either side.  The colour of the end should be black, and it should be both deep and wide with open nostrils.  JAW—­The muzzle must be square and deep, and the lower jaw wide between the branches, leaving plenty of space for the tongue, and for the attachment of the lower lips, which should completely conceal the teeth.  It should also be turned up or “finished,” so as to allow of its meeting the end of the upper jaw turned up in a similar way, as above described.  EARS—­The ears must be long, so as to approach the ground.  In an average-sized dog they measure twenty inches from tip to tip, and some reach twenty-two inches, or even a trifle more.  They should be set low on the head, hang flat to the sides of the cheeks, and be heavily feathered.  In this last respect the King Charles is expected to exceed the Blenheim, and his ears occasionally extend to twenty-four inches.  SIZE—­The most desirable size is indicated by the accepted weight of from 7 lb. to 10 lb.  SHAPE—­In compactness of shape these Spaniels almost rival the Pug, but the length of coat adds greatly to the apparent bulk, as the body, when the coat is wetted, looks small in comparison with that dog.  Still, it ought to be decidedly “cobby,” with strong, stout legs, short broad back and wide chest.  The symmetry of the King Charles is of importance, but it is seldom that there is any defect in this respect.  COAT—­The coat should be long, silky, soft and wavy, but not curly.  In the Blenheim there should be a profuse mane, extending well down in the front of the chest.  The feather should be well displayed on the ears and feet, and in the latter case so thickly as to give the appearance of their being webbed.  It is also carried well up the backs of the legs.  In the Black and Tan the feather on the ears is very long and profuse, exceeding that of the Blenheim by an inch or more.  The feather on the tail (which is cut to the length of three and a half to four inches) should be silky, and from five to six inches in length, constituting a marked “flag” of a square shape, and not carried above the level of the back.  COLOUR—­The colour differs with the variety.  The Black and Tan is a rich glossy black and deep mahogany tan; tan spots over the eyes, and the usual markings on the muzzle, chest, and legs are also required.  The Ruby is a rich chestnut red, and is whole-coloured.  The presence of a few white hairs intermixed with the black on the chest of a Black and Tan, or intermixed with the red on the chest of a Ruby Spaniel, shall carry weight against a dog, but shall not in itself absolutely disqualify; but a white patch on the chest or white on any other part of a Black and Tan or Ruby Spaniel shall be a disqualification.  The Blenheim must on no account be whole-coloured, but should have a ground of pure pearly white, with bright rich chestnut or ruby red markings evenly distributed in large patches.  The ears and cheeks should be red, with a blaze of white extending from the nose
