12. Lepus cuniculus (Linn.). With regard to this animal, we 
think that, without more exact evidence than we have as yet met 
with, considerable doubt must exist as to its having been really 
contemporaneous with the Mammoth in these islands. Professor 
Owen, in the ‘ British Fossil Mammals,’ merely refers to several in- 
stances of the occurrence of its bones in caves, without any further 
notice of their state or position in the deposit ; and the same remark 
may be made with regard to the notice of the animal by Dr. Buck- 
land, in ‘ Reliquie Diluviane,’ p. 19. The burrowing habits of the 
animal are such that, unless the bones are found imbedded in such 
a position, and in such condition, that there cannot be any reason- 
able doubt of their date, we must be most cautious as to admitting 
the rabbit as an undoubted member of the Mammoth-fauna. We 
have examined a very large number of bones from different British 
caves, but have never found those of the rabbit in breccia or in old 
stalagmite—in fact, in anything but the soft cave earth, and that 
extremely rarely. Now, in the more recent deposits in the caves, 7.¢. 
in those which contain domestic animals, the rabbit is one of the 
most abundant fossils; and when its known fecundity is taken into 
account, it is extremely difficult to imagine why, if it coexisted at 
all with the Mammoth, its bones are not more abundant in the de- 
posits which contain that animal. Yet with the evidence we have 
from Wookey Hyna-den, from Hutton, and, in a single instance, 
from Kent’s Hole, itis necessary for us to insert provisionally, as it 
were, the rabbit as one of the rarest members: of the Mammoth- 
fauna; for from each of the above it occurs in our collections, 
although very rarely, in apparently the same state as the remains of 
extinct animals. Still, without actual examination and notes taken 
at the time, we are without evidence as to the possibility or other- 
wise of the animal having burrowed into the see in which its 
bones occurred. 
13. Genus Spermophilus.—The insertion of Suanmophitte citillus 
in a list of the Pleistocene Mammalia, published some time since by 
Mr. Boyd Dawkins. and myself, was founded on a mistake which it 
is necessary to explain :-— 
A late curator of the Taunton Museum altered the label on one 
of the specimens of Spermophilus erythrogonoides, which had been 
described by Dr. Falconer, to S. citillus. We, supposing that he had 
the authority of Dr. Falconer for the determination, placed the species 
in our lists without further examination. When, however, we came 
to examine the collection, specimen by specimen, we at once disco- 
vered our error ; and on the publication of Dr. Falconer’s posthumous 
Memoirs, we found that Dr. Falconer had attributed both jaws to 
S. erythrogonoides. A third jaw, among bones from Bleadon cave, 
which had belonged to Mr. Williams, has since been discovered. 
14, Genus Cricetus.—The last species we shall notice is Cricetus 
(Mus) songarus (Pallas). It is known that Mr. Willams disco- 
vered in the Hutton cave what he considered to be the bones (in- 
cluding parts of the skulls) of mice. Nosuch occur in his collection; 
but we find that which he might have easily mistaken for them—the
