A small V. minor (?) is found at Haslemere (Dist. 8). 

 This familiar and common species is distributed everywhere in the 

 ponds, ditches, and running streams of our county. It is variable in 

 form and great difficulty is experienced in doing more than approxi- 

 mating varieties. This will in some measure explain the absence of 

 locality records.
