PLEISTOCENE AND RECENT UNGULATE 



CHARACTERS SHOWN BY NOTOTHERIA. 



Rhinocerotidce. The Nototheria approach these perisso- 

 dactyle animals in the structure of the palate, the short 

 neck, the horn, or horns, being developed in the mid- 

 cranial line. The horns are also similarly nourished by- 

 anterior central and centro-lateral vascular supplies, but 

 manifested a stirp character, in a central basal blood sup- 

 ply, not found in Rhinoceroses. Thev also approach these 

 ungulates in the morphology of the occiput. 



Taperidce. The Nototheria approach these Ungulates 

 in tho matter of bilophodont teeth. In having one pre- 

 molar deciduous, but show a stirp trend in its being the 

 fourth, instead of the first. They also show the Tapir 

 character of not developing a third trocanter to the 

 femur. 



AS AN INDIVIDUAL STIRP. 



The Nototlu rin show in the skeleton, marsupial 

 bones, clavicles, an entepicondyloid foramen. Pentadactyl 

 feet and hands. Longer lumbar regions than either 

 Tapirs or Rhinoceroses possess. Premolars reduced to a 

 single pair in either jaw. Incisors retained. 



INTER-STIRP CHARACTERS. 



Within the stirp the Nototheria display a blending of 

 Kangaroo, Wombat, and Native Rear characters, in ad- 

 dition to their own osteolosv. 



RECAPITULATION. 



In the Nototheria we thus find a group of animals 

 that in Tasmania became extinct late in pleistocene 

 times, that were gem ralised, and yet, in part, specialised. 

 They retained the racial characters that can be relet 

 to five geological periods — that is, from the pre-Eoccne to 

 the latest pleistocene. They show similar develop) 

 to those of the pcrissodactyle ungulates, and without 

 leaving a single modern representative to carry on their 

 race, in totality, they have left many characters scat- 

 tered through their marsupial alii s the Kangaroos, 

 Wombats, and Native Bears, who still grace our wood- 

 lands to-day.
