dorsal angles of the anal valves. The latter are moderately prominent, 

 much higher than long, scarcely rugose, with a tiny irregular sulcus 

 close to the inner margin. Anal sternite with apex truncate. Stemites 

 with a transverse groove behind the middle. Legs elongate; the 

 ventral surface of the second joint is fleshy, appearing generally exca- 

 vated, and the fifth joint is provided with an angularly produced pad, 

 both structures being found on almost all the legs. 



The legs of the first pair are not unlike those of lysiopetalinus 

 (Fig. 55). The basal joint is a very short ring, curiously excised 

 posteriorly (C), provided with a short tracheal stalk; outwardly a small 

 rounded plate is seen {S), admitted to be all that is left of the sternite, 

 the first joint thus being a coxa. The second joint is still shorter and 

 open externally. The remaining joints of the limb are fused into a 

 short and stout cone, tipped with a hook coiled cephalad and divided 

 on its posterior surface by two superficial transverse sulci, which do 

 not extend on the opposite surface. Legs of the second pair with almost 

 completely atrophied sternite; coxal joint subcylindrical, destitute of 

 basal expansion. The following joints show no particular structures, 

 the telopodite being merely shorter than in the ambulatory legs. Penis 

 small, parallel sided on most of its length, apically divided into a pair 

 of abruptly sharpened cones. 



Peltogonopods (i. e., anterior pair of gonopods. Fig. 56) resembling 

 those of lysiopetalinus. The very short sternal band {S) is fused with 

 the long and flattened tracheal stalks {t). Coxal joint very long (C), 

 gently tapering distally, its apex being pear-shaped and provided with 

 two small hooks directed cephalad. The basal half of its inner edge 

 bears an inconspicuous, short and blunt, retroflexed projection. Apical 

 joint (r) as long as the coxa, fastened to the lateral edge of the latter 

 in a manner that its basal, narrowed end almost reaches the sternal 

 plate, while its distal end exceeds the summit of the coxa by less than 

 one-fourth of its own length. The distal end is shallowly depressed 

 cephalad, with acute outer angle, and is provided with two conspicuous 

 processes, an anterior very long and slender, stake-like process, the 

 sharpened end of which is directed proximally, and an inner erected, 

 slightly curved spine, expanded and toothed in the middle of its length. 



Sternite of gonopods {S, Fig. 57) crescent-shaped, with a narrow 

 median, erected rod thrust between the limbs. The latter are 

 rectangular lamellae, three times as long as broad. Above the very 

 thick base, the anterior surface is abruptly and deeply excavated, and 

 the outer margin is slightly notched, owing to the fact that the 

 distal part of the margin lies over the proximal part instead of standing 

 in a line with it. Such structures bearing evidence to the former 

 existence of a joint, the proximal thickened region (C) has to be looked 

 upon as a coxal ring, while the upper flattened region {T) is equivalent 

 to a telopodite. The latter end with a shallow depression, the outer 

 angle being rounded and the inner bearing two short, erected processes, 

 an anterior hooked and an inner spined process. The presence of a 

 seminal groove could not be ascertained. 



The female structures have been described above. The larval 

 stages are unknown.
