That's normal. Multiple desktops is part of Mission Control in OS X Lion and Mountain Lion (10.7, 10.8). On you Dock, next to Finder you'll find the Mission control button. Click it and hover you pointer over the unwanted desktop and click on the litte 'x' that appears to remove the desktop. Move the pointer to the top right corner of Mission Control and you'll see the option to add more desktops.
