"Class object." It's splitting hairs a bit, but that is how the JLS
refers to them.
Example:
"In the Java virtual machine, every object belongs to some particular
class: the class that was mentioned in the creation expression that
produced the object (§15.9), or the class whose Class object was used to
invoke a reflective method to produce the object..."

C.class is a class object. "Class" as I use it above (usually with a
lower case 'c') is more the concept of a class, rather than its Java
implementation of the class. (Rather the same way that the JLS uses
'class' to refer to the general concept of a class in OOD, for example
that section of the JLS I quoted above.)
That said, you're not really wrong to point out it's really the
instances that have references to their enclosing class.
