 postantennal process (fig. 13^^) evidenced only by pah" of nodules 

 lateral to antenna base, each with several hauiike processes. Female 

 and male postoral process (fig. 13A) spikelike, with broad base, tapered 

 to sharp distal end, outer margm sharply mdented medially. Female

mouth cone (fig. 13^), in same region as adhesion pads of pandarids, 

 some euryphorids and some caligids. Female and male maxilla (fig. 

 14a) 2-segmented, situated lateral and slightly posterior to postoral 

 process, arising from padlike projection. First segment approximately 

 thi'ee-fourths the length of second; second segment elongate, broadest 

 medially, with membrane extending along median posterior surface. 

 Distal end of second segment with 2 setalike processes, mnermost
