Il6 JOURNAL OF CONCHOLOGY. 



Showing the living specimens to the party who had kept 

 some of the Hving Testacella, as mentioned above, he did not 

 think they were the same ; — his were a brighter orange, and 

 their form somewhat different. The shells I was shown are 

 certainly larger and look different. The two localities referred 

 to (Gartland Place and Kilnside) although in the suburbs are 

 on the same side of Paisley and not very far apart.

(Read before the Conchological Societ3', April 3rd, i8Sg.) 



Sphserium corneum. — Very common in all the canals and 

 ditches around Derby, and certainly one of our commonest 

 shells. 



S. rivicola. — Occurs very commonly in the canal between 

 Shardlon and Chellaston. 



S. ovale. — I found one specimen in canal near Sawley at the 

 junction with the river Trent. 



S. lacustre. — Found sparingly in the above localities ; also in 

 canal near Ambergate. 



Pisidium amnicum. — Seems pretty well distributed through- 

 out the district, but the best and largest specimens have 

 been found in canal between Cromford and Ambergate. 



P. fontinale. — The only place I have found this up to the 

 present time is the River Wye, at Monsal Dale, at the 

 mouth of a small tributary.
