Notice that $\left.\text{vii}^{\circ}{}\middle/\text{III}\right.$ in minor is not included because it is $\left.\text{ii}^{\circ}{}\right.$. Notice also that $\left.\text{vii}^ø{}^{7}\middle/\text{III}\right.$ has no accidentals—it is the same as $\left.\text{ii}^ø{}^{7}\right.$ but functions differently. The $\left.\text{ii}^ø{}^{7}\right.$ chord has pre–dominant function and progresses to $\left.\text{V}\right.$ whereas the $\left.\text{vii}^ø{}^{7}\middle/\text{III}\right.$ chord progresses to $\left.\text{III}\right.$.
