"This is the notebook that caused Gelus to die when he saved Misa. It would pass from Rem to Misa and eventually Mikami. This is the notebook that played the key role in the battle with Near." -- Death Note: How to Read 13
Gelus's notebook is black with white Shinigami writing on the front. The inside of the notebook contains white ruled pages.
Gelus fell in love with Misa Amane, and used his Death Note to kill the man who was destined to kill her. Gelus died as a result, leaving only his Death Note behind. The notebook was found by Rem, who took it to the Human World and gave it to Misa, who Rem believed was supposed to have it. Light eventually has Misa give up ownership of her notebook, and it is sent to Teru Mikami. Mikami's notebook is later stolen by the SPK. The notebook is eventually burned by Near, and it disappears from the Human World.
