SYSTEMATICS OF MELICERITITID CYCLOSTOME BRYOZOANS 71 frontal length: frontal width: apertural length: apertural width: range = 0-77-1-05 mm range = 0-32-0-42 mm range = 0-38-0-59 mm range = 0-17-0-29 mm kenozooids (6 zooids from BMNH D57506) frontal length: range = 0-48-0-60 mm frontal width: range = 0-32-0-38 mm Remarks. The holotype specimen lacks unequivocal eleo- i zooids, as noted by Lang (1906) in his original description of Reptomultelea dixoni which is based entirely on this speci- men. However, eleozooids are present in most other colonies ( Figs 198, 199, 201). Among congeneric species, R. dixoni closely resembles R. sarissata Gregory, 1899 in the morphology of the eleozooid which has an elongate aperture and is often spatulate. However, although similarly pointed, the autozooidal apertures of R. dixoni lack the distal prolon- gations of R. sarissata apertures which give them a distinctive ogee arch-shape (Figs 282, 283). The proportion of kenozooids to other zooids varies greatly between colonies of this species. In some colonies ( BMNH D31844), kenozooids occupy about the same surface area and are more numerous than autozooids. The high proportion of kenozooids in colonies like this one are unre- lated to disturbances in growth caused by anastomoses of overgrowths. Colonies vary from lamellar to nodular in shape. Specimen , BMNH D57505 bioimmures a perished substratum of unknown identity which was roughly cylindrical in outline and ornamented by tubercles. Distribution.
