种Tintinnopsis斯坦，发生在沿海沃茨的西南荷兰，图和描述。几乎所有的洛里卡特征都有很大的差异，特别是某些物种的背口部分的形状（T. beroidea Stein）。洛里卡的口径变异较小，经鉴定有7种类型：T. baltica Brandt，T. beroidea Stein，T. campanula（Ehrbg）D. fimbriata Meunier、毛叶藓T. lobiancoi Dallas，T.涡轮穆尼尔。有些种类的甲极易变，特别是T. beroidea，而T. cylindrica和T.菌毛是恒定的。在当地人群中观察到非常强烈的个体差异。因此，从稀疏的材料中描述新种是不合理的。对于描述性的工作，特别是关于浅海的锡壳类，提倡研究大量的标本。
Species of Tintinnopsis Stein, occurring in the coastal waters of the SW Netherlands, are figured and described. Nearly all lorica characters varied considerably, particularly the shape of the aboral portion of some species (T. beroidea Stein). The oral diameter of the lorica varied much less. The many forms were identified as 7 spp: T. baltica Brandt, T. beroidea Stein, T. campanula (Ehrbg) Daday, T. fimbriata Meunier, T. lobiancoi Daday, T. turbo Muenier. Loricae of some species were extremely variable, notable those of T. beroidea, while T. cylindrica and T. fimbriata were constant. Very strong individual variation was noted in local populations. Therefore it is not justified to describe new species from sparse material. For descriptive work, especially on neritic tintinnids, investigations of a great number of specimens is advocated.
