Description
Summary:Kampylaster incurvatus Koehler 1920 FIGURE 6A–G Kampylaster granulatus Koehler 1920: 8 ( nomen nudum ) Kampylaster incurvatus Koehler 1920: 138; Fisher 1940: 150; Madsen 1955: 13; H.E.S. Clark 1963: 48. Diagnosis Body weakly stellate (R/r=1.0 at R=1.1.7). Marginal plates and lateral edge with round granules, forming rounded, thick edge with close-set granules extending onto the distal actinal intermediate areas adjacent to the inferomarginals (Fig. 6C). Granules round, homogeneous in size and shape, close set (Fig. 6B, G). Furrow spines, 3–4, elongate, unwebbed, widely spaced in transverse series relative to tube foot furrow. Comments One specimen (USNM 1183749) was found with 12 brooded juveniles (Fig. 6C, D, E). This is the first account of brooded juveniles since Fisher (1940) described brooding specimens from the Ross Sea. Juveniles described herein are slightly larger (R= 18 mm) than those described by Fisher (R= 15 mm). Three were found in the mouth cavity rather than adjacent to the mouth.
