NO. 3570 PANDARIDAE — CRESSET 51 



Oral area as in figure 246. A single pair of adhesion pads near base 

 of first antenna. First antenna (fig. 247) 2-segmented. First segment 

 0.77 mm long and bearing 23 stout setae along anterior distal border, 

 all of which are covered with spinules. Fom' smaller finely plumose 

 setae internal to outer spines. Terminal segment 0.42 mm long and 

 bearing 13 naked setae. Second antenna (fig. 249) 3-segmented. 

 Terminal segment in form of a stout, heavily sclerotized claw bearing 

 2 setae, 1 basal and the other median. No adhesion pad associated with 

 this appendage. Mouth tube (fig. 250) about twice as long as basal 

 width with labium extending beyond tip of labrum. Tip of labrum 

 somewhat expanded and weakly trilobed with a pair of subterminal 

 processes projecting within tube (fig. 251). The labium expanded at 

 tip and fringed as in figure 25 1 . The mandible attached to head near 

 base of tube (see fig. 250) and bearing a long process with extends be- 

 tween labrum and labium. Distal end of mandibular process with an 

 inner row of about 11 teeth (fig. 252). First maxilla (fig. 253) indis- 

 tinctly divided into 2 segments. Proximal segment with a group of 3 

 setae near base. Distal segment short and terminating as a blunt 

 process. Second maxilla (fig. 254) 3-segmented. Second segment 

 bearing a group of stout setules and a single seta at inner distal corner. 

 Third segment short, with 2 transverse rows of setules and bearing 

 a claw ornamented on proximal two-thirds of concave margin with 

 transverse rows of spinules and on convex surface with longitudinal 

 rows of spines. Maxilliped (fig. 255) apparently 4-segmented. First 

 segment bearing padlike process on anteroventral surface, which 

 undoubtedly serves as an adhesion pad. Third segment bearing a 

 heavOy sclerotized spinelike process opposed by claw of fourth seg- 

 ment, thus forming a chela. Fourth segment bearing a single seta 

 near base of claw. 



Legs 1-4 biramose, with spine and setal formula as follows : 



Leg 1 (fig. 256) with both rami 2-segmented. First exopod segment 

 outwardly greatly inflated and bearing a single outer spine. Last 

 exopod segment with 3 outer spines and 4 inner setae. First endopod 

 segment with no setae but second segment bearing 3 setae. Basipodite 

 bearing a short outer seta; inner margin naked except for a short seta. 

 No setae on coxopodite. Leg 2 (fig. 257) with both rami 3-segmented. 

 First exopod segment with an outer spine and an inner seta. Second 

 segment same. Third segment with 3 outer spines and 5 terminal 

 setae. First endopod segment with an inner seta. Second segment
