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.
