The body ia very slender, quite smooth, with very widely separated long lateral 

 processes. Anteriorly it is slightly curved downwards. 



The ( Vplmlon is long and slender, longer than the second and third segments, and 

 expanded distally into two dorsal lotas for the articulation of the chelifori. 



The Ocular tubercle lies immediately in front of the first pair of lateral processes. 

 It is short, merely a tow rounded hump, in fact, bearing four well -developed eyes. 



The Abdomen is very small, directed upwards, and not separated from the trunk 

 by an articulation. It is rather conical and extends but little beyond the trunk, not 

 nearly so far as the posterior lateral processes. 



The segmentation of the trunk is distinct, the joint* occurring immediately In-hind 

 the lateral processes. 



The Proboscis is directed downwards, cylindrical, with a slight swelling al>out 

 the middle of its length ; it is as long as the cephalon, and its extremity is rounded. 



The Chelifori arise above the proboscis, each on a lobe of the cephalon, which is 

 here rather more than twice ita diameter posteriorly. The scape is single-jointed, 

 longer than either the proboscis or the chela. A few delicate seta! are scattered along 

 ita length, and there is an inconspicuous distal fringe. The chela is a little shorter, 

 the palm and dactyli occupying equal halves ; the former is covered with fine seta; 

 which also form a fringe round the lse of the movable finger. The fingers are slender 

 and much curved near the tips. Both are provided with a row of fairly stout teeth of 

 nearly uniform size, rather closely set 



The Palps arise below the chelifori and at the sides of the proboscis ; they arc 

 built on exactly the same plan as in the genus Nymphon (fig. la). The first joint 

 is small and stout, the proportions of the remainder being 8:5:3:4. The second 

 joint is sparingly setose except for a distal fringe ; the other joints l>ecome more 

 and more setose to the last, which is richly supplied. On the outer side they are more 

 abundant than elsewhere. 



The Ovigers are ten-jointed and present in both sexes. (Fig. 1 b.) They arise 

 from very abort but conspicuous processes on the lower side of the cephalon, 

 immediately in front of the first pair of lateral processes. The details of this 

 appendage are as in Nymphon. The first joint is very small, the second is twice the 

 size, and the third, which has a very oblique termination, is a little longer still ; none 

 of these bear setae. The fourth joint is very long, slender, and slightly curved ; it 

 carries a glandular aperture on its outer side al>out a quarter of its length ; all the 

 setae are small ; very few occur except as a distal fringe. The fifth joint is longer still, 

 the longest of the appendage, and its distal half is enlarged in diameter ; it is covered 

 throughout with fine setae. The sixth joint is rather more than half the length of 

 the fifth, slightly curved, and on the outer side of the curve plentifully supplied 

 with fine seta:. Of the four terminal joints the first is little more than half the 

 length of the preceding, the other three are shorter and sub-equal ; very few setae 

 occur, except distally. They carry a single row of denticulate spines (fig. Ic). These
