| Crustacea (dynomenid crabs and cirripedes) from the upper Cenomanian-lower Turonian nearshore, shallow-water bioclastic limestones to marly siltstones found along the southern and eastern margins of the Bohemian Cretaceous Basin (BCB) are described. Crabs are rather rare in this area, and mostly restricted to fragmentary pereiopods, i.e., isolated claws or dactyli. In view of the confused taxonomy of isolated claws, their proper identity could not be determined; they were mostly referred to the necrocarcinid genus Necrocarcinus Bell, 1863. A recent re-examination of material deposited in the collections of the National Museum (Národní Muzeum, Prague), and of new finds, has revealed that all allegedly necrocarcinid pereiopods and nearly all carapaces from... |

| Ovisac secretion by the paired colleteric glands of Sacculina carcini and Heterosaccus dollfusi (Rhizocephala, Sacculinida) was documented and studied at the ultrastructural level. Preparatory to oviposition, the epithelium of each colleteric gland secretes one branched, elastic, transparent ovisac. The ovisac wall consists of a reticulated inner zone, secreted first, and a dense outer zone. After secretion, the ovisac detaches from most of the secretory epithelium but remains anchored proximally in the gland until oviposition ends. The exterior ovisac surface is predominantly smooth and impervious. Proximally, however, the surface is irregular and perforated. During oviposition the eggs enter the paired ovisacs, forcing the ovisacs through the ovipores... |
