Disrri/itii)ii. — liixly is long and slender with segmenta- 

 tion well marked. The rnnit/erx are well separated from 

 one another, and are much longer than broad. The third 

 and fourth pairs are a little closer than any of the preced- 

 ing pairs. The posterior pair are directed somewhat bark- 

 Avard. Each ciiiriger possesses a well marked dorsal tuber- 

 cle at the distal end. 



Cephalon is very slightly expanded in front, and is 

 continued backwards into a long and narrow neck. - Above 

 the base of each chelophore is a small tubercle. A little 

 more than half the distance along the neck occur two 

 prominent lateral '"cervical processes" to which the ovijrers 

 are attached. Just dorsal to these is the om/ar luherr^e, 

 a fairly prominent rounded eminence with visual elements 

 poorly developed and not pigmented. Behind this the 

 neck is slightlv wider than in front. 



Proboscis has the shape of a long oval and possesses a 

 short scape. It is directed downwards.
