There has been great confusion between this and the last 

 species, which, considering their small size and slight dif- 

 ferences, is scarcely to be wondered at. We have given 

 references to the figures which best distinguish the two forms; 

 those of Kaufmann are perhaps the best.

We found this species in a gathering kindly made for us 

 by Mr. Vallentin in " Hayle Kimbra," a large pond on the 

 Lizard. At the time of Mr. Vallentin's visit in Oct. 1905 

 the pond was very nearly dried up and divided into two parts.
