See section 7.2, "Conceptual Graphs and KIF", of his book, "Knowledge 
Representation":  "Although the KIF and CG notations look different, their 
semantics are identical".  (KIF being very close to FOL.)

(This underlying theme of FOL providing a common underpinning for various 
representations, including process descriptions as well as static object 
descriptions, is a recurring theme in the book.)

For examples of CGs and their translation to FOL (via KIF), see:

(which also directs the reader to chapter 5 of the book for discussion of 
the equivalence.)
