During the examination of Rhizopod material collected from different localities in England and Scotland during the past few years, several interesting species have been obtained which I believe have not received previous notice as occurring in this country, and it seems desirable to put them on record. Some of these species are quite common in certain localities, while others, again, are apparently particularly rare, and do not seem to have been observed since they were originally described some years ago. Others, again, though repeatedly observed by their original discoverer, have not been met with by other naturalists. Further and more extended systematic work in this country will probably show that these last are more common than we at present believe.
