SCOTTISH TARDIGRADA, COLLECTED BY THE LAKE SURVEY. 



667 



EXPLANATION OF PLATES. 



It is desirable that all the figures of the complete animals should be drawn to the same scale, so that the 

 relative sizes can be easily seen, and this has been done in most cases, but so diverse in size are various species 

 that the largest species had to be drawn to a smaller scale in order to include them in the same plates with 

 the smaller ones. 



In Plate III. M. coronifer is drawn to a much smaller scale than the others, and so in Plate IY. 

 M. angusti is only magnified about half as much as the small species in the corners. 



The details are not drawn to any uniform scale.
