从广泛的地理区域收集的材料中研究了安大略的枝角类。在244个湖泊和33个池塘中采集了标本，其中有些采集了不止一次。本文描述了一种用于本研究的枝角类染色永久标本的制作方法。根据对这些材料的研究，我们提出了Daphnia pulicariaForbes作为北美区系的同义词。普通湖沼种的划分比较令人满意。记录了一个迄今未描述的水蚤种。此外，还对Diaphanosoma属、Ceriodaphnia属、Eubosmina属和Bosmina属的种类作了系统的记述。这使得从安大略记录的物种达到78种; 26种是首次从安大略记录的。虽然目前已知的湖沼物种可能代表了一个完整的列表，但许多沿岸的形式到目前为止肯定还没有记录。讨论了物种的相对频率和优势度。
The Cladocera of Ontario were studied from material collected over a wide geographical area. In all 244 lakes and 33 ponds were sampled, some of them more than once.A method for making stained permanent preparations of Cladocera used in our study is described.The genusDaphniais richly represented. Based on a study of this material we have raisedDaphnia pulicariaForbes from synonymy in the North American fauna. The common limnetic species have been demarcated more satisfactorily. A hitherto undescribedDaphniaspecies was recorded. Some systematic notes are also included on species of the generaDiaphanosoma,Ceriodaphnia,Eubosmina, andBosmina.Seventy species of Cladocera were recorded in the present study. This brings the species recorded from Ontario to 78 species; 26 species are recorded from Ontario for the first time. While the limnetic species presently known probably represent a complete list many littoral forms have certainly not been recorded so far.The distribution of the various species in the different parts of Ontario is given. The relative frequency and dominance of species is discussed.
