96. Cardium edule L.
“ Bei den Lamellibranchiern sind ebenfalls Kot-Pillen von ovalem
oder rundlichem Umriss haufig (Cardium edule).” (Schafer, 1953, p. 83,)
(Pellet -type I- 1 ? )

Fig. 9. Faecal pellets of: A. Pseudochama retroversa; B. Gorbiciila japonira; C. Tridacna
maxima (above, anus ; below, faecal pellet).
97. C. quadragenarium (Conrad)
“ The faeces of clamlike forms such as Paphia, Schizothaerus and
Cardium showed a definite linear segmentation.” (Edge, 1934, p. 80,
Fig. 2.) (Pellet-type IA-3).
98. Bulvia hungerfordi (Sowerby) (PI. 2-19)
This and the following species are much alike in pellet shape. The
only distinct difference between the pellets lies in the ratio of length to
breadth; it averages 1.85 in the present species and 1.3 in P. mutica
(Pellet-type IA-3).
Locality : Tomioka, Kumamoto, Japan.
