Types. Four syntypes of T. pileus are ZMA Coel. 7352 and 1326. Type Locality: 5°43'N 119°40'E (Sulu Archipelago ), 522 m.

The holotype of E. australiae ( Figs. 6D,E) is deposited at the Macleay Museum. Type Locality: Port Stephens , NSW, 146 m.

Remarks. Although Endopachys australiae has nomenclatural priority over C. pileus by several decades, that name was never used a valid name after its original description, whereas pileus has been widely used and accepted for this common deep-sea coral. Thus, according to article 23.9.1 of the ICZN (1999), Endopachys australiae is considered to be a nomen oblitum and C. pileus to be a nomen protectum.
