Abstract
    Species of the genera Progoniada and Goniadella are recorded from off the Brazilian coast, from depths of 93 to 808 m. The description of Progoniada regularis is complemented with new data on the number of chevrons and micrognaths. Goniadella revizee sp. nov. is described; it differs from the five known species of the genus mainly in having acicular chaetae above the dorsal cirrus, together with 20-21 uniramous chaetigers. The proboscideal papillae of both species are illustrated by scanning electron micrographs.
