Scale bar = 50 urn. Notes. This appears to be a sister species to S. asper, a common Caribbean species. It is morphologically very similar except for the much broader and shallower sinus of the orifice, and in its more semicircular anter and double projecting condyles. As more material from the greater Caribbean is studied, a gradient in morphology between the Barbados material and S. asper may be found, but since orifice shape is one of the most strongly constrained characters in bryozoan species, we chose to describe it here as a separate species.

Colony made up of erect, unjointed, bifurcating, nonreticulate branches (Figs. 37A, B) attached by a cemented base. Zooids irregularly rhomboi- dal, their frontal walls of smooth-to-wavy calcification with only a few small marginal pores visible and with raised suture lines marking zooid boundaries (Figs. 38A, C)..
