There are several points of correspondence between the present material and Bruces descriptions: cuticle with prominent cervical rings, inconspicuous lateral alae, lip shape, lack of distinct postlabial grooves, the relative proportions of the intestinal caecum and ventricular appendage, and number and arrangement of the caudal papillae. However, the present specimens differ from those re-described by
