As described by Willey 1949:442:

Definition as a type: Florida Gulf Coast

Ware characteristics: A coiled ware. Sand-tempered with compact, granular paste core. Core is gray-black; surfaces are usually buff-fired. Very much like Weeden Island Plain.

Decoration:

Technique: Incised lines made in soft clay before firing.

Design: Lines arranged horizontally on vessel, encircling neck or body below rim. Lines vary from faint and sharp to deep and broad. Spacing of lines ranges from 5 mm. to 1 cm. Quite often the incised lines have an "overhanging" or "clapboard" appearance when vewed in profile. (Pl. 32, g, k; pl. 33, j, k; pl. 46, f.)

Distribution: Exterior. Upper portion of vessel.

Form: Mostly collared jars. Rims unmodified.

Geographical range of type: All of Florida Gulf Coast but seems to be more common around Tampa Bay. The type appears as a minority one in all regions and contexts.

Chronological position of type: Weeden Island II and probably Englewood. May extend into Fort Walton Period.

Relationships of type: Closest parallel is Coles Creek Incised, marker type of the Coles Creek Period in southern Louisiana (Ford and Willey, 1939).
