A new species of Dolicholatirus Bellardi, 1884 is described and compared with appropriate congeners. The newly described species is known from Egypt and Mauritius Island. New taxa: Dolicholatirus maryseae n. sp. 4 pp., 1 plate, 4.

A new species of Harpa Röding, 1798 is described as Harpa lorenzi n. sp. It is compared with the only closely related species within the genus, Harpa cabriti P. Fischer, 1860. / Morum (Oniscidia) concilium n. sp. from Inhambane, Mozambique, differs from its congeners by the sculpture of the dorsum, the reduction of interstitial riblets, unpaired labral teeth and other subtle conchological features. It links members of the genus from the Indian Ocean with those from the Pacific. 7 pp., 2 plates, 4.

Morum (Oniscidia) morrisoni n. sp. from Queensland, Australia, has hitherto constantly been confused with Morum (Oniscidia) grande (A. Adams, 1855). It differs by its dorsal sculpture consisting of more distinct and narrower, more widely spaced varices with less developed lamellae in between. The shape is more angular, the spiral whorls less ventricose, and the body whorl narrowly tapering anteriorly. The columellar shield is usually less developed and less coarsely pustulose. 6 pp., 2 plates, 4.

A new species of the family Columbellidae, Mitrella lorenzi n. sp., is described from southern Papua New Guinea. The new species is compared with Mitrella vosvictori Monsecour & Monsecour, 2009 from the Philippines and Mitrella australis (Gaskoin, 1851) from Australia. 4 pp., 1 plate, 4.

After studying more than 5000 shells belonging to the family Cassidae, we tried to judge objectively, avoiding both splitting and lumping and thus only presenting our survey's finds. So, according to this study, 98 species are recognised, divided among the Genus Cassis Scopoli, 1777, Subgenus Cassis s.str. Scopoli, 1777, Subgenus Hypocassis Iredale, 1927, Genus Cypraecassis Stutchbury, 1837, Subgenus Cypraecassis s.str. Stutchbury, 1837, Subgenus Levenia Gray, 1847, Genus Galeodea Link, 1807, Genus Sconsia Gray, 1847, Genus Microsconsia Beu, 2008, Genus Oocorys P. Fischer, 1883, Genus Dalium Dall, 1889, Genus Eucorys Beu, 2008, Genus Phalium Link, 1807, Genus Casmaria H. & A. Adams, 1853, Genus Echinophoria Sacco, 1890, Genus Semicassis Mörch, 1852, Subgenus Semicassis s.str. Mörch, 1852, and Subgenus Antephalium Iredale, 1927. Since the past few decades DNA surveys have revolutionised nearly all areas of biological research, including malacology. However, we deem it necessary to state that this book is strictly conchological and that it was compiled for the use of those who wish to acquire an elementary acquaintance with the subject, as well as for authors and others who (eager to extend their knowledge and to pursue their researches) require a book of reference containing a general outline of what has been done by those who have trodden the same path before. 251 pp., 131 color pls, num. text figs, hc 4.
