Basal part of zoarium, X30 showing primary disk, rhizoids, basal tubulus and dichotomous mode of branching. B. Fertile internode, X20, with full grown gonozoid (G.) twisted almost 180°. distant than the zoarial width. The basis ramae is wide and placed at a zoarial bend. Measurements.—Diameter of peristome, mm.; distance of ori- fices, ; and width of segments, Affinities.—In its great fragility and in its numerous tubes to the segments, this species can be compared only with Crisia elongata Milne Edwards, 1838, of Australia, but it differs from the latter in a slightly greater distance between the tubes ( mm., in place of mm.). Species of Crisia live in small bushes attached to floating algae; they have therefore never lived where they are dredged in the condition of detached Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States National Museum; Smithsonian Institution; United States.
