CARNIVORA, 
Lycaon anglicus, Lydekker’. 
Hab. England. 
40950. The greater portion of the left ramus of the mandible, con- 
(Arig.) 
taining the four premolars and the carnassial, with the 
alveoli of the incisors, canine, and m. 2; from the cave of 
Spritsail-Tor, Gower, Glamorganshire*. This specimen 
was described by Falconer in a manuscript note, which 
has been published in his ‘ Paleontological Memoirs,’ 
vol. ii. p. 462, under the name of ‘“ Hyznoid Wolf,” and 
full measurements are given. Two small-size figures are 
given in plate xxxvi. figs. 1, 2 of the same volume. The 
length of the cheek-teeth is somewhat in excess of that of 
average-sized specimens of Canis lupus, and is very con- 
siderably greater than in Lycaon pictus. The carnassial 
corresponds very closely with that of C. lwpus,and has a 
wider talon than in ZL. pictus: this tooth conclusively 
proves the canoid nature of the specimen. The fourth 
premolar is a very remarkable tooth, being relatively 
much wider than the corresponding tooth of C. lwpus or 
L. pictus. It agrees with the latter, and differs from the 
former (and that of all species of Canis) by the presence 
of a distinct anterior talon. The second and third pre- 
molars are also relatively wider than in Canis lupus or 
Lycaon pictus, and have a trace of a minute anterior 
talon, which is generally more or less distinctly developed 
in the latter. The first premolar does not present any 
noteworthy characters. 
There is no question but that the specimen is specifically 
distinct both from Canis lupus and Lycaon pictus. The 
form of the fourth premolar being nearer to the corre- 
sponding tooth of the latter than to that of the former, it 
has appeared advisable to refer the specimen provisionally 
to the genus Lycaon, with the specific name of anglicus. 
The relatively great width of pm.4 seems to indicate 
affinity with some of the more generalized species of 
Hyena, like H. macrostoma.
