摘要:

Marine algae collected from rock pools on Hood, Fernandina and Mosquera, in the Galapagos Islands, have provided a fauna of 26 ostracod species of which 14 are new. One genus, belonging to the Hemicytheridae, is also new and appears to be endemic to the Islands. From two littoral algal samples collected from Punta Canoa and San Pedro beach, Ecuador, an assemblage of some nine species, four of which are new, is also described. Two ostracods:Touroconcha lapidiscolaandLoxoconcha (Lox‐ocorniculum) lenticuloides, are the only species so far known to be present both in the Galapagos Islands and off the coast of Central and South America. One species:Cytherelloidea praecipuarecorded from off Tobago and Clipperton Islands may be present in the Galapagos but this has not definitely been confirmed. The evolution in the Gulf Coast/Caribbean region of several ostracods and their subsequent dispersal westwards is discusse

摘要:

The postcranial skeleton of the reptileGephyrosaurus bridensisis described. The material was extracted from the Lower Jurassic fissure infillings of South Wales and comprises the broken and dissociated bones of many different individuals. The skeleton, like the skull, retains many primitive features which justify the inclusion ofGephyrosauruswithin the Eosuchia. A comparison of the skeleton with that of other genera supports the conclusion thatGephyrosaurusrepresents a separate eosuchian lineage. The skeleton is that of a small, unspecialized terrestrial reptile which could move quickly in pursuit of prey.
