	abstract = {<p>We define the notion of a $(P,\tilde{P})$-structure on a universe $p$ in a locally cartesian closed category category with a binary product structure and construct a $(\Pi,\lambda)$-structure on the C-systems $CC(C,p)$ from a $(P,\tilde{P})$-structure on $p$. We then define homomorphisms of C-systems with $(\Pi,\lambda)$-structures and functors of universe categories with $(P,\tilde{P})$-structures and show that our construction is functorial relative to these definitions.The proofs in this paper rely on the general constructions of the previous paper "C-systems defined by universe categories: presheaves". Keywords: Type theory, Contextual category, Universe category, dependent product, product of families of types</p>
