last year which was not specially dry. | Many examples of 
L. stagnalis are very small, some measuring only 20 mm. 
although they have the full complement of whorls. Z. 
palustris on the other hand run very large, even to 28 mm. 
and proportionately tumid (they are not, however, the form 
corvus). J have also examples of P. corneus and P. com- 
planatus showing similar growth lines. It may be that 
this peculiarity has always existed in these waters, and that 
my attention was directed to it by the mention of it in the 
“Monograph,” but as I have known of it for years, and 
have not noticed it in these waters before, I think it is ex- 
ceptionally marked this season. 
Paludestrina Jenkinsii. I have suspected this to occur at 
Rye, and have searched many miles of dykes around that 
charming old town in vain. But I came upon a single dead 
specimen of the var. cav/zata in the Military Canal close to 
Hythe. As there are many more miles of dykes at Rye to 
explore it may be found there yet. Baltic timber is still 
landed and stacked there.

Planorbis carinatus Miill. monst. scalariforme.—lI send for exhibi- 
tion at the May meeting, a remarkable scalariform specimen of Planorbzs 
carinatus, taken in the brook which runs through Bradgate Park in the 
Charnwood Forest district, about seven miles from Leicester. Thé spot 
where I found it is at a point where several drains converge and keep back 
the brook, so as to form small lakes, about seven or eight feet deep. During 
the dry summer of 1894, they were cleaned out, and the refuse thrown out 
close to the banks, and it was whilst searching these heaps to see if there 
were any examples of Unzo or Anodon in the lakes that I came across the 
Planorbis. Jt was a dead but perfect shell. Although I searched long, 
both on this and subsequent occasions, amongst the thousands of Planorbis 
bleaching on the refuse heaps I failed to find another specimen showing the 
slightest approach to the scalariform shape. —THos. EDWARDS. (Read before
