| Planorbid shells are abundant in the sediments of the fresh water lake of Steinheim am Albuch throughout its depositional history. They were studied repeatedly after Hilgendorf's (1867) initial work. He had all different morphs that appeared during the long lasting lake history related to a single founder species that developed into several lineages, one of which was designated as 'main-branch' with large conspicuous morphs. Most subsequent studies are concerned with that branch. Based on new material and aided by SEM studies of the protoconchs, the small side-branch morphs have been restudied and evolutionary lineages are reconstructed. As a result the phylogenetic lineages of planorbids from lake Steinheim can be considered to have evolved from a single... |

| The following groups of Mesozoic Caenogastropoda are discussed here: Cerithioidea and Littorinoidea-Rissooidea seemingly merging with each other during Triassic times; the fresh water and land snails of the Viviparoidea and Cyclophoroidea with unknown marine relatives but a Mesozoic history; the Vermetoidea, Turritelloidea and Campaniloidea with a late appearance in the Mesozoic; the Ctenoglossa with a continuous history from the Middle Palaeozoic to modern times; the Subulitoidea, Murchisonioidea and Loxonematoidea with Palaeozoic ancestors but unclear Middle Mesozoic relations; the Purpurinoidea as potential ancestors and relatives of the Stromboidea, the latter suddenly appearing in the Jurassic; the Heteropoda and Vanikoroidea with possible relation to... |

| In the St Cassian fauna of Late Triassic (Early Carnian) age gastropods with protoconch coiled in opposite direction to the teleoconch are common and belong to a number of quite different taxa. Twenty nine of these are here described, 11 of them for the first time: Promathilda misurinensis sp. nov., Turrithilda cassiana sp. nov., T. dockeryi sp. nov., Tirolthilda seelandica gen. et sp. nov., T. nuetzeli sp. nov., Tofanella cancellata sp. nov., Cristalloella cassiana gen. et sp. nov., C. sinuata sp. nov., C. delicata sp. nov., Stuorilda cassiana gen. et sp. nov., and S. tichyi sp. nov. All are newly defined and placed in the Mathildoidea. This connects the Triassic species of that superfamily with the modern Heterostropha (= Heterobranchia). In the family... |

| Se presentan datos con respecto a la forma de vida y del ambiente de 13 mesogastropodos superiores. Los huevos de Strombus gigas, S. pugilis, Polinices lacteus, P. hepaticus, Natica livida, N. canrena, Morum oniscus, Cypraecassis testiculus, Charonia variegata, Cymatium nicobaricum, C. pileare, Bursa cubaniana y Tonna galea se describen en detalle y se caracterizan las larvas recién nacidas. En la mayoría de las especies mencionadas se pudo determinar el tiempo de desarrollo desde el huevo hasta su nacimiento. Los huevos aquí descritos son comparados con lo que se conoce de la literatura, según sus caracteres morfológicos se distinguen seis tipos de cápsulas y masas de huevos. |
