The Horn in C transposition doesn't appear to be right. It should be one octave lower than written. Also, it should be starting on Treble Clef (G Clef) instead of Bass (F). So unless this changes, the Horn in C is no different than the High C Horn (C alto) besides their ranges.

The cornet (/ˈkɔːrnɪt/, US: /kɔːrˈnɛt/) is a brass instrument similar to the trumpet but distinguished from it by its conical bore, more compact shape, and mellower tone quality. The most common cornet is a transposing instrument in B♭, though there is also a soprano cornet in E♭ and cornets in A and C.
