The lengths of the syntypes vary between 42 and 60 mm., the anterior diameters between 1-1-5 nim. and the posterior diameters 0-75-1 mm. In one specimen there are 116 segments (last 6 segments regenerating) in another 125 (last 10 segments regenerating) and in the third, 137 segments. The cuticle has a slight yellow-green iridescence. The cUtellum is bright orange in life but pale orange in preserved specimens, otherwise the body is unpigmented. The prostomium is broad and epilobous;

The cUtellum is bright orange in life but pale orange in preserved specimens, otherwise the body is unpigmented. The prostomium is broad and epilobous; the peristomium is shghtly cleft dorsally. The first dorsal pore occurs in the first post-cUtellar, furrow 20/21. The cUteUum is annular, xiii-xix (7 segments) and the body wall of segment xiii not so intensively pigmented as the remainder of the clitellum. At both ends of the clitellum the body wall is constricted and the external segmentation is difficult to determine especially anteriorly where much of segment xiii has been Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Museum (Natural History).
