The anterior end of the cephalic shield is blunt and quadrangular. The cephalic shield is roughly rectangular and terminates posteriorly with a rounded edge. No upturned papilla was observed on the end of the cephalic shield. The posterior shield is slightly rounded anteriorly and terminates in a medial elongate, digitiform posterior projection that is well-elevated from the base of the shield. This appendage is rounded at the apex and is often held upright in actively crawling individuals. The posterior end of the posterior shield is much lower that the area with the projection and two relatively flat lateral posterior lobes are short and simply rounded. The parapodia are relatively short, leaving most of the cephalic and posterior shields visible. The gill is simply plicate consisting of 12 primary folds and is situated ventrally on the right posterior end of the animal.</paragraph>

There is a membranous periostracum that is slightly more extensive anteriorly than the calcified portion. The area at the base of the shell near the protoconch is more thickly calcified that the rest of the shell.

: The buccal mass is large, highly muscularized and slightly elongate posteriorly and occupies the body cavity for the entire length of the cephalic shield. The buccal bulb entirely lacks any vestige of a radula. There is a large ventral oral gland and a smaller dorsal oral gland. At the posterior end of the buccal mass, near the junction with the crop, is a pair of elongate salivary glands. The crop is large and saccate, wider than the buccal bulb. The crop narrows posteriorly and enters the digestive gland. The intestine emerges from the right side of the digestive gland and terminates near the posterior end of the body near the base of the gill.

): The circumesophageal nerve ring consists of paired cerebral, pedal and pleural ganglia and a single supraintestinal ganglion on the right side. The cerebral and pedal commissures are both elongate with well-separated respective ganglia. Immediately adjacent and posterior to the right pleural ganglion is the supraintestinal ganglion. From its posterior end is the right branch of the visceral loop and the osphradial nerve. The two lateral branches of the visceral loop join posteriorly at the posterior ganglia. The left visceral loop enters the subintestinal ganglion, whereas the right lateral nerve enters the visceral ganglion. The visceral ganglion is larger than the subintestinal ganglion. From the visceral ganglion is the genital nerve, which has a distinct genital ganglion. The buccal ganglia can be seen near the middle of the ventral surface of the buccal mas and are somewhat separated from each other.

). From the large ovotestis, which is intermingled with the digestive gland, emerges the convoluted ampulla. The ampulla narrows into the hermaphroditic duct, which curves around the receptaculum seminis and enters the short, coiled albumen and membrane glands by means of a single duct. The larger mucous gland is bilobed with a massive primary lobe and smaller secondary one. The outer margins of both lobes bear a rounded margin with numerous tooth-shaped lobes. The hermaphroditic duct then joins the duct of the receptaculum seminis and continues to the genital atrium, where it joins the duct of the bursa copulatrix. The bursa is large and spherical. Its duct is narrow where it joins the bursa and widens until its widest portion at the genital atrium. The genital atrium is large and muscular. The atrium also has a lobate vestibular gland situated on its ventral surface. From the genital atrium the open, ciliated sperm groove leads to the cephalic penis. The penis (
