FIGURES 38–44, Crepidula margarita anatomy. Fig. 38: visceral mass and pallial cavity separated from head­foot, ventral view. Fig. 39: same, ventral portion of visceral mass (floor of pallial cavity) sectioned longitudinally at left (right in Fig.) and deflected, some portions of gill filaments partially removed, pallial roof exposed. Fig. 40: pallial cavity roof, transversal section tangent to rectum. Fig. 41: visceral mass portion encroaching in pallial roof, ventral view, ventral membrane of pericardium mostly removed, only a short portion of gill shown. Fig. 42: head and haemocoel, ventral view, foot removed. Fig. 43: foregut, ventralslightly left view, nerve ring shown as in situ.
