URING some excavations which have lately been carried on by 
Mr. J. J. Colman, M.P., at Corton Cliff, Suffolk, a number of 
Mammalian teeth were dug out of the ‘“ Forest Bed,” and these 
specimens, at the suggestion of Mr. James Reeve, of the Norwich 
Museum, Mr. Colman has very courteously allowed to be sent to me 
for examination and description. 
A few teeth of Rhinoceros Etruscus and of Cervus accompanied the 
series of four upper teeth of Hyena which form the subject of the 
present communication (see Plate X.). 
Although the remains of Bears have been so frequently met with 
in the Hast Anglian “Forest Bed,” yet indications of other large 
Jand-carnivora have only rarely occurred; and as far as ] am aware, 
the following are all the specimens known from deposits of this age, 
namely,—the Machairodus tooth in Mr. Savin’s collection; the 
distal end of a fibula closely resembling that of a Tiger, in the 
Jermyn Street Museum; the portion of a feline (?) humerus found 
by Miss Lucy Martineaux; the piece of a Glutton’s jaw in Mr. R. 
Fitch’s possession; a fragment of a Fox’s jaw in the British 
Museum ; a doubtful humerus of Wolf in the King collection, and a 
piece of a Marten’s jaw in the Jermyn Street Museum. These being 
all the remains of carnivora known from the “Forest Bed,” the 
series of teeth obtained by Mr. J. J. Colman are therefore a great 
acquisition, as they enable us to record the occurrence of another 
interesting genus and species in these deposits. 
These teeth include a left upper canine, and the second, third and 
fourth upper premolars of the right side; they are of a very dark 
colour, the enamel being jet black and highly polished. The enamel 
of all the crowns, especially of premolar No. 5, shows vermiform 
granular wrinkles. The teeth are in a very perfect state of preser- 
vation, but the points of all the cusps have been worn down to 
flattened surfaces, as is usual with Hyzena’s teeth that have been in 
use for some time. The greatest length of the canine is 61 milli- 
métres. Seen from the front, the fang is straight; but the crown is
