A new species of the genus Vitrinella, Vitrinella kaykayae spec. nov., from Concepción, Chile, is described. It represents the first record of a species of this genus for that coast. The new species is compared with other species morphologically similar. 6 pp., 7 figs, gr. 8.

A new species of Dizoniopsis, Dizoniopsis apexclarus sp. nov., from Principe, Sao Tomé and Annobon is described showing differences with other similar species. 4 pp., 10 figs, gr. 8.

Columbella minor Scacchi, 1836 is revised in the genus Mitrella Risso, 1826, on the basis of its original description and figure, and of the study of shell material from Mediterranean and the nearby Atlantic. A neotype of C. minor is designated. C. minor takes priority on the older name Mangelia vitrea Risso, 1826 on the basis of the article 23.9 of the Code of Zoological Nomenclature. The variability of the shell morphology, of the shell decoration and of the animal chromatism is discussed. A sibling species ranging from Alboran Island to Northern Senegal is described as Mitrella hernandezi sp. nov. Its principal diagnostic features lie in a large white pupoid protoconch instead of a small brown pointed one in M. minor, and in a thin lattice-patterned periostracum instead of a thick coarsely wrinckled on in M. minor. 15 pp., 43 figs, gr. 8.…

A new species Olivella (Olivella) arionata is described from shallow waters off southern Brazil. It is recognitable by characters of colour, subsutural bnd, fasciole, and the lack of an operculum. The pillar structure of young forms shows si,ilarities to subgenus Olivina. 1+3 pp., 2+6 figs, 4.

Three new species of the genus Alvania collected in Sao Tomé Island are described. The new species are compared with others of similar morphology from the African coast. Some characters, usually considered typical of the genus Manzonia are commented on; these appear in some species here included in the genus Alvania. The latter genus probably constitutes a kind of catchall for many other valid genera that are at present inadequately defined. 10 pp., 23 figs, gr. 8.…

A new species, Onoba nunezi spec. nov., probably endemic of the Canary Islands is described. It is compared with other species of the genus and with Manzonia vigoensis, which is rather similar and with which was previously confused. At the same time a shell of Manzonia vigoensis from the Canary Islands is shown. Some remarks on this species and its geographical range and distribution are given. 7 pp., 12 figs, gr. 8.…

Four species, collected in the Cape Verde Islands, are described as new and asigned to the genus Euthria M. E. Gray, 1830. The new species are compared with other taxa from the Mediterranean Sea and the Cape Verde Archipelago. The genera Euthria, and Buccinulum are compared and the significance of the differences between them is discussed, leading to the conclusion that both genera are valid and should be kept separated. 13 pp., 31 col. figs, gr. 8.…

It is the first clearly costulate Iberian species, filling a morphological gap in the Iberian clade, and the largest species from the Cantabrian region, being the first species described from Asturias. 14 pp., 6 figs, gr. 8.…
