This paper deals with two ovulid species collected at Canopus Bank, off Fortaleza, Ceará, Brazil: Pseudosimnia vanhyningi (M. Smith, 1940) and Spiculata bijuri Cate, 1976. The samples consist of empty shells. This is the first time both have been reported on the northeastern Brazilian coast, therefore this is the southernmost record of them. Their taxonomy is revised based on the analysis of some variants of the shell that have been attributed to other species and genera. Aperiovula juanjosensii Perez & Gomez, 1997, and S. advena Cate, 1978, are proposed to be new synonyms of S. bijuri.

Columbella costa, a new species from off Saquarema, Rio de Janeiro, Brazil, is described. This new species is characterized by its obesity; high spire; smooth, glossy surface; and by a deeper water habitat of 30-35 m. This is the second species of the genus found off the Brazilian coast and the only one occurring in its bathymetric range.
