A HISTORY OF NORFOLK ARGYOPIDiE The spiders included in this family have eight eyes, situated in two rows, the lateral eyes of both rows being usually adjacent if not in actual contact, while the central eyes form a quadrangle. The tarsal claws are three, often with other supernumerary claws. The web is either an orbicular snare or consists of a sheet of webbing, beneath which the spiders hang and capture the prey as it falls upon the sheet. This immense family includes those usually sepa- rated under the names Epeirida, L'tnyphitday etc. 80. Meta segmentata (Clerck). Cromer, West Runton, Watton and Ormesby (H. W. F.) ; Norwich (F. P.
