On the page listing all the journals, hit the gear in the bottom right, then Edit Journals, then the X in the corner of the journal you want to delete.

To delete a journal: http://help.apple.com/iphoto/iphone/1.0/#blnk26d8ed3e
Note: You can only delete a journal from the device which published it. So if the journal was created by another one of your iOS devices and is being shared through iCloud, delete it from the other device.
Hope that helps.

What happens if the iOS device that was used to create and publish journals has been lost/stolen? The device has been removed from managed device list in iTunes account, and erase pending via Find iPhone
