KOHMAN Y . ARAKAWA
Locality : Shiju-shima, near Onomichi, Hiroshima, Japan.
Measurements: Faecal pellets shed by an animal with 4 3 4 mm high
shell are 0.52 mm in average breadth.
Later nulidae
Pellets of members of this family are short rods with irregular outline, which should be referable to Pellet-type 11-4.
85. Laternula (LaternuZina) Jtexuosa (Rve)
This and the following species are mu& alike in pellet characters.
They are in the form of a rod, usually broken into short lengths. They
are somewhat blurred in outline. The surface is not smooth but is
occasionally broken by transverse cracks (Pellet-type 11-4).
Locality : Tomioka, Kumamoto, Japan.
Measurements : Breadth of pellets discharged by a specimen 32.0 rnrn in
shell length is 0.20 mm.
86. L. Zimicola Rve (PI. 4-46)
“ This species sheds roughly oval pellets with truncate ends. They
are very firm and densely packed with fine detritus. They are coloured
yellowish-brown and occasionally marked with clefts. The pellets
average 0.60 mm in length and 0-31 mm in diameter.” (Arakawa, 1963,
p. 207, Text-Fig. 6, F-C.) (Pellet-type 11-4).
Thraciidae
87. Cyathodonta (Erimiothracia) concinna (Gould)
sistency (Pellet-type 11-4).
Locality : Tomioka, Kumamoto, Japan.
Measurements: From an animal of shell length 8-5 mm, pellets were
0.24 mm broad on average.
Ly onsiidae
88. Lyonsia ventricosa Gould
Faecal pellets of this species closely resemble those of the genus
Latemula. They are rod-shaped but somewhat irregular and flocculent.
They are usually cut by numerous clefts. They are coarse in texture and
greyish-brown in colour (Pellet-type 11-4),
Locality : Kaneda Bay (50 m in depth), Japan.
This species produces short rod-like pellets with soft and loose con-
