How do I specify multiple constraints on a generic type in C#?

What is the syntax for placing constraints on multiple types? The basic example:

class Animal<SpeciesType> where SpeciesType : Species

I would like to place constraints on both types in the following definition such that SpeciesType must inherit from Species and OrderType must inherit from Order :

class Animal<SpeciesType, OrderType>
public class Animal<SpeciesType,OrderType>
    where SpeciesType : Species
    where OrderType : Order
{
}

You should be able to go :

class Animal<SpeciesType, OrderType>
    where SpeciesType : Species
    where OrderType : Order {
}
