1. In a small bowl, toss together the zest and the parsley and reserve the mixture.
2. In a heavy skillet, cook the garlic in the butter over moderately low heat, stirring occasionally, for 1 minute. Increase the heat to high and cook the garlic, stirring, until it is pale golden.
3. Add the scallops, stirring occasionally, for 1-1/2 to 2 minutes, or until they are just firm. Transfer them with a slotted spoon to a platter.
Add the wine to the pan juices. Boil the mixture, stirring, until it is reduced to about 1/4 cup. Season the sauce with salt and pepper.
4. Spoon the sauce over the scallops; sprinkle with the reserved parsley mixture. Serve with the Italian bread.
