Named after St. Catherines Island. Originally recognized by Joseph Caldwell in the late 1960s.
Net marking on clay or grog-tempered pottery. The fragments of temper in this type are typically larger than the ones used in other St. Catherines types. The interiors are carelessly smoothed and lumpy. Shell scraping on the interior is also common. Rims are straight or sometimes slightly incurving. Lips are usually squared or rounded. The most common vessel forms are the cylindrical jar and hemispherical bowl. Bases are rounded.
