NELSON : ON THE LIMNiEIDifi. 265 



molluscan life, amongst which were rather fine examples of 

 Limncea peregra, also Planorbis carinatus, Planorbis vortex, 

 Planorbis corneus, and Physa fontinalis. Close to this place is 

 a village called Hive ; it is indeed so close as to be almost a 

 continuation of it. In a ditch quite in the village we obtained 

 examples of Limncea peregra and Planorbis spirorbis. 



We now entered upon a number of cross roads that were 

 very rough, and trudged along some distance before again 

 sighting water ; at length we came to a ditch near Ousethorpe, 

 and after spending sometime in search we found we had obtained 

 examples of Limncea peregra, L. palustris, Physa fontinalis, 

 Planorbis vortex, and P. marginatus. One specimen of Z. 

 palustris had the body whorl of a somewhat unusual size. 



In a pond near Sleights House we examined the duckweed 

 {LeiJina minor) and found a good number oi Planorbis nautileus, 

 but the process being a very tedious one we soon tired of it. 

 The only shell we obtained here besides was Planorbis spirorbis. 



Again going some distance we got into a lane rejoicing in 

 the easy-going name of Featherbed lane. Here we went along 

 very smoothly for some distance until we neared Yokegate ; 

 here in a ditch we got specimens of Limncea peregra, L. 

 palustris, Physa hypnorum and Planorbis spirorbis. The surface 

 of the Lane now became very uneven, and was not much easier 

 to walk on than a featherbed would be, but we plodded along, 

 keeping a sharp look out for any water to search, as much for 

 an excuse to stop as to get shells. Spying a pond close to the 

 hedge, but of course at the other side, we got through and found 

 examples of Planorbis corneus, P. marginatus, Limncea 

 peregra, L. stagnalis, and L. palustris, and in the ditch which 

 was connected with the pond were numerous examples of 

 Planorbis spirorbis, Physa hypnorum, and Limncea glabra, but I 

 do not think that a single example of the last three was found 

 in the pond. The Physa hypnorum were rather fine and looked 

 very pretty as they floated in the water with their dark blue- 

 black bodies contrasting pleasingly with the bright amber colour
