 Banda Sea.

Description. — Body is long and slender with segmenta- 

 tion well marked. The crurigers are' well separated from 

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

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

 ing pairs. The posterior joair are directed somewhat back- 

 ward. Each cruriger possesses a well marked dorsal tuber- 

 cle at the distal end. 



Gephalon 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 o" ' ^ers 

 are attached. Just doTsal to these is the ocular tuherde, 

 a fairly prominent rounded eminence with visual elements 

 poorly developed and not pigmented. Behind this the 

 neck is slightly wider than in front. 



Proboscis has the shape of a long oval and possesses a 

 short scape. It is directed downwards.
