. 
The entire surface of the “Forest Bed” specimen presents that 
peculiar grooved and channelled appearance not uncommon among 
fossils from these beds. The Plas Heaton specimen is shown by 
Prof. Boyd Dawkins to be larger than the recent one in the British 
Museum, with which he compared it; on the other hand, the lower 
jaw now under consideration is much smaller, and corresponds more 
nearly in size with a Glutton’s jaw preserved in the Museum of the 
Royal College of Surgeons, and, with the exception of this slight 
difference of size, the two are so precisely alike that the description 
of the fossil given below would answer equally well, in every 
particular, for the recent specimen. It is through the kindness of 
Prof. Flower that I am enabled to give figures of this recent jaw for 
comparison with the fossil one (PI. XV. Figs. 4-6). 
The outer surface, below and behind the first true molar, becomes 
concave as the jaw curves outwards to the prominent angular portion, 
and the depression for the masseter muscle is deep. The inner 
surface is convex, especially towards the alveolar border. The teeth 
are implanted towards the outer side, a peculiarity of the Glutton’s 
jaw pointed out by Professor Boyd Dawkins, and consequently the 
crowns overhang the outer surface. The large sectorial tooth, m. 1, 
has its two cusps so nearly equal in size that the trifling superiority 
of the posterior one is scarcely perceptible. These cusps are
