A new caridean shrimp (Crustacea: Decapoda: Dendrobranchiata) from the Upper Jurassic Solnhofen Lithographic Limestones of Schernfeld (South Germany)
A new genus and species of caridean shrimps, Occultocaris frattigianii nov. gen. et sp., is described from the Upper Jurassic Solnhofen Lithographic Limestones of Schernfeld near Eichstatt (Lower Tithonian, Hybonotum Zone). It differs from other genera of carideans primarily in the armature of the rostrum in combination with the shape of the chelae of the first and second pereiopods.
The genera Longitergite nov. and Bannikovia nov. in the Lower Miocene of N Caucasus (Russia) (Crustacea, Decapoda)
A few specimens of macruran decapod crustaceans from the Apsheronsk Region (N Caucasus, Russia) are described. The specimens were found in the layers of the Maikop Formation, dated back to Lower Miocene. The study of this material brought to the description of the two new genera Longitergite nov. (Infraorder Penaeidea de Haan, 1849, family Penaeidae Rafinesque, 1815) and Bannikovia nov. (Infraorder Caridea Dana, 1852, indeterminate family). Even though the sample is represented only by a few specimens, it plays a particularly important role, since it enriches the previous knowledge about the macruran decapod crustaceans of Miocene of N Caucasus. Moreover, the genus Bannikovia nov. enriches the knowledge about the Miocene carideans, adding to the two forms already known always discovered in N Caucasus. Riassunto I generi Longitergite nov. e Bannikovia nov. nel Miocene inferiore del N. Caucaso (Russia) (Crustacea, Decapoda). Vengono descritti alcuni esemplari di crostacei decapodi macruri provenienti dalla Regione di Apsheronsk (N. Caucaso, Russia). Gli esemplari sono stati rinvenuti negli strati della Formazione di Maikop, datati al Miocene inferiore. Lo studio di questo materiale ha portato alia descrizione dei due nuovi generi Longitergite nov. (Infraordine Penaeidea de Haan, 1849, famiglia Penaeidae Rafinesque, 1815) e Bannikovia nov. (Infraordine Caridea Dana, 1852, famiglia indeterminata). Anche se il campione e limitato a pochi esemplari, riveste una particolare importanza in quanto arricchisce le precedenti conoscenze sui crostacei decapodi macruri del Miocene del N. Caucaso. Inoltre, il genere Bannikovia nov. arricchisce le conoscenze sui caridei marini del Miocene, sommandosi alle due forme gia note, rinvenute sempre nel N. Caucaso.
The Inca Occupation of the South Coast of Peru
like the others, however; it forks into several nearly parallel ravines of which the largest are Huayuri, Rio Grande-Palpa, Ingenio (called Collao in ancient times), Nasca proper (the ancient Caxamarca), Taruga, and Poroma. Due to peculiarities of the local topography, the irrigated areas in Ica and the ravines of Nasca are located inland, at the foot of the mountains, rather than at the mouths of the rivers as is more usual in Peruvian coastal valleys. No sharp natural or cultural boundary separates the valley of Chincha from the valleys of Cafiete (ancient Huarco and Runahuana), Asia, and Mala, the next valleys going up the coast to the northwest. At the other end of the area we are considering, however, there is a sharp break; beyond Yauca the Andean foothills reach out to the sea, natural conditions are quite different, and there are important differences in the archaeological picture as well. The historical sources which mention the south coast are not particularly helpful, except in so far as they provide us with a few dates. To begin with, no chronicler gives an explicit account of the political organization of the south coast at the time it came into contact with the Incas. It can, perhaps, be inferred from Cabello Balboa's statements about common policy toward the Inca invaders that there was some sort of political connection between the valleys of Mala, Cafiete, and Chincha, but the connection need have been no more than a temporary military alliance. Cabello makes no mention at all of Pisco. The valleys of Ica, Nasca, and 125
