Skull with Ant- 

 lers. This splendid 

 fossil, the most re- 

 markable of the un- 

 questionably extinct 

 species of the Cervine 

 family, and common- 

 ly but erroneously 

 called " The Great 

 Irish Elk," is a true Deer, intermediate between the Fallow and Eein-Deer. 

 Though most abundant in, it is not peculiar to, Ireland, many remains having 

 been found in England and the Isle of Man. It was described so long ago as 

 1796, by Molyneux, who considered it a Moose. The top of the skull of this 

 noble animal, when standing erect, was ten feet from the ground. The antlers, 

 which far surpass those of any living Deer or Elk, have a span of about eight 

 feet ; they are branched and palmate, and were undoubtedly shed and reproduced 

 annually. The broad and massive subtriangular palm has a graceful oblique 

 twist, and sends off seven branches. The skull closely conforms to that of the 

 Rein-Deer, but there are no rudiments of upper canines. The vast weight of this 

 antlered skull was supported by cervical vertebrae of extraoi'dinary develop- 

 ment. The M. was cotemporaneous with the Mammoth, but probably became 

 extinct before the creation of Man. This skull belongs to a skeleton perfect in 

 all its parts, and of unusually large dimension, which was discovered in 

 the Pleistocene deposits of shell-marl that underlie the peat-bogs in the neighbor- 

 hood of Limerick, Ireland, and is now in the private Geological Cabinet of Mr. 

 Ward, Rochester. Size of skull, 22 x 10. Price of skull with antlers, packed, 

 $30.00 ; with mountings, $35.00, (Antlers in nine pieces unpainted.)

No. 48. Sivatherium giganteum, Falc. and Caut. 



Skull (Male). This singular pachyder- 

 moid Antelope exceeded the Rhinoceros in 

 size. The head was very large, broad but 

 short, and carried four horns : the first pair 

 resembled those of the Cow, and was placed 

 just between and above the orbits; behind 

 these was the other pair, palmated and branch- 

 ing, like those of the Elk. The posterior 

 part of the cranium was enormously develop- 

 ed and cellular as in the Elephant. The face 

 was short ; the eyes small and lateral ; and 

 the nasal bones were prolonged into a pointed 

 arch, indicating a proboscis. The very inclin- 

 ed direction of the front of the face, in rela- 

 tion to the triturating surface of the teeth,
