Figure 4. a–f in A molecular and morphological review of the asterinid, Patiriella gunnii (Gray) (Echinodermata: Asteroidea)

Figure 4. a–f, Patiriella medius sp. nov. a, actinal view of holotype, R = 25 mm (NMV F92986); b, abactinal ray of paratype, carinally doubly papulate for about half ray length (ending at arrow), R = 23 mm (NMV F92988); c, abactinal interradius of paratype, with fine spination and fringe of fine inferomarginal spinelets, R = 24 mm (NMV F92988); d, cleared abactinal view of paratype, with few papulae and secondary plates, and carinal plates doubly papulate for about half the ray length, R = 22 mm (NMV F92988); e, actinal ambulacra and interradii of paratype, with suboral spines (arrows), and atypically 7 ambulacra, R = 23 mm (NMV F92988); f (above), common forms of abactinal spinelets; f (below), common forms of actinal spines proximal to ambulacrum, with adradial actinal spines (arrow) much shorter than subambulacral spines.
