1 13. V . mindanensis (Smith) (Pl. 2-20)
(Pellet-type 11-4).
Locality : Tomioka, Kumamoto, Japan.
Measurements : For an examined animal, the breadth of the pellets was
9.08 mm.
Description of the pellet for V . micra may be applied to this species
114. Veremolpa sp.
The pellets of this and the above three species are so much alike in
nature and form that it is impossible to draw a marked distinction
between them (Pellet-type 11-4).
Locality : Tomioka, Kumamoto, Japan.
Measurements : In specimens examined the breadth of the pellets was
0.26 mm.
115. Venus ( Ventricoloides) foveolata Sowerby
Faecal rods are usually chapped on the surface by occasional cracks.
They are coarse in surface texture, containing a considerable amount of
undigested matter and sand grains. At times, this species sheds rodlike pellets packed by filamentous constituent rodlets (Pellet-type 11-4).
Locality : Sagami Bay (87-95 m in depth), Japan.
Measurements : Faecal rods shed by an animal of shell length 37.5 mm
were 0.32 mm and the constituent rodlets were 0.10 mm broad.

definitely ascertained as no others were shed (Pellet-type 11-4).
Locality : Shikanoshima, Fukuoka, Japan.
Measurements : For an examined animal, a pellet was 0.46 mm broad.
117. Anornulodiscus spuamosus (L.)
Ruditapes, Pitar and Veremolpa (Pellet-type 11-4).
Locality : Tomioka, Kumamoto, Japan.
Measurements : From a specimen with a shell 25.0 mm long, pellets fluctuate in breadth between 0.15 and 0-20 mm.
The faecal rod is somewhat blurred in outline and has irregular
Though it was conceivably atypical, this was not
The pellets in this species are very similar in type to those of
