tgo1-1902.] The Entomostraca of Mid-Lothian. 315 
found it there only on one occasion, and have not seen it 
elsewhere. 
In an old quarry near Granton, into which warm water is 
discharged from the ink works, we found numbers of Daphnia 
galeata, and also a young form which corresponds exactly to 
Brady’s Daphnia hamata. The terminal claw of the post- 
abdomen in hamata is furnished with several strong teeth, 
which are absent in D. galeata. Such a difference is commonly 
held to be sufficient to constitute a species, and Mr Scott tells 
us that the so-called Daphnia hamata is almost certainly a 
young form of D. pulex. We hope to make some observa- 
tions on the subject this summer. 
We have found the large old quarry in Ravelston a good 
collecting ground, and our thanks are due to Miss Murray 
Gartshore, who has kindly given us permission to collect there 
as often as we like. The crustacean fauna of the quarry 
differs from that of most localities in the neighbourhood, by 
far the most abundant species being Diaptomus gracilis and 
Bosmina longirostris, The water in the quarry is deep and 
very clear. 
From Craigleith Quarry we obtained a solitary specimen of 
Cypris obliqua, a species which we have not found elsewhere. 
When we first fished in the quarry, some three or four years 
ago, we found hardly anything, except the larvas of some 
aquatic insect; but lately we have obtained ten species of 
crustaceans, and we suppose the water is becoming gradually 
_ populated.

Duddingston, as might be expected, considering the extent 
of water, and the age of the loch, has given us a greater num- 
ber of species than any other locality. We obtained twenty- 
seven in our four visits; but Mr Scott, in his report to the 
Fishery Board on Scottish Inland Waters, gives a list of forty- 
_ three species from Duddingston. Four of our species, Cyclops 
afinis, Ilyocryptus sordidus, Alona guttata, and Alona affinis, 
are not included in Mr Scott’s list. Duddingston is the only 
_ place in Mid-Lothian where we have found Lurycercus lamellatus 
and Alona tenwicaudis ; and our only locality besides the Elf 
Loch for Zlyocryptus sordidus and Alona guttata. 
The old bed of the Almond, near Turnhouse, has given us 
_ Some good catches; we have found there fifteen species in all.
