As far as I've read a hybrid between a Leopard and a Tiger is called a Dogla. Leopard and Jaguar are two different big cats, don't know what a cross between a Jaguar and Tiger is called, or a Jaguar and a Leopard for that matter. Hope this helps.
There have been no reported true hybrids of a leopard and tiger. Sometimes Ligers can keep their spots from childhood, causing a spotted/stripped look.
