| A new alpheid shrimp, Thuylamea camelus gen. nov. & spec. nov., from Dong Hoa, a coastal community of Can Gio district, and northwest of Vung Tau (Cap St. Jacques), Vietnam, is described and illustrated. The new genus appears not to be closely related to any of the previously described genera. It has the postero-dorsal margin of the carapace armed with two high and short crests which are slightly outward inclined and directed backward, and between these crests with a low but distinct conical spine, and an elevated conical boss in the anterior median area slightly behind the anterior margin of the first abdominal somite. |

| The genus Calomys Waterhouse, 1837 is widely distributed within South America, being found in Venezuela, Colombia, Peru, Bolivia, Brazil, Paraguay, Uruguay and Argentina. Specimens of Calomys were collected in Formoso do Araguaia, Tocantins, Brazil. For chromosome characterization standard staining techniques and as G-banding and nucleolar organizer region were used. The karyotype was 2n=46 and AN=66. The X chromosome is a medium metacentric and the Y chromosome a small acrocentric chromosome. Chromosome homologies with other species were observed. Probably, karyotype differences were basically due to Robertsonian rearrangements. |

| The authors describe their experience with an automated immunohistochemical system applied to canine tissue samples. Twenty human cellular markers specific monoclonal and polyclonal antibodies and two different antigen retrieval methods were used in normal and neoplastic breast tissue, as well as skin samples obtained from female dogs of pure and mixed breeds. The antibodies tested were the most frequently used in human and veterinary medicine studies, employed with diagnostic purposes in breast pathology, as well as in cancer research. Most of them may be used to study other normal and abnormal tissues and included cytokeratins, progesterone receptor, c-erbB2, p53, MIB-1, PCNA, EMA, vimentin, desmin, alpha-actin, S-100, pan-cadherin, and E-cadherin.

| Mycena cecidiophila is newly described and illustrated. It grows on knopper galls on the cups of Quercus robur, and was collected from a single site in the Netherlands, Huys ten Donck estate. Although the new species resembles a species of sect. Sacchariferae, it differs in the negative Melzer-reaction on the lamella trama. The new section Cecidiophilae is therefore proposed here to accommodate the new species, characterized by warty elements of the pileipellis, amyloid spores, and absence of pleuro- and cheilocystidia. |

| A new species, Erylus soesti n. sp. is described from SE Brazil. This study is part of an ongoing revision of genus Erylus Gray, 1867 (Mothes, Lerner & Da Silva, 1999; Mothes & Lerner, 1999) and adds a further brazilian species to the genus. This new species can be distinguished by the possession of dichotriaenes, oxeas, and peculiar cushion-like aspidasters with extremely irregular outline, microspined microstrongyles and sphaeroxyasters. A key for identification of brazilian species is provided. |

| A new species of polychaete, Stratiodrilus vilae, epizoic on Parastacus brasiliensis (von Martens, 1869) and P. defossus Faxon, 1898, is described from the State of Rio Grande do Sul, southern Brazil. The new species has one pair of long, anal, conical ventral lobes, one on each side of the anus, claspers in the males, and one pair of tubercles in each of the posterior locomotor appendages; and the jaw apparatus not reaching the limit between the head and the first segment. |

| Based on the specimens collected from Thailand and preserved in AAU, BKF, C, and KYO, Campylandra siamensis (Convallariaceae, Liliaceae s.l.) is newly described in this paper. This species is similar to C. chinensis (Baker) M.N. Tamura, S. Yun Liang & Turland, but differs from it in having numerous sessile leaves, longer white bracts, longer perianth tube and larger pistil. |

| New techniques - called software sensors - issued from the non-linear automatic control field and initially developed for non-linear chemical systems have been applied to a continuous culture of phytoplankton. A software sensor (or 'observer') combines an analytical differential equation based model and partial measurements of the system in order to estimate the non-measured state variables. It filters data and estimates the actual state of living systems, models of which are often rough approximations. The efficiency of this approach is illustrated with a nitrate-limited chemostat experiment with the chlorophyceae Dunaliella tertiolecta performed in a computer controlled fluctuating environment.

| Nonparametric demand analysis uses axioms of revealed preference to test a data set for compatibility with the hypothesis of stable preferences. Previous applications have tested for the presence of structural change using this approach. This paper shows how to include demand shifters such as advertising in the analysis. It is shown that the implied results for changes in tastes depend on restrictions on advertising's effects. |
