Mollusca. — The district being chiefly on peat, sand, and clay, is not good for 
terrestrial mollusca, but the canal and numerous ditches are rich in aquatic forms.

and first week in May, we noted the following Mollusca in the ditches near 
Thorne : — Limnaea pereger, L. pahistris, L. truncaticla, L. stagtialis, L. glabra, 
Planorbis corneus, P. albus, P. carinalus, P. vortex, P. cojitorius, Physa 
fotUinalis, P. hypnorum, Bythinia tentaculata, B. leachi. 
ENTOMOLOGY. — The Entomological Section will be officially represented^ 
Mr. Corbett writes : — 
Lepidoptera- — It would be useless to attempt a list of species occurring in so 
rich a locality ; but a few of the more local species likely to be found are

filipendiilae, Bombyx callwiae, Saturnia caupmi, Hyria atiroraria, Fidonia
