in Florida in Association with Extinct Vertebrates. 15 



Of mammals found in association with the human bones 

 twelve species may be recognized. Of these five or six are 

 extinct, the remainder being identical, so far as can now be 

 determined, with existing species. Of the extinct species, one, 

 an armadillo, is referable to the extinct genus Chlamytherium, 

 while another, a rabbit which is quite unlike any rabbit now 

 known in the United States, is probably to be referred to a new 

 extinct genus having affinities possibly with the genus Romer- 

 olagus of Mexico or Pronolagus of South Africa. In addition 

 to mammals there are found in this bed bones of crocodilians, 

 fishes, birds, and a variety of turtles, as well as plant and insect 

 remains. The human fossils are mineralized and in all respects 

 preserved in the same manner as the associated vertebrate 

 fossils. 



List of Mammalian Species from Bed ]STo. 3. 



Chlamytherium septentrionalis. This extinct armadillo-like ani- 

 mal is represented by dermal plates taken from the muck 

 and sand layers about one foot above the human remains. 

 The articulating margins of the plates, although very delicate, 

 are uneroded. 



Lynx sp. Represented by a tibia and a lower jaw lacking only the 

 incisor teeth. This lynx differs from the modern lynx now 

 found in Florida by a large canine which crowds upon and 

 reduces the space available for the incisors ; the diastema 

 between the canine and the premolars is reduced, the jaw 

 as a whole is thicker, and the teeth more closely crowded than 

 in the modern species. 



Rabbit Gn., sp. nov. Represented by right and left jaws, taken 

 from the muck eighteen inches above the human radius. In 

 the structure of the first molariform tooth this rabbit differs 

 from any known from the United States and resembles in this 

 respect the aberrant Romerolagus known only from the west 

 side of Mt. Popocatepetl in Mexico, and the South African 

 rabbit, Pronolagus. 



Vulpes pennsylvanicusf Represented by a part of the lower jaw 

 with two premolars preserved. 



Neo fiber alleni. Represented by the front part of the skull and 

 two lower jaws. 



Oanis sp. Represented by a scapula, humerus, radius and tibia, 

 indicating a canid of more stocky build than the coyotes. 



Sigmodon sp. Represented by a right lower jaw. 



Odocoileus sp. Represented by a part of the lower jaw and various 

 parts of the skeleton. 



Lutra canadensis. Represented by humerus, femur and tibia. 



Didelphis virginiana. Jaw, humerus and ulna.
