afterwards was obtained in Park Loch, near Campbeltown (Can tyre), has 

 now also been obtained in Loch Lomond. It occurred in the shore gather- 

 ing collected between Balmaha and the mouth of the Eudrick Water. In 

 this gathering it was somewhat rare. 



Canthocamptus hirticornis. — This also was obtained in Loch Lomond 

 in nearly the same locality as the last, but at a somewhat later date. C. 

 liirticornis is sometimes observed in water that is more or less brackish. 



Attheyella duthiei. — This Harpactid was described from Shetland 

 specimens, but was subsequently discovered in a shore gathering of 

 Entomostraca from Loch Leven, Kinross. This somewhat rare species 

 was again observed in two of the shore gatherings from Loch Leven 

 collected during the recent investigations, 



Moraria brevipes (G. 0. Sars), which is a somewhat rare species in 

 the lochs of Scotland, was observed in Loch Achray and Loch Doon, but 

 appeared to be scarce in both lochs. 



Maraenobiotus vejdovskii, Mrazek. — This small Moraria-like species 

 was a few years ago added to the British fauna from specimens obtained 

 in Loch Vennachar. I have now to record its occurrence in another 

 Scottish loch — viz., in Loch Doon. It was observed in a shore gathering 

 from that loch collected in December 1897. In Maruenobiotus the 

 mandible-palp is almost obsolete, and in this respect it differs both from 

 Mesochra and Moraria, which possess a moderately developed one- 

 branched mandible-palp. 



The species that compose the genus Canthocamptus appear to be a 

 rather heterogeneous lot, and there seems to be good reason for not only 

 removing some of them to Dr. Brady's genus Attheyella, but for a still 

 further subdivision of the group. 



The Ostracoda. — A few of the Ostracods obtained during the recent 

 investigations may now be referred to : — 



Cypria exsculpta, Fischer. — This, which is one of a small group of 

 laterally compressed Ostracods, differs from the more common Cypria 

 compressa by having its shell ornamented with fine, close-set striae. 

 Though observed in four of the lochs it is less common than some of the 

 other species. 



Cypris obliqua, Brady. — This fine and distinct species has a moderately 

 wide distribution, but is not very common. It has been obtained in only 

 two of the lochs examined. 



Cypris incongruens, Bamd. — This Ostracod appears to be local and erratic 

 in its distribution, occurring in some places in the greatest abundance, while 

 in localities that appear to be equally favourable not a trace of it is to be 

 found. On one occasion the species was observed in great plenty on the 

 surface of some mud that had collected in the bottom of a large tank 

 situated on the top of a sugar refinery in Greenock. How they got there 

 is a mystery, as the only water that the tank contained was supplied by 

 the clouds. 



Cypris puber a, Miiller. — This is one of the largest, if not the largest, of 

 the British Ostracods. It occurred in only two of the lochs under consider-
