MAMMALIA. 



cauines when the mouth is closed. Both sets of teeth are finely preserved in 

 the specimen. The species is identical with Hyaina neogmi of Lund, and 

 Felis smilodon of Blaiuville. Some writers place it in the genus Drepanodon. 

 Cope includes the nine species found in the Old World in the genus Drepano- 

 don, Nesti, and the four American species, all Pliocene, in the genus Sviilo- 

 don, Lund. The original of this specimen, discovered in a bone cavern in 

 Brazil (Post-Pliocene), is in the Museum of the Garden of Plants, Paris.

Lower Jaw, left ramus (cast). In 

 Post-Tertiary times troops of gigauic Hy- 

 senas roamed over the whole continent of • 

 Europe, and especially in England, where 

 the caves were evidently tenanted by suc- 

 ces.sive generations. The floors of these caves were found, when finst opened, 

 to be strewed over, like a dog-kennel, with liundreds of teeth and splintered 

 bones, evidently the remains of prey dragged in by these ferocious carnivores. 

 The Kirkdale cavern contained, it is said, remains of some three hundred 

 Hyaenas, besides the abundant fragments of their prey. 



This fragment, found in a Pleistocene formation at Pikermi, Greece, shows 

 two incisors, two molars, and a canme. The original is in the University 

 Museum, Munich. 6x2.

Skeleton (cast). 

 This interesting and 

 well preserved fossil 

 rewarded the early 

 geological pursuits 

 (1828) of the distin- 

 guished author of 

 the "Silurian Sys- 

 tem." The novel oc- 

 currence of an entire 

 carnivorous quad- 

 ruped regularly im- 

 bedded in stone, as 

 well as some peculiarities in its analom3^ make this a singular)}- unique speci- 

 men. Von Meyer tirst proposed the name of Canis pahistris, and M. de Blaiu- 

 ville called it Vulpes CEningensis; but after careful examination, Professor 

 Owen gave it an intermediate position between the Polecat and Dog. The 

 first premolar is smaller, and the third and fourth larger, than in the Fox, and 

 all the teeth are more closely set than in the genus Canis, though the dental 

 formula is the same. The general breadth of the feet, in proportion to their 

 length, is greater than in any canine species, and it is this robust character of 

 the feet which indicate an affinity to the Viverrine group. The tail is longer 

 in proportion than in the Dog, though not so long as in the Fox. The verte- 

 brse number the same as those of the Fox. The fossil was discovered in the 

 lacustrine beds, called "Molasse" (Miocene), at CEningen, near Constance, 

 and is now in the British Museum. Size, 3 ft. x 2 ft.
