Abstract: We prove that for a general canonical curve $ C \subset \mathbb{Z}^{g-1}$ of genus $ g$, the space of $ {\lceil\frac{g-5}{2}\rceil}$th (last) scrollar syzygies is isomorphic to the Brill-Noether locus $ C^1_{\lceil \frac{g+2}{2} \rceil}$. Schreyer has conjectured that these scrollar syzygies span the space of all $ {\lceil \frac{g-5}{2} \rceil}$th (last) syzygies of $ C$. Using Mukai varieties we prove this conjecture for genus $ 6$, $ 7$ and $ 8$.
