Established Population

Fourteen specimens of the mooneye (Hiodon tergisus) were collected from the North Saskatchewan and Red Deer rivers in central Alberta, and are first records of this species from these rivers, representing a considerable westward extension of its known range. There appears to be an established population in the Red Deer River, where 13 of 35 Hiodon specimens examined were H. tergisus, the remainder being goldeye (H. alosoides). Only one of fifty-five Hiodon specimens examined from the North Saskatchewan River was H. tergisus.

First Time

Abstract Several species new to the area were collected while monitoring Dutch marine waters using a dredge. The varunid crab Asthenognathus atlanticus Monod, 1933 was recorded for the first time in the North Sea. Until 2008, this relatively rare crab was known from the west coast of Africa and the western Mediterranean to northern Brittany in the north. In recent years, its distribution range has expanded, as indicated by records from the Bay of the Seine and the area around Dieppe-Le Tréport. Our finding from Brown Bank (southern North Sea) indicates a further, northward expansion of its distribution range. We list the hosts with which the crab is associated. Earlier arguments for climate change as an explanation for the northward range expansion are supported.

Mesopelagic Species

The capture of the cornich blackfish, Schedophilus medusophagus, larvae from the Adriatic Sea represents an easterly extension in range of this species, and the first larval record in Adriatic waters.Schedophilus medusophagus Cocco, 1839, is a mesopelagic species from temperate waters of the north-eastern and north-western Atlantic and the western Mediterranean (Bini, 1968; Tortonese, 1975; Haedrich, 1986). The first record of this fish from the Adriatic Sea was reported in 1880 according to Ninni (1912). The second record was during the invasion of medusae Pelagia noctiluca (Malej, 1982; Rottini-Sandrini & Stravisi, 1982; Vučetić, 1982,1983) in Pelješac channel near the town of Korčula-island Koršula (central Adriatic) in 1982 (Onofri, 1986). Ten juvenile specimens, from 10·0 to 20·0cm total length (TL), were collected with medusae at 2m depth. This record Onofri (1986) connected with the ingression of inter-median waters (50–100 m) in the central Adriatic influenced the increase of salinity and temperature in 1982. Jardas (1996) noted that S. medusophagus is a very rare species in the Adriatic Sea.

New Material

New aulacopleuroidean trilobites from the Lochkovian of Oklahoma include the otarionine Cyphaspis carrolli new species from the Haragan Formation, and the brachymetopid Cordania wessmani new species from the overlying Bois d'Arc Formation. Cyphaspis carrolli is the first record of the genus from the North American Devonian. It is a highly plesiomorphic species, dissimilar to contemporaries from Europe, but closely related to Silurian species from Northern Laurentia and England. Cordania wessmani had previously been interpreted as a possible sexual dimorph of Cordania falcata Whittington, 1960, but new material and information shows that the forms occur separately with no stratigraphic overlap. New information on trilobite occurrence in the Haragan and Bois d'Arc Formations does not support previous hypotheses of trilobite sexual dimorphism, but rather indicates the presence of distinct, stratigraphically successive faunas.
