在挪威北方特罗姆瑟附近采集的Ptychocylis属的标本共拍摄了121张照片。对来自相同样品的165个试样进行了详细测量。根据洛里卡的形状来区分尖叶对虾、北极对虾、基曲对虾、圆柱对虾、干加尔对虾、冰川对虾和钝叶对虾是不可行的。一些图示形式与文献中的任何描述都不对应。有1个多变量种被优先命名为钝头原甲，或者必须用洛里卡以外的其他方法来区分该属的种。
A total of 121 photographs was made of specimens in the tintinnid genus Ptychocylis, collected in the vicinity of Tromso, northern Norway. Detailed measurements were undertaken of 165 specimens from the same samples. It is not feasible on the basis of lorica shape to distinguish among P. acuta, P. arctica, P. basicurvata, P. cylindrica, P. drygalskii, P. glacialis and P. obtusa. Some of the illustrated forms do not correspond to any descriptions found in the literature. There is either 1 multivariate species to be named P. obtusa by priority or other means than the lorica must be used to distinguish species in this genus.
