Trunk rather compact; lateral processes separated by narrow intervals, last two pairs by almost their own diameter. Transverse body ridges prominent, each with a narrow, conical median projection. Cephalic segment with a blunt rounded lobe external to the inser- tion of each chelophore; hardly as long as the sum of the two succeeding segments. Ocular tubercle rather higher than wide, stout, rounded at apex; eyes set near apex, of small size but the anterior rather larger than the posterior pair (Fig. 51). Proboscis longer than trunk, straight, slender; widest in proximal third narrowing to almost half this width anteriorly; ap- parently suited for probing. Abdomen rather long but much elevated, so that it does not reach beyond the distal end of the fourth lateral Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - col
