"Anterior part of first segment very finely tesselated, the granules being 

 arranged in irregular longitudinal rows. The head retracts into the posterior 

 part of this segment, whose exterior is a longitudinally striate thin membrane 

 inflated to gibbous barrel shape [Plate 7, Fig. 92]. The line of separation between 

 the parts of this segment is marked by a ring of fine fleshy crenulations. Second 

 and third segments surrounded about the middle by undulate crinkly thin-edged 

 folds [Plate 7, Fig. 92, a, b, c] with five symmetrically placed backward angula- 

 tions in each fold on each side. Parts of these two segments posterior to the 

 folds with as many longitudinal sulci as there are angles in the fold, and longitud- 

 inally striate with fine irregular wavy ridges. Anterior third of second segment 

 finely striate lengthwise. Part of second segment just in front of fold and ante- 

 rior portion of third segment granular." 



"On the fourth and following segments these folds are broken up into series of 

 fleshy tubercles, on both sides of which the surface of the segments is raised into 

 low ridges, which on the anterior segments have a few, and on the posterior seg- 

 ments several, low protuberances. The fourth and following segments more 

 prominently ridged transversely on the dorsal area and longitudinally on the 

 ventral area. A trace of longitudinal striation remains on posterior of three 

 ridges (on each segment just described) or protuberances representing it. The 

 fleshy teeth derived from the medium segmental folds largest and most numerous 

 on the middle of lateral area of each segment, where they are heaped up into 

 irregular elevations, with two more prominent points forming a series alongside; 

 these elevations marked off by deep impressions both above and below and be- 

 coming more prominent posteriorly. There are three tubercles above (supra- 

 lateral series) lateral prominences and about five below (infralateral series) on 

 each segment behind the fourth." 



"The fleshy fold is continuous across the dorsal area of fourth segment [Plate 

 7, Fig. 92]; back of this, dorsum of each segment marked by a depressed compara- 

 tively smooth elliptic area. These areas bounded in front by a varying number 

 of thin fleshy teeth and posteriorly by a series of low broad longitudinally striate 

 protuberances. Two of the latter fall into a series down the median line of the 

 segments, on the ninth and tenth of which they become closely approximate, 

 much more prominent, and round pointed. The first of the series (supralateral) 

 of these tubercles above the prominent lateral elevations bounds the dorsa' de- 

 pressions at the sides and stand in a series along the back." 



"Ventral series [Plate 7, Fig. 92] of protuberances marked off from infra- 

 lateral series by a hiatus, by lower and thinner teeth, and by the forward arch- 

 ing of the series. It consists essentially of two stronger lateral teeth with a 

 varying number of less prominent ones between. On the tenth segment the 

 series is shortened and the middle elements are almost lacking. Between these 

 arched series of teeth and posterior ridges on the ventral surface of the segments 

 (which are represented by about four low round protuberances) are depressed 

 areas similar to those of the dorsal surface. These are bounded at sides by
