284 The Upper Elf Loch, Braids. [Sess. 



Mr Levick, in his paper, suggests that " their presence should 

 rather be considered as indicative of the general good quality 

 of the water than otherwise, as some of them, at least, are 

 known at home and abroad as the inhabitants of deep clear 

 water only." The large majority of those who used this 

 Birmingham water would doubtless not be aware of what 

 it contained ; while as regards microscopists, the ' Journal of 

 the Eoyal Microscopical Society,' in noticing Mr Levick's 

 paper, remarked that they, at least, would have good reason 

 to rejoice for an abundant supply of these micro-organisms 

 brought to, or rather within, their own door, without the 

 drawbacks of pond-hunting ! 



We now proceed to notice the Entomostraca. Among 

 the forms of this class obtained in the Upper Elf Loch, 

 the Copepoda (or " oar feet " order) are specially interesting. 

 Cyclops vcmalis, for example, which has not yet been recorded 

 for the Edinburgh district, has been found here ; while an- 

 other Cyclops, 0. bicuspidatus, has only been previously re- 

 corded for this district from Duddingston Loch. Up to the 

 present time no fewer than six species of Cyclops have been 

 identified from this small sheet of water. The Canthocampti 

 are also comparatively well represented : they comprise three 

 species of Canthocamptus, one of Attheyella, and one of Moraria. 

 Canthocamptus minutus (Claus), one of the three species 

 referred to, was recorded for the first time in Scotland in the 

 'Annals of Scottish Natural History' for October 1895, from 

 specimens found in Loch Leven, Kinross-shire ; and though it 

 has since been recorded from other localities, the Upper Elf 

 Loch is a distinctly new station for it. Attheyella pygmcea 

 (G. 0. Sars), another of the Copepods from the Upper Elf Loch, 

 has also only in recent years been recognised as a Scottish 

 species. Moraria Anderson-Smithi (T. and A. Scott) was, as a 

 new genus and species, added to our fauna in 1893. It has 

 been observed in several localities in Scotland since that date, 

 but its occurrence in the Upper Elf Loch is the first time it 

 has been noticed in the Edinburgh district. 



With reference to the Cladocera (the order with branched 

 antennae), it may be stated that Daphnia pulex, which was 

 common in the gathering collected on the 9 th of May, was 

 scarce in that collected on the 18th of July: on the other
