little creature was then shipped for Dublin ; but 

 unfortunately reached its destination in a dying 

 state, and only breathed for about five minutes 

 after reaching the Gardens. The body was care-

 found in the Proceedings of the Royal Irish 

 Academy for 1873-4. 



In consideration of the great rarity of Hippo- 

 potamus liberiensis, I have compiled a census of 

 museum specimens which may interest students. 

 The examples thus recorded are as follows : 



1. Skull of young adult animal, with complete

 Museum at South Kensington. 



2. Skull of aged animal, with obliterated sutures, 

 worn teeth, and lower jaw missing. This and the 

 preceding are the specimens originally described 

 by Dr. Morton, in 1849, and are now in the 

 Museum of the Royal Academy of Sciences, at 

 Philadelphia. 



3. Mounted skeleton, from example obtained on 

 the St. Paul's River, Liberia, described in 1852 by 

 Dr. Leidy, in the Proceedings of the Academy of 

 Natural Sciences of Philadelphia, and still pre-

4. Skin sent over in pickle, and described in 

 1868 by M. Alphonse Milne Edwards. He figures
