. Aboral series (i.e., all series aboral of inferomarginals) of arms proportionately delicate, not tightly and closely abutted; many small accessories intercalated among larger. Carinal series in part identified by positioning and alignment, series not demonstrably reaching central disk; carinals approximately equidimensional, ossicular central area enlarged, possibly flanged laterally. Arm adradialia appearing weakly aligned in single series, ossicles similar to, approximately aligned with carinals; carinal and adradial series possibly separated by granulate interareas. Madreporite on aboral disk, bordered laterally by enlarged, crescentic ossicles. Superomarginal series on arms clearly defined, differentiation weakening on disk. Arm superomarginals approximately equidimensional, central area of ossicle enlarged, successive ossicles appearing flanged; superomarginals approximately aligned in transverse series with both adjacent carinal and inferomarginal, the latter weakly exposed in aboral aspect. In oral aspect, inferomarginals of disk rectangular, aligned with and abutting adaxial series; appearing to become more nearly equidimensional, less clearly differentiated from adjacent ossicles on arms; surfaces of disk inferomarginals pustulate, possibly with thin, delicate spinelets, no enlarged spines. Intermarginals perhaps numerous on disk but recognition obscured by weakening of superomarginal definition; intermarginals appearing to reach or nearly reach arm tip. Axillary little enlarged relative to adjacent inferomarginals, polygonal, distal end truncated, proximal margin rounded. Actinal ossicles relatively few, quite large, similar in form to adjacent inferomarginals and axillary. Axials approximately equidimensional, sequential axials abutted laterally, not overlapping, approximately bilateral at transverse ridge; transverse channel not well-defined. MAO robust; circumorals enlarged, dumbbell shaped. Adaxial preservation varied among specimens, appearing approximately equidimensional, thought to lack a prominent nose.
