The tibia, or antepenultimate articulation of 

 the legs, seems to be the longest, although it 

 does not appear so in all the figures. This has 

 arisen, partly from the foreshortening, and 

 partly from the difficulty of drawing an animal 

 in motion, with the assistance of the micro- 

 scope. I had intended to review the figures, 

 with the animals, before publication; but the 

 season became too far advanced to admit of it. 

 I think I have succeeded in getting the propor- 

 tions very nearly in figure 8, which, with the 

 details, are by myself. The remaining figures 

 are by Miss Lawson. There is a discrepancy 

 between the position of the coxae, in figures 2 

 and 4 of which the latter is probably nearest 

 the truth. 



I have seen several other species (as well as 

 several of the allied family Acaridee) which I 

 intend to investigate hereafter.
