Clark 1977). The latter species was reported for the first time to the Azores by Carpenter (1883b, 1884) based on the material collected by H.M.S. <i>Challenger</i> (sta 76: 38°11’N, 27°09’W, 1,645 m). At the time, Carpenter (1883b) attributed deviations from the typical <i>R</i>. <i>rawsonii</i> observed in the Azorean material to water temperature differences. Following the previous author, Koehler (1909) identified <i>Princesse Alice</i> ’s material from the Azores as <i>R</i>. <i>rawsonii</i>, though observing that the cruise material was quite close to the specimens described by Perrier (1883b) as <i>D. parfaiti</i>. On the redescription of the later species, A.M. Clark (1977) re-examined the material from the Azores collected by H.M.S. <i>Challenger</i> and placed it under <i>D. parfaiti</i> (an East Atlantic species). Without material of the Caribbean species for comparison and based on the historical bibliography, A.M. Clark concluded that <i>D</i>. <i>parfaiti</i> was distinguished by the conical shape of the calyx, by the indistinct or faint sutures between the ossicles in the calyx and by the presence of an abrupt constriction across the radials. Recently, Mironov <i>et al</i>. (2014) remarked that Carpenter (1884) could have been correct in considering the species conspecific, but unfortunately did not give any further details. Regardless, the reports of <i>D. rawsonii</i> to the archipelago were based on the assumption that this species was conspecific with <i>D. parfaiti</i>, thus are considered herein to be erroneous. Additionally, during two dives made by the bathyscaphe <i>Archimède</i> north of S„o Miguel and West of Santa Maria, Pérès (1992) observed stalked crinoids that he believed to be <i>D</i>. <i>rawsonii</i> (= <i>Rhizocrinus rawsoni</i>), which were quite abundant at depths 2,630 and 2,950 m.</p>Published as part of <i>Madeira, Patrícia, Kroh, Andreas, Cordeiro, Ricardo, De, António M., Martins, Frias & Ávila, Sérgio P., 2019, The Echinoderm Fauna of the Azores (NE Atlantic Ocean), pp. 1-231 in Zootaxa 4639 (1)</i> on page 17, DOI: 10.11646/zootaxa.4639.1, <a href="http://zenodo.org/record/3342161">http://zenodo.org/record/3342161</a>

M 48 / 1343: 1 Ψ (ZSM 20020019). M 48 / 1347: 1 ɗ (ZSM 20043076). Additional Material. 1 Ψ (ZSM 20043140), FS "Meteor", station M 3 / 24, Agassiz trawl 2, 42° 26.8 ' N, 14 °49.0' W to 42 ° 40.9 ' N, 14 ° 49.2 ' W, 5270 m, Agassiz trawl, 11 Mar, 1966, det. C.G. Ahearn (USNM), 2004. Description. The specimens range from 76 to 100 mm in length and 24 to 54 mm in width. The body is more or less cylindrical with rounded anterior and posterior ends, of a dirtywhite colour (preserved) and without encrusting foreign bodies. Mouth ventral, encompassed by 20 prominent brown tentacles, which often are retracted and thus difficult to make out. The anus is ventral in position, enclosed in an inconspicuous pygal furrow. Filiform tube feet, lacking a sucking disc, are found sparsely scattered on the ventral side (often visible as small brown spots) but could not be detected dorsally. The body wall is thick and rugose. The calcareous ring is prominent. Longitudinal muscles are flat and wide. There is a single ventral polian vesicle. The gonad consists of a tuft of branching tubules on both sides of the dorsal mesentery. The intestine forms a large loop, and the respiratory trees originate with a common trunk from the right side of the cloaca. Calcareous deposits are scarce. Isolated deposits are present in the tentacles, which are irregularly rodlike, sometimes bent, often branching and with a tendency to form an irregular network, resulting in few to several perforations (Fig. 9 A). No deposits could be detected in the body wall, in the tube feet, in the gonads nor in the respiratory trees. Remarks. In an longneeded and extensive review of the pygalfurrowed Synallactidae (O'Loughlin & Ahearn 2005) all hitherto known species as well as several new species are described, and detailed information is presented, including their synonymy and distribution. Molpadiodemas atlanticus differs from its congeners by a combination of the following characters (O'Loughlin & Ahearn 2005): body large and saclike; even cover of tube feet, frequently inconspicuous; frequent presence of large, irregular, open meshlike gonad ossicles. The two Angola Basin specimens are assigned to M. atlanticus, although they lack the characteristic calcareous deposits in the gonad. Also the third specimen investigated (see additional material), which was determined by C.G. Ahearn in 2004 as belonging to this species, lacks calcareous deposits in the gonad. According to O'Loughlin and Ahearn (2005: p. 153) the lack of calcareous deposits in tentacles or gonads is not uncommon: "…ossicles frequently abundant in tentacles and gonads, sometimes rare or absent;…". But based on the body form (large and saclike), the inconspicuous tube feet and the overall resemblance of the Angola Basin specimens with the specimen determined by C.G. Ahearn, the author is convinced, that the specimens are conspecific. Distribution.

Collecting and using data on forest soils
No full textForest managers and decision-makers require more knowledge of forest soils and better references for understanding soil functioning. At REGEFOR 2013, the “Collecting and using data on forest soils” workshop identified a large under-exploited source of data in development organizations and research laboratories. Software was available for making these resources easier to discover and accessible via Internet. As the data is scattered and the data sets are not harmonized, much remains to be done to enable this data to be used (eg: incorporation into databases, production of metadata and common semantic standards, clarification of ownership rights, data transfer protocols between applications). The workshop also discussed ways of improving coordination between the production and management of data, in particular considering the advantages and limitations of centralization within a single information system

Type locality: Gulf of Mexico (24°33’N, 84°23’W). See: Halpern (1972); A.M. Clark & Downey (1992). Occurrence: Atlantic, in the west from off New York, south to the Gulf of Mexico (Halpern 1972), in the east from the Rockall Trough (Gage et al. 1983) to the Gulf of Guinea (Sibuet 1975), including the Azores and Cape Verde archipelagos (Koehler 1909). Depth: 1,058 –4,825 m (Halpern 1972); AZO: 2,954 –4,261 m (Koehler 1909, Dilman 2008). Habitat: soft substrates (ooze; Gage et al. 1983). Larval stage: lecithotrophic (McEdward & Miner 2001). Remarks: Paragonaster subtilis is a highly variably species and was described in the literature under several names (see A.M. Clark & Downey 1992). For example, Perrier (1885c, 1894) described Paragonaster elongatus (= Pentagonaster elongatus) based on material collected by Talisman at the same station in the Azores (sta 131, 1883: 38°38’00”N, 25°05’46”W, 2,995 m) where the same author recorded also P. subtilis. At the time, Perrier remarked that the former might represent just a variety of later species. Halpern (1972) re-examined the type material including that of P. elongatus from the Azores and synonymized the two species.Published as part of Madeira, Patrícia, Kroh, Andreas, Cordeiro, Ricardo, De, António M., Martins, Frias & Ávila, Sérgio P., 2019, The Echinoderm Fauna of the Azores (NE Atlantic Ocean), pp. 1-231 in Zootaxa 4639 (1) on page 83, DOI: 10.11646/zootaxa.4639.1, http://zenodo.org/record/334216
