Resumo
The study of 41 individually specimes of Subulina octona (Bruguiére. 1789) during 182 days indicated that oviposition occur between 10pm and 10am. The interval between ovipositions was from seven to 31 days. In the eggs, the greatest axis was 1.5-2.0mm while the smallest was 1.2-1.6mm. The lenght of shell of recently ecloded snails was 1.3-1.8mm. The growth rale of adult snails was measured and they grew more in the first 45 days than in the last 75 days subsequent of the study.
