How any man in the present state of nomenclature can name varieties in 
his notebooks ‘‘merely for private convenience,” and publish the same 
‘without any desire to add to the number of existing synonyms” is incom- 
prehensible ; it is just by such action that synonyms are made],

Mucous tracks of Limnza stagnalis L.—Whilst on a_photo- 
graphic tramp with my friend, Mr. H. G. Brierley, of Huddersfield, up 
Calder Vale, last bank holiday, we passed along the side of Tag Lock, a 
disused canal connecting two bends of the Calder. The canal is choked 
with common reeds, bur reeds, and water plantain, and Limca stagnalis 
and Planorbis corneus are plentiful. The molluscs, when sought for by Mr. 
Brierley, towards evening a few weeks previously were not to be found, but 
in the bright sunshine they were common enough. The tracks of the 
Limnzea were quite distinct on the lower surface of the water-film, and were 
visible to us as straight paths, six to eight feet long, and half-an-inch wide, 
of whitish iridescent slime. The clear water of the canal ran over a bottom 
darkened with black organic mud, against which the slightest deviations of 
the paths were plainly discernible. Singularly the many tracks ran across 
cach other almost at right angles, and where they crossed there was no inter- 
ruption of the continuity of the mucous secretion. —IITENRY CROWTHER,
