KEY WORDS: breeding cycle, keyhole limpet, larval development, Fissurella
Species of the Fissurella Bruguiere, 1789 genus, commonly known as "lapas" or "chapes," are among those gastropods frequently consumed by the coastal inhabitants of Chile (Huaquin et al.
Fissurella nigra Lesson, 1831, is one of the principle species of keyhole limpet caught in southern Chile (Bretos et al.
Fissurella species are gonochoristic (sexes are separate).
Female and male specimens of Fissurella nigra with a shell length of over 50 mm were transferred to the laboratory and conditioned during the months of July and August (winter) 1994, in preparation for spontaneous spawning: conditioning was achieved by maintaining specimens in darkness at 12[degrees]C, and feeding ad libitum with the red alga Gracilaria chilensis.
Three of the four development stages described by Ward (1966) were identified in the female gonad of Fissurella nigra.
Based on the results obtained for Fissurella nigra, it can be concluded that its breeding characteristics are common to those of arqueogastropods and to other species of the Fissurella genus inhabiting the Chilean coast.

KEY WORDS: Fissurella volcano, juvenile, Baja California, limpet
The volcano keyhole limpet Fissurella volcano (Reeve 1849) is a prosobranch gastropod of the family Fissurellidae.
Comparisons are not possible beyond the planktonic veliger larval stage because the available information about other Fissurella species does not include the later developmental stages.
