Notophorus torquatus had a young one in ISHO, the first occasion 

 that the animal has bred in confinement in England (Solater, P. Z. S. 

 1800, p. 448). 



The skulls of the three old [males?], having large canine teeth, 

 are ratlier larger than the other, and they have a well-marked ol)- 

 long slightly sunk concavity in front of the orbits. 



One adult skull, in the Museum, with large short thick canines, 

 has this part of the skull, which is concave in the three other skulls 

 above referred to, flat. 



The angle of the lower jaw in the old skidl becomes much di- 

 lated, with a produced lower edge, making the skull appear higher 

 than the skull from an animal with all its teeth just developed, as 

 720 7i. 



2. DICOTYLES. 

 SkuU — side of the face in front and on the underside of the orbits 

 flattened, with a well-marked ridge on its lower edge : orbits small, 

 incomplete. The longitudinal ridge on the cheeks bent up in an 

 arched manner in front of the orbits, and then sliglitly indicated 

 parallel to the line of the forehead, becoming a large concavity on 

 the cheek beneath. Teeth large (see Blainv. Osteogr. Ongiiiigr. 

 Sus, t. 5, figured as Sus toniuatus). Tail rudimentary ; caudal ver- 

 tebra) nine (Gerrard).
