Proboscis lar^^e, triinerous, with tlircc distinct lips at the tip 

 (PI. 2, Fijr. G); it ari.c. in-n, thr ^,■n^al nf ilu- nr. k ai its 



position it reaches hack to ihv posterior holder of the >.coii(l 

 trunk segment (see PI. J, Fig. 2). In outhnc it is mmmi to he 

 fusiform, but is divided at about its distal third l)v a (h>tinct 

 groove; the basal part does not, however, constitute a (hstinct 

 segment as in pAirycyde. 'J1ie proximal portion expands rather 

 regularly to its outer end, while the distal portion taken by itself 

 is distinctly [)ear-shaped. In cross section, or as viewed from the 

 end (PI. 2, Fig. 6), the proboscis is triangular, the dorsal angle 

 being directed downward as the organ is carried turned back 

 under the body. 



Chelifori (PI. 1, Fig. 3) short, 2-jointe(l,' and armed with a 

 few small, scattered spines. The basal joint, which e.\[)an(ls 

 somewhat distally, is only about as long as the hrea.hh of one 

 of the lateral processes, while the second joint is merely a nniiute 

 rounded knob. No indication could be seen of a former chelate 

 condition, though these organs undoid)tedly possess chela- in the 

 larva. 



Pal{)i (PI. 2, Fig. 11) arising from small lateral processes at 

 the anterior end of the neck; lO-jointed; joints 1 and 2 verv 

 short; joints 3 and 5 about equal in length, and nnieh the loiii:- 

 est of all; the former expands rather gradually distally. while the 



about one third of joint :>: joint (i is still shorter and hends at a 

 right angle to o; joint 7 is ^Iigllllv longer than joint (1. and the 



allel with joint 5, and reach back about two thirds of its length. 

 The first five joints are sparsely armed with small spine>. wiiic-h
