A diverse selachian fauna was collected from the Island Creek Member of the Peedee Formation at Castle Hayne, New Hanover County, North Carolina, USA. This inner neritic assemblage consists of 23 species from eight orders, 17 families, and 20 genera and includes the new species Ptychotrygon clementsi sp. nov.  The dentition of a few large macrophagous species with large palaeobiogeographical ranges is described. However, the majority of the reported specimens belong to relatively small species that are endemic to the southern regions of the Western Interior Seaway and the Atlantic and Gulf Coastal plains of North America.

AbstractIn midcontinent North America, the Fox Hills Formation (Upper Cretaceous, upper Maastrichtian) preserves the last marine faunas in the central Western Interior Seaway (WIS).Neritoptyx hogansoninew species, a small littoral snail, exhibited allometric change from smooth to corded ornament and rounded to shouldered shape during growth. Specimens preserve a zig-zag pigment pattern that changes to an axial pattern during growth.Neritoptyx hogansoninew species was preyed on by decapod crustaceans, and spent shells were occupied by pagurid crabs. Dead mollusk shells, particularly those ofCrassostrea subtrigonalis(Evans and Shumard, 1857), provided a hard substrate to which they adhered on the Fox Hills tidal flats. This new neritimorph gastropod establishes a paleogeographic and chronostratigraphic proxy for intertidal conditions on the Dakota Isthmus during the late Maastrichtian. Presence of a neritid extends the marine tropical/temperate boundary in the WIS northward to ~44° late Maastrichtian paleolatitude. Late Maastrichtian closure of the isthmus subsequently altered marine heat transfer by interrupting northward flow of tropical currents from the Gulf Coast by as much as 1 to 1.5 million years before the Cretaceous ended.UUID:http://zoobank.org/3ba56c07-fcca-4925-a2f0-df663fc3a06b

Seven new species of Graphidaceae are described from the Coastal Plain of southeastern North America: Acanthothecis floridana (Florida, USA), A. leucoxanthoides (North Carolina, USA), A. paucispora (North Carolina, USA), Fissurina alligatorensis (Florida and North Carolina, USA), F. americana (Florida and Georgia, USA), F. ilicicola (Florida and Georgia, USA), and Phaeographis oricola (North Carolina, USA). The ecology and distribution of each species is discussed in the broader context of the imminent need for effective conservation and management strategies to maintain the lichen biodiversity in the region. Color illustrations of all species are provided, as are keys to the genera Acanthothecis and Fissurina in North America north of Mexico.

The eight known species of Agrenia are reviewed and new distributional data are added. Two species groups are suggested for the genus: a bidenticulata-group with a mucronal seta and an agilis-group without a mucronal seta. Four new species of the second group are described from North America: A. falcula, A. parkeri, and A. tarashchukae from forest streams of the Appalachian Mountains in Tennessee, North Carolina, and New York, and A. extrema from glaciers in Washington and Alaska. The head of the maxilla is introduced as a useful character for separation of some species. A key to all species is given.

Three new species of Lumbriculidae from southeastern North America are attributed to Eclipidrilus Eisen. All are small worms (diameter 0.2–0.5 mm), having semi-prosoporous male ducts with the atria in X, and spermathecae in IX. Eclipidrilus breviatriatus n. sp. and E. microthecus n. sp. have crosshatched atrial musculature, similar to some E. (Eclipidrilus) species, but they differ from congeners in having small, compact spermathecal ampullae. Eclipidrilus macphersonae n. sp. has a single, median atrium and spermatheca. The new species have been collected only in Sandhills and Middle Atlantic Coastal Plain streams of North Carolina.

A New Species

Moraria hudsoni n. sp. is described from Trails End Bay in Lake Michigan and Prentiss Bay in Lake Huron, Michigan, USA. The new species differs from its congeners in chaetotaxy, body ornamentation, and other characters. We review published records of members of Moraria from North and Central America; no species is known from South America. Species of this genus have been found in the mountains of southern Mexico, Guatemala, and Honduras, but none of these has been validly described. In North America, eight species have been recorded from Alaska, Canada, and the conterminous USA as far south as North Carolina. We report new geographical records of M. affinis from Virginia, and of both M. cristata and M. virginiana from Maryland and Virginia. We provide a tabular key to aid in identification of the named species of Moraria in North America.

Three New Species

In North America, Paleogene Verrucidae are rarely encountered. Only a single named species has been previously discussed by Zullo & Baum (1979), who provisionally assigned a Palaeocene form from North Carolina to Verruca rocana Steinmann, 1921. Eocene deposits in Washington State (USA) have now yielded two new species from intertidal to shallow water environments: Verruca gailgoedertae sp. nov. from the middle Eocene Crescent/McIntosh transition zone, and Verruca sorrellae sp. nov. from the upper Eocene to lowest Oligocene Gries Ranch and basal Lincoln Creek formations. Both species are characterized by punctate shell plates, and are placed in the lineage of Verruca stroemia (O.F. Müller, 1776). In Alabama, marls from the upper Yazoo Formation (Pachuta and Shubuta Members) have yielded Verruca alabamensis sp. nov., an uncommon deeper water form associated with abundant brachiopods and phosphate deposition. This last species shows no development of punctae and is not related to the lineage that leads directly to Verruca stroemia.

Hundreds of years of botanical exploration in heavily populated and highly accessible eastern North America have not exhausted taxonomic prospects in the region. Here, I describe a new species of Asarum (Aristolochiaceae), Asarum rosei B.T.Sinn, from North Carolina, USA. This species is characterized and contrasted with species in Asarum subgenus Heterotropa section Hexastylis, and a revised artificial taxonomic key to the similar species in the section is provided.

Two New Species

Two new species are here described as segregates from Heteranthera multiflora. Heteranthera missouriensis sp. nov. has 5–13 flowers on an elongate floral axis, lavender to purplish flowers, a smaller perianth with the tube 3–5 mm long and lobes 3–4.5 mm long; it is common in the southern Great Plains of North America. Heteranthera pauciflora sp. nov. has 3–6 flowers on a shortened floral axis, commonly enclosed by the subtending spathe, white to light lavender flowers with the tube 8–10 mm long; it is known from the Atlantic coast from New Jersey to North Carolina. A taxonomic key to all species of the genus in North America, and a modified description of Heteranthera multiflora, are provided.

Memorial Volume

To reflect the nearly 65 years of active research into extinct decapod and thoracican crus - taceans (Pleocyemata, Anomura, Brachyura and Cirripedia) by the late Joe Collins, a varied array of papers on polychelid lobsters, paguroid and galatheoid anomurans, brachyurans and scalpellomorph and balanomorph cirripedes is compiled in the present memorial volume. The material described and illustrated originates from a range of sedimentary strata, of Triassic, Jurassic, Cretaceous and Ceno - zoic age in North America (Washington, Oregon and North Carolina), Caribbean (Cuba), Japan and Europe (England, France, Spain, Italy, Switzerland, Slovenia and the Czech Republic). In all, two new genera (one paguroid and a xanthoid crab) and eight new species (all crabs), are erected in the present issue and named after Joe, as a fitting tribute to a well- respected, self- taught scientist.
