long ago, but I was unable to decide on the values of 

 certain forms, which increased acquaintance with Tardigrada 

 in general enables me now to do. 



There are 50 species recorded in this paper, being an 

 increase of 9 since 1907. As 2 species have been 

 deleted, there have been really I i names added. Two 

 of these are new species, i has been already recorded as a 

 variety, and 8 are new Scottish records. The identifica- 

 tion of 5 of the species is still open to doubt, owing to 

 incomplete information on certain points.
