Abstract:
   The coloration of Costa Rican Helicinidae has been studied, with special attention paid to the arboreal species. It is shown that either shell color or mantle pigmentation contribute to the coloration visible in the living animals. Ecological and systematic implications are given. This paper is supplementary to Richling (2004).
