<paragraph id="FA379293F1B53A516AEF124B1872D42D" pageId="7" pageNumber="8">Colonies are usually firmly attached to a hard substrate by a robust cylindrical base and stem (Fig. 1H) up to 2.5 cm in diameter, which, at the height of about 2 cm, bifurcates into two lamellae or sheets, each sheet increasing its surface area by folding and undulating its surfaces into a complex three dimensional structure. Large colonies may attain a height of about 8 cm and a width of 10 cm, colonies wider than tall being the norm. However, a subset of colonies from seven stations (see Material Examined), termed the &quot;digitate form&quot;, differ from the typical colony morphology in having dissected plates, resulting in numerous flattened lobes and clavate branches (Fig. 1E). Furthermore, one colony (Fig. 1F) is intermediate between these two extremes, suggesting that these shapes are simply variations of the same species.</paragraph>

Male ampullae (Fig. 3A) entirely internal, and elliptical in shape, the greater axis of the ellipse perpendicular to the branch surface, unlike that of the female ampullae. Male ampullae are up to 0.6 mm in greater diameter and 0.45 mm in lesser diameter, occurring in great concentrations and invariably present on almost any broken surface. Each ampulla communicates to the surface by a circular efferent duct, the duct about 0.07-0.09 mm in diameter, which is surrounded by small inward projecting granules, giving the pore a star-shaped appearance (Fig. 3

). Of the 81 specimens examined, 34 are female, 29 male, and 18 indeterminate in gender.

The digitate form is known only from the western Aleutian Islands from 27-366 m.</paragraph>
