Few fine test processes may present on the posterior end of the body along with sparse spicules of sponges attached to them, otherwise the surface of the test is smooth. Most specimens have epibionts (probably bryozoans) on the test around siphons.

A). Muscles almost equally developed on both sides of the body. Thick circular muscle fibers are on the body wall around the atrial siphon, and circular muscles on the branchial siphon are limited to the wall of the siphon and do not extend beyond the branchial velum. Eight to ten thin short radial muscles radiating from the branchial siphon, the same number of longer and thicker muscles radiate from the atrial siphon. No muscles crossing intersiphonal area. Rather long parallel transverse muscles form a band on each side of the endostyle and cross the dorsal surface posterior to the atrial siphon.

B). The stigmata are not interrupted, mostly with four coils, and form perfectly rectangular meshes, although several polygonal figures are also present. Typically four, occasionally more radial parastigmatic vessels present on each mesh. Double rows of stigmata are separated by five transverse vessels. Each vessel has 10 or 11 simple papillae on the right side of the body and 9 or 10 on the left, and a dorsal languet displaced slightly to the left from mid-dorsal line.
