I am told that a Himalayan (by "show") standards is to have a small physique (much smaller in size than their relative the Persian), round, flat face, perfectly round (not almond) shaped eyes. The standard is the flat, squished looking face with a high, flat nose. Though the doll face Himmys with a more traditional looking cat face are still classified as Himalayans, they are not permissible in shows.

The Ragamuffin is a purebred cat, not a mixed breed in the sense of a generic moggy, but it is a mixture of breeds. Basically, it's a Ragdoll that's been outcrossed with Persians, Himalayans, and domestic long haired cats. Since it's so closely related to the Ragdoll, some registries have been reluctant to recognize the breed. But Ragamuffins seem to be nice cats--I've never seen one, but I have seen Ragdolls, and wouldn't mind having one myself if I didn't have so many Maine Coons.
