It's a mix of a Maltese and a Yorkie. Someone invented a cute name for it. They're sometimes called Yorktese. Some unscrupulous breeder decided that they would try to define the diff btwn a Yorktese and a Morkie by saying that a mother Maltese and father Yorkie is a Morkie and a mother Yorkie and a father Maltese is a Yorktese.
I don't have any pictures, but if you do a google image search for "morkie", it comes up with 203 pictures:
