“…nov., its diminutive colony size aligns it with a group of small species included within a so-called "E. capillare group" (e.g., Watson 1985;Marques, Mergner et al 2000). That group appears to be morphologically diverse, however, so comparisons were made here with all recognized species of the genus.…”

“…Many of them were founded on sterile specimens or on unreliable characters, and are now considered species inquirendae. Characters accorded particular taxonomic importance include the structure of the gonophores, particularly those of the female, the extent of retrogression of reproductive hydranths, and more recently the complement, distribution, shape, and size of nematocysts (Picard 1951;Watson 1985;Calder , 2010 Bouillon et al 2006;Schuchert 2008b). Also perceived to be helpful in the identification of certain species is the presence or absence of buttons or a continuous band of nematocysts around the gastric column of the hydranth, the presence or absence of nematophores, the prominence of the perisarc groove on the hydranth, and the orientation of nematocysts on the tentacles, whether tending to be parallel or oblique to the tentacular axis (Schuchert 2008b).…”

“…However, all of these species differ from E. bleakneyi in one or more morphological characters. For example, a prominent nematocyst belt, such as that encircling the base of the hydranth in E. bleakneyi, is lacking in all except E. nambuccense and possibly E. antarcticum (Millard 1975;Watson 1985Watson , 2003Hirohito 1988;Marques, Mergner et al 2000;Schuchert 2008b). Moreover, unlike in E. bleakneyi, colonies of E. armatum, E. corrugatum, E. deciduum, and E. terranovae are relatively large and polysiphonic (Millard 1975;Watson 1985;Schuchert 2008b).…”

Two new species of hydroids, Eudendrium bleakneyi and Halecium praeparvum, are described from the Bay of Fundy. Fourteen others, Tubularia acadiae Petersen, 1990, Coryne pusilla Gaertner, 1774, Sarsia lovenii (M. Sars, 1846), Zanclea implexa (Alder, 1856), Corydendrium dispar Kramp, 1935, Rhizogeton fusiformis L. Agassiz, 1862, Bougainvillia muscus (Allman, 1863), Rhizorhagium roseum M. Sars, in G.O. Sars, 1874, Hydractinia symbiolongicarpus Buss & Yund, 1989, Eudendrium vaginatum Allman, 1863, Tiaropsis multicirrata (M. Sars, 1835), Obelia bidentata S.F. Clark, 1875, Halecium marsupiale Bergh, 1887, and Sertularella gigantea Hincks, 1874, are reported, with collection data, for the first time from the bay. All but Coryne pusilla, Rhizorhagium roseum, Eudendrium vaginatum, and Sertularella gigantea are also new to Atlantic Canada, while Zanclea implexa, Corydendrium dispar, and Halecium marsupiale are reported for the first time in the western North Atlantic. Two of those species, Hydractinia symbiolongicarpus and Obelia bidentata, are disjunct in distribution, with core populations occurring in warmer waters to the south of Cape Cod, Massachusetts. Both were discovered in Minas Basin, a hydrographically distinct embayment where surface water temperatures are much warmer during summer than in the perpetually cold lower Bay of Fundy. Rhizorhagium roseum and the subfamily Rhizorhagiinae are transferred from family Bougainvilliidae Lütken, 1850 to Pandeidae Haeckel, 1879. An annotated checklist of hydroids from the Fundy region, based on previously published reports and on new records of species, is added as an appendix. Included in the checklist are 43 species of anthoathecates and 75 species of leptothecates, referable to 30 families and 56 genera. Families with the most species were Sertulariidae (23), Haleciidae (13), Eudendriidae (11), and Obeliidae (10). Biogeographically, the aggregate hydroid fauna of the bay conforms with that occurring in other parts of the Western Atlantic Boreal Region. Halecium permodicum is proposed as a replacement name for Halecium minor Fraser, 1935, an invalid junior homonym of H. minor Pictet, 1893.

The oldest rhynchosaur from Argentina: a Middle Triassic rhynchosaurid from the Chañares Formation (Ischigualasto–Villa Unión Basin, La Rioja Province)

et al. 2013

Rhynchosaurs first appear in the Early Triassic fossil record and flourished during the late Carnian as the dominant members of several assemblages worldwide. In Argentina, the rhynchosaur record is currently restricted to the Ischigualasto Formation of late Carnian-earliest Norian age. Recent fieldwork in the new locality of Brazo del Puma, in the lowermost levels of the Chan ˜ares Formation, yielded three rhynchosaur tooth-bearing bones, which were collected five metres above the contact with the underlying Tarjados Formation. The most complete specimen is the posterior end of the alveolar region of a left dentary. The dentary possesses densely packed tooth rows on the lingual surface and medial half of the occlusal surface, showing longitudinal Zahnreihen. The teeth of the occlusal surface are worn flat and those of the lingual surface are organized in multiple rows, supporting the referral of the specimen to Rhynchosauridae. In addition, the dentary teeth are conical to mesiodistally compressed, resembling the condition observed in hyperodapedontines. The rhynchosaur remains reported here are the oldest collected in Argentina and among the oldest in South America, together with an unnamed form from Brazil. The new rhynchosaur specimens come from levels in which dicynodonts are numerically dominant, whereas cynodonts are considerably less abundant. Accordingly, the specimens reported here bolster faunal differences within the Chan ˜ares Formation and add a new faunal component to this already diverse vertebrate assemblage.
