Abstract
Species (86) of Bryozoa are listed from collections from reefs in the Sudanese Red Sea, increasing the known faunal list by 30 spp. The abundance, in terms of numbers of colonies and the distribution of 19 spp. was analyzed over a range of 30 m depth. The character of Calyptotheca Harmer and Emballotheca Levinsen are briefly discussed. C. thornelyae is introduced for Lepralia subimmersa Thornley not MacGillivray and E. harmeri for E. acutirostris Harmer not Canu and Bassler. The new species, Calyptotheca heteroavicularia, C. nigra and C. sudanensis and Escharoides longirostris, are described.
