  In this note we construct conifold transitions between several Calabi-Yau
threefolds given by Pfaffians in weighted projective spaces and Calabi-Yau
threefolds appearing as complete intersections in toric varieties. We use the
obtained results to predict mirrors following ideas of \cite{BCKS,
Batsmalltoricdegen}. In particular we consider the family of Calabi--Yau
threefolds of degree 25 in $\mathbb{P}^9$ obtained as a transverse intersection
of two Grassmannians in their Plucker embeddings.
