. Three or four very weak constrictions bounded by high ribs are present on the smaller limb. Ribs are prorsiradiate and rather weak on the smaller limb, where the rib index is 4; they bear minute nodate tubercles that border the narrow venter. Opposite tubercles are connected across the venter by very weak transverse ribs. Ornament weakens and almost disappears on the larger end of the elbow. Ribs and tubercles rejuvenate on the larger limb; ribs are rursiradiate, with a rib index of 6. Ribs are narrow on the flanks; they are straight, rounded, and narrower than the interspaces. Each rib bears a very small, nodate tubercle at the margin of the venter. Opposite tubercles are connected by transverse flattened ribs.

Well-preserved specimens have three minute longitudinal siphonal ridges on the elbow and adjoining part of the larger limb. Constrictions are widely spaced on the smaller limb, commonly at every ninth rib; they are occasionally present at every fourth to sixth rib on the larger limb.
