40950. The greater portion of the left ramus of the mandible, con- 

 (Fig.) 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 2 . This specimen 

 was described by Falconer in a manuscript note, which 

 has been published in his ' Palseontological Memoirs/ 

 vol. ii. p. 462, under the name of " Hyaenoid 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. lupus, and has a 

 wider talon than in L. 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. lupus 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 j^T4 seems to indicate 

 affinity with some of the more generalized species of 

 Hycena, like H. macrostoma.
