CONULARIDA – Descriptions from Walcott, 1875 and Foerste, 1928.
Conularia quadrata Walcott, 1876, p. 93.
Description: Slender, pyramidal, and quadrate. Angles are sulcate. Surface marked by oblique transverse ridges that alternate upon opposite sides of a central longitudinal ridge. The transverse ridges are sharp near the apex, growing broader at the mouth, toward which they incline. Each side is slightly depressed along the central ridge.

Description: Metaconularia grandulata? differs from Metaconularia papillata in that both the vertical and the transverse rows of papillae are more numerous and the papillae tend to be elongated in the vertical direction.
Metaconularia papillata (Hall, 1847). Foerste, 1928, p. 107, pl. 29, fig. 1;. Sinclair, 1940, p. 108, pl. 2, fig, 1; Van Iten, 1992a, p. 342; Van Iten, 1992b, p. 361.
Conularia papillata Hall, 1847, p. 223, pl. 59, fig. 3a-3b.
Description: The shell looks like it consisted of a tough chitinous material and the four angles of the shell are occupied by an impressed groove. Along the middle of each face is a distinct narrow groove, on each side of which there is an additional impressed groove locating the position of the septum in the interior of the shell. The surface of the shell is marked by minute papillae arranged in vertical and transverse rows crossing each other at right angles. The general surface of the specimen is flat, and not raised into distinct transverse ridges alternating with grooves, as in a typical Conularia.
