Mueller) Focke) occurs in quantity in one part of the Isle of Man and is known also from two counties in the far north of Ireland, where it may well prove to be widespread. R. angobegicus D. E. Alien & H. Vannerom, sp. novo (ser. Anisacanthi H. E. Weber), is widespread in the west half of Belgium and locally common in one district of Hampshire by the southeast shore of Southampton Water. R. davisii D. E . Allen, sp. novo (ser. Rhamnifolii (Bab.) Focke) , confined to heaths and locally abundant in south-east Dorset, is known elsewhere in Wessex as well as in Pembroke and Jersey. R. sempernitens D. E. AlIen & L. J. Margetts, sp. novo (ser. Radula (Focke) Focke), is widely distributed in Devon and known from one wood in the Cotentin Peninsula, dep. Manche, France. R. venetorum D . E . Allen , sp. novo (ser. Hystrix Focke) , is locally abundant in Brittany and neighbouring parts of north-west France and in the largest of the Isles of Scilly; isolated patches have also been found in four counties in the far south of the English mainland."
