'Silver Elephants are leapers that can reach all squares on the board and can also be very nice and useful short-range attacking pieces. They are similar in value to the long-range color-bound Bishops and stronger than the leaping Knights.'
In Peter Aronson's White Elephant Chess this piece is called a Great Elephant. I would value this shortrange piece halfway between a Bishop and a Rook on a 10x10 board.
