New marine shells from Panama

Descriptions of New Bats from Panama

In its studies of tropical diseases, the Gorgas Memorial Laboratory of Panama is conducting a mammal surve3r of the Republic. The work in 1959 centered on the headwaters of the Rio Pucro, near Cerro Tacarcuna, Province of Darien, eastern Panama. Among the mammals collected on the Rio Pucro were 43 species of bats, all caught in mist nets. Many of these species had not been taken previously in C...

New Earlymiocene Protoceratids (mammalia, Artiodactyla) from Panama

Although Cenozoic protoceratid artiodactyls are known from throughout North America, species referred to the Miocene protoceratine Paratoceras are restricted to subtropical areas of the Gulf Coast and southern Mexico and tropical areas of Panama. Newly discovered fossils from the late Arikareean Lirio Norte Local Fauna, Panama Canal basin, include partial dentitions of a protoceratid remarkably...

Uranium in aragonitic marine bivalve shells

a r t i c l e i n f o Uranium concentrations in foraminiferal and coral skeletons track oceanic [CO 3 2 − ] and can be useful as a proxy of ocean acidification, but this pH proxy is yet to be investigated in bivalves. Two Saxidomus giganteus shells from the industrialized Puget Sound (WA, USA) and one from the more pristine Kodiak Island (AK, USA) were sampled through ontogeny for U/Ca using la...

A New Species of Pelidnota (coleoptera: Scarabaeidae: Rutelinae) from Panama

A new species of toad (Bufonidae: Incilius) from central Panama

We describe Incilius karenlipsae sp. nov., a new species of toad known from a single locality in the Cordillera de Talamanca of central Panama. We describe this species based on a single individual of perhaps what is now an extinct species. We present mitochondrial sequence data from cyt b (675 base-pairs, bp) and 16S (566 bp) to infer its phylogenetic placement among other bufonids. The new sp...
