I have great pleasure in sending- the following- additions to my 

 list of Lincolnshire Freshwater Mites, published in ' The 

 Naturalist,' August 1900, pp. 253-5. All the species I mention 

 in this paper have been found in the vicinity of Kirton-in- 

 Lindsey, in District 5 East, of North Lincolnshire, within a 

 short drive of this place, and never more than seven miles 

 away. 



WATER MITES— HYDRACHNID^. 



Atax intermedius (Kcenike). Found parasitic in the gills of 

 freshwater mussels taken from the river Eau in this parish. 

 For a short description of this mite, with figures of the 

 tarsus and genital plates of the female, see Mr. Soar's 

 paper in ' Science Gossip,' June 1900, p. 18. 



Curvipes aduncopalpis (Piersig-). For figure see 4 Science 

 Gossip,' March 1891, p. 295. 



Piona latipes (MuTler). See ' Science Gossip,' July 1900, pp. 

 48-49, for description of this curious and beautiful mite and 

 a figure of the hind leg- of the male.

Arrenurus tricuspidator (Piersig). This mite has not yet, 

 I believe, been figured in any English work, but a figure

 Mites, plate 43, ligure 127.
