      In this paper, we first present several identities related to the inverse-conjugate compositions having parts of size $\leq 3$, the compositions into parts equal to $1$ or $2$, the compositions into odd parts and the compositions into parts greater than $1$. In addition, we provide a bijective proof of a relation for inverse-conjugate compositions having parts of size $\leq k$.
