 "Comus" was armed with two 7-inch muzzle-loading rifles, eight 64-pounder muzzle-loading rifles and four breech-loading 6-inch 80-pounder guns, but the breech loaders proved unsatisfactory.The rest of the class were provided with four more 64-pounders in place of the 6-inch breech loaders, except for "Canada" and "Cordelia", which exchanged all the muzzle loaders for ten of the new 6-inch Mk II breech loading guns.A selection of light guns and Nordenfelt quick-firing guns, as well as a pair of torpedo carriages, were also carried.
