-intobject represents a (long) integer.  This is an immutable object;
+PyIntObject represents a (long) integer.  This is an immutable object;
 an integer cannot change its value after creation.
 
 There are functions to create new integer objects, to test an object
 for integer-ness, and to get the integer value.  The latter functions
