Starting from the well-known quantum Miura-like transformation for the non-simply-laced Lie algebras B-N, we give an explicit construction of the Casimir WB3 algebras. We reserve the notation WBN for the Casimir W algebras of type W(2,4, 6,...,2N, 2N + 1/2) which contains one fermionic field. It is seen that WB3 algebra is closed and associative for all values of the central charge c.
