Cam pace* oblong, oval; extremities rounded., the posterior somewhat narrowed: 

 dorsal ma .-in gently arched; ventral slightly sinuated. Seen from above, the carapace 

 is broadly ovate, pointed in front and rounded behind ; the greatest diameter a little 

 behind the middle. End view suborbicular, somewhat angular above. The surface is 

 rather thickly covered with long, fine hairs, and almost always bears patches of a dull 

 iurfuraccous character, apparently a desquamating epidermis; it is also superficially 

 marked, more especially in young specimens, with a wrinkled or reticulated pattern. 

 The colour is of variable shades of brown, with irregular transparent patches. Lucid 

 spots about seven in number, long and narrow, and arranged obliquely across the valve. 

 The abdominal rami are long and very slender, the terminal claws long and slender, sub- 

 equal ; marginal setae very near the apices of the rami.

This is one of the commonest of British species, occurring abundantly in ponds and 



stagnant water. I do not, however, remember ever to have met with it in lakes or 

 streams. 



The form described by me under the name of O. oblonga appears to be nothing more 

 tl.an an unusually elongated variety of this species. MuUer's figures and description of 

 c. p,om not hitherto identified by authors with the present species, are so very charac- 

 WIWIO, that I feel little doubt that his specific name should be adopted on the ground 



priority. His figure is certainly somewhat too small in comparison with some other 

 s <.c.es ; but much stress cannot be laid upon a difference of this kind. Yet, as the name
