the moss, which to so large an extent now leplaces the water, has, 

 according to Mr. Lawson, been probed to the depth of seventeen 

 feet without touching the rock. With a hand-net I made a 

 careful investigation of all that was left of the loch ; and sometime 

 afterwards, when the gathering I had collected was examined, 

 some fairlv interestinsr results were obtained. It was found that 

 Entomostraca were moderately common in the gathering, though 

 only four species were represented ; it was also found that the 

 species obtained were equally divided between the Copepoda and 

 the Cladocera, and, moreover, that the two Copepods represented 

 two very different groups, viz., the Cyclopidse and the Harpacticidse. 

 One of the Copepods was Cyclops bisetosus, Kehberg, a species 

 that was added to the British fauna a few years ago by Mr. D. J. 

 Scourfield, of Leytonstone, Essex, and has only recently been 

 observed in Scotland. The other Copepod was Moraria Anderson' 

 Smithi, T. and A. Scott, which was first noticed in Scotland in 

 1892, in a gathering of shallow- water Entomostraca from Loch 

 Morar, Inverness-shire. Our success in the examination of that 

 loch was due, partly at least, fco the active interest taken in our 

 work by Mr. Anderson Smith, Ledaig, who was then a member 

 of the Fisherv Board for Scotland. Moraria Anderson-Smiihi, 

 T. and A. Scott, has, since its discovery in Loch Morar, been 

 observed in several other places, and appears to be more or less 

 generally distributed throughout Scotland — it was quite frequent 

 in the gathering from the Garry Loch. The two species of 

 Cladocera obtained in Garry Loch were Chydorus sphcericuSf 

 Mliller, a common and widely-distributed species, and Alona 

 rustica, T. Scott, which appears to be rare. Alona rusfica was 

 described in 1894 from specimens obtained in a collection of 

 Entomostraca sent to me from Shetland, and has been observed 

 in one or two other places since, but is always very scarce. 

 Specimens of water mites, water beetles, and some other creatures 

 were also noticed, and are included in the appended list, so far as 

 they have been identified. 



If the Garry Loch could have been examined towards the end 

 of summer, it is quite possible that other Entomostracan species 

 might have been obtained in it, as we find that dififerent seasons 

 frequently give different results ; and also, if a thorough examina- 

 tion of the debris at the foot of the cliffs and of the more
