Abstract
Five bathyal species of cheilostome Bryozoa have been found on a submarine volcano off the Canary Islands, on dead skeletons of the madreporarian Madrepora oculata Linnaeus. Three of them are new to science. For one species, the introduction of a new genus and family is necessary. In addition, the generic assignation of Cribrilina alcicornis Jullien is revised, including this species in Distansescharella d'Orbigny. Tessaradoma boreale (Busk) is cited for the first time from the Canary Islands.

Acknowledgements
I wish to thank Dr Luis García Cacho, from the Museo Nacional de Ciencias Naturales (Madrid), who kept the biological material from the expedition, and brought it to Seville, and also to my colleague at the University of Sevilla, Dr Pablo J. López González, specialist in Cnidarians, who noticed that there were Bryozoa on the surfaces of the coral and gave them to me. I am also indebted to the staff of the SMEUS for their kind help with the SEM pictures. The manuscript has been improved greatly by the comments and suggestions of an anonymous referee and one of the editors (P. J. Hayward) of the Journal of Natural History, whom I sincerely thank.
