Pleurobrachia pilens (O. F. Muller). DĂźring the past 15 months Pleurobrachia pilens has been taken in small numbers at all seasons in the large tidal lagoon at Shingle Street. The animal is carnivorous and at Shingle Street the chief food appears to be Praunus flexuosus an opossum shrimp occurring in larger numbers there. This crustacean has been found in the enteron of Pleurobrachia on a number of occasions. Orchestia bottae Milne Edwards. On August 2nd, 1958, several sand hoppers (resembling freshwater shrimps) were found amongst damp stones and soil on the margin of Dedham Mill Pool. These proved to be Orchestia bottae (Crustacea Amphipoda). Sand hoppers are typically maritime, and there is a number of British species occurring in various habitats round our coasts. O. bottae is exceptional in that it is an inland species. It is apparently very local in its distribution and only one of the recorded localities in East Anglia is the River Yare at Brundali, Norfolk. Early in September, 1958, more individuals were found at Dedham, on this occasion under damp moss on the lock gates. Further investigations may prove that this species is widespread on the banks of Suffolk rivers.

THE Willows form an important part of our flora and there is hardly a marsh, damp wood, river bank, stream, pond, flooded quarry or waste place where they do not occur. Plantations of various kinds can be seen in all areas. Osiers have been extensively cultivated near Stowmarket and other towns for very many years. However, many of the beds are now much overgrown and neglected since there has been a decline in the demand for baskets and other articles which were formerly made locally in considerable numbers.
