Umbones located anteriorly, with a large, hat-shaped prodissoconch which is characterized by a low conical central base and coarsely frilled brim margin, ca. 260 µm length and 250 µm height. Exterior surface with 7–9 beaded radial ribs crossed by regular commarginal lamellae. Intervals between ribs are broadly concave. Interior margin with a few strongly marked interlocking tubercles restricted to postero-ventral area. Hinge consisting of a large tubercular tooth in the anterior of each valve and numerous perpendicular denticles placed dorsally and interrupted by the ligament, resulting in a row of anterior and posterior denticles. Color translucent white and sparse orange blotches in adults.</p> <p> <b>Remarks.</b> From the ten described philobryid genera, <i>Cratis</i> matches well by exhibiting the strong cap, clear dentition, trigonal ligament pit, dorsal denticles and pinctadoid shape. The sculpture of the <i>EI</i> material, however, is less beaded than in the type species and in most of the congeners. Internally, the posteroventrally 4–5 marked interlocking tubercles are similarly found in <i>Cratis delicata</i> Bergmans, 1970, which, has a very distinct hinge and dentition. The type species <i>C. progressa</i> has similar tubercles also placed anteroventrally, and a much stronger dentition as well as a strong, narrowly beaded sculpture.</p> <p> Nothing known from the Hawaiian Islands resembles this species, and from the nine described Pacific <i>Cratis</i> species, only one merits close comparison, namely, <i>C. kanekoi</i> Hayami & Kase, 1993, from Miyako Island. All other species are at once separated by sculpture and/or stronger dentition and/or missing or additional tubercles.</p> <p> <i>Cratis kanekoi</i> is identical in shape and in sculpture with widely spaced radials and lamellate commarginals. Position and sculpture of the cap are indistinguishable. Internally, the posterodorsal tubercles are very similarly arranged. At first glance the hinges seem to differ in that the tooth socket is placed left or posterior to the large cardinal of the scarce Okinawan material. However, in the numerous <i>EI</i> and <i>SyG</i> material studied both conditions were encountered, with the socket placed left or right of the prominent tubercular tooth. This is consistent with Tevesz’s (1977: 15) observation of high intraspecific variability of the <i>Cratis</i> dentition. Thus, no significant morphological differences to <i>C. kanekoi</i> remain.</p> <p> The <i>EI</i> and <i>SyG</i> material, however, does provide <i>C. kanekoi</i> a new maximum size of 2.77 mm, variability in position of cardinal tooth and socket, as well as an additional feature in adult specimens, that it is occasionally being found with orange blotches. The availability of the material also suggests it has a more common occurrence than originally recorded by Hayami and Kase (1993).</p> <p> <b>Habitat.</b> Apparently common from <i>SyG</i>, but less so on <i>EI</i>, in sand, from 20 m.</p> <p> <b>Distribution.</b> <i>Cratis kanekoi</i> was originally described from Okinawa, but has been recorded from the Society Islands and the Tuamotu Archipelago as well. Easter and Salas y Gómez Islands are now considered a range extension— <b>E4</b>.</p>Published as part of <i>Raines, Bret & Huber, Markus, 2012, 3217, pp. 1-106 in Zootaxa 3217</i> on page 2

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
