318 THE FEESH- WATER LOCHS OF SCOTLAND 
Worms. — Of the various classes which are united under the con- 
venient name of Worms, no one, except the Rotifera, has been studied 
systematically in more than a few lochs. Mr C. H. Martin gave some 
time to the study of the worms of Loch Tay and Loch Lomond, 
and I am indebted to him for the majority of the names in the 
following list. Mr John Hewitt also named a few species from 
Loch Ness and some other lochs. Though Worms do not appear to 
be very numerous in the lochs, no doubt the number (25) recorded 
below is far short of what might be expected from more careful study. 
So little attention has been given to the Worms that it would serve 
no purpose to attempt to trace the distribution. Most of the species 
in the list are only recorded for one or two lochs, but there can be 
no doubt that most of them are in all the lochs.
