Insectivtyra, Chiroptera, and Rodentia. 



Seals and 

 Walrus. 



Table-case, 

 No. 3. 



Sub-order 2. — Pinnipedia (Fin-footed). 



In the Table-case are exhibited remains of the marine Car- 

 nivora (Seals and Walruses) ; comprising a g-ood series of the 

 tusks, or canine teeth, of a large extinct Walrus (Trichechus 

 Huxleyi), from the Red Crag of Suffolk; a lower jaw of the 

 common Walrus (T. rosmarus), from the Dogger Bank ; and a 

 series of plaster casts of portions of skeletons of several extinct 

 species from the Antwerp Crag, the originals of which are pre- 

 served in the Brussels Museum. 



Hedgehogs 

 Moles, and 

 Shrews.

Lemurs.' 1 



Order III.— INSECTIVORA (Moles, Shrews, 

 Hedgehogs). 



This order comprises a number of small insect-eating 

 mammals, similar in many respects to the Rodentia ; but the 

 molar teeth ai*e always serrated with numerous small pointed 

 eminences or cusps adapted for crushing insects. One of the 

 oldest of these is the Necrogymnurus, from the Eocene of 

 Hordwell ; and a species of hedgehog (Erinaceiis) is found in 

 the Miocene deposits of Oeningen. Others occur in the Pleisto- 

 cene brick-earth of Grays, Essex, the Norfolk Forest-bed, etc. 



The Galeopithecidce, or " Flying Lemurs," have no fossil 

 representatives known.* 



Bats. 



Table-case, 

 No. 24. 



Order IV.— CHIROPTERA (Bats). 



The bats are characterised by having the fingers of the 

 fore-limbs enormously elongated and united by an expansible 

 membrane (or patagium) , which also unites the fore with the 

 hind limbs and the sides of the body. Some of the large 

 tropical bats are fruit-eaters ; while others are insectivorous in 

 their diet. They are found fossil in the Gypsum quarries of 

 Montmartre (Upper Eocene), Paris, the species being named 

 Vespertilio parisiensis ; others occur at Caylux, Sansan, and 

 Mayence. Rhinolophus is found in Kent's Hole, Torquay. 

 The Vampire bat, Vampyrus spectrum, with several undetermined 

 species of Phyllostoma, occurs in the cave-deposits of Brazil. 



Rodentia. 

 Table-case, 

 No. 24. 



Order V.— RODENTIA (Gnawing Animals). 



The Rodents, represented by the hares, rabbits, porcupines, 

 beavers, rats, mice, dormice, squirrels, and marmots, are cha- 

 racterised by the large development of their incisors, and the 

 absence of canine teeth.
