Abstract in Portuguese
Foi estudada a morfologia externa e interna de Calliostoma adspersum, C. depictum e C. hassler, procedentes da costa brasileira. Tegula viridula também foi estudada como parâmetro comparativo externo. Foi possível averiguar características anatômicas que diferenciam todas as espécies entre si. Diferenças significativas foram encontradas principalmente nas seguintes estruturas: concha; coloração e papilas do pé; musculatura do odontóforo; esôfago anterior; estômago; ceco em espiral e alça intestinal. Calliostoma, de acordo com dados preliminares, diferencia-se dos demais troquídeos por apresentar: redução ou perda dos lobos cefálicos; pseudoprobóscide; presença de ampola renal; uma alça intestinal fora da hemocela e o músculo m1d do odontóforo.

Abstract in English
The external and internal morphology of Calliostoma adspersum, C. depictum and C. hassler, from Brazilian coast, was studied. Tegula viridula was also analyzed as outgroup. Anatomical characteristics that differentiate all species were found. The major differences were found mainly in the structures: shell; color and papillaes foot; odontophore musculature; anterior esophagus; stomach; spiral caecum and intestinal looping. Calliostoma, according to preliminary data, differentiates from other Trochidae in presenting: reduction or lost of cephalic lappets; pseudoproboscid; renal ampolla; intestinal looping outside haemocoel and m1d odontophore muscle
