Abstract

Early development of two species of ranellids, Cymatium (Monoplex) pileare and
C. (Linatella) cutaceum were studied in the laboratory. Females incubated the
egg mass for 12-25 days till fully developed larvae were hatched out through an
apical orifice of the egg capsule. The mean length and height of the released larvae
of C.(M.) pileare and C.(L.) cutaceum were 252 and 166 pm and 265 and 191pm
respectively. The percentage of hatching and larval development was 95.6 and
100 for CAM.)pileare and 93.7 and 94.6 for C.(L.) cutaceum respectively. The larval
development inside the egg capsule of these species are discussed.
