fish caught at Stuart, Fla.; USNM 102036 from sailfish caught at 

 Pass-a- Grille, Fla. 



Female. — Total length (mcludmg caudal rami) 10.90 mm (10.05- 

 11.70 mm) ; greatest width (measured at widest part of cephalon) 4.95 

 mm (4.50-5.25 mm) based on an average of 136 specimens. 



Body form as in figure 1. Dorsal sm-face of cephalon with rows of 

 hairs and spinules as indicated in the figm'e. Most hau's bifurcate. 

 Dorsal thoracic plate of segment bearing leg 4 wingiike, inner pos- 

 terior corner extending slightly over genital segment. Lateral edges 

 of plates held nearly parallel to body axis. Genital segment (fig. 2) 

 about as long as wide, narrowest anteriorly with posterior corners 

 projecting posteriorly. Lateral margin of genital segment with 

 slightly bulbous area bearing a row of spinules. Dorsal surface of 

 segment with prominent spines (usually 3) on either side of midpoint. 

 Abdomen (see fig. 2) 2-segmented ; 1st segment about one-half as long 

 as second segment; both segments with prominent spines on dorsal 

 surface as in the figure; 2 prominent spines on ventral surface near 

 posterior end of second segment. Abdomen comprises about 18.5 

 percent of total length. Caudal ramus (fig. 3) long and slender, 

 bearing a notch on outer edge of anterior quarter. Each ramus with 

 5 plumose setae (2 at notch and 3 terminal) and several prominent 

 spines (usually 8) on both sm'faces. 



Oral area with well-developed postantennal and postoral processes 

 (fig. 4). Postantennal process usually with 3 tines; innermost tine 

 occasionally bifm-cate producing a 4-pointed process (fig. 5). Post- 

 oral process with 2 tines directed posteriorly. Both processes heavily 

 pigmented. 



First antenna (fig. 6) 2-segmented; basal segment with a process 

 on anterior border and 23 stout plumose setae along anterior edge of 

 distal half; 2nd segment with distal half sclerotized bearing 1 sub- 

 terminal and 13 terminal naked setae. Second antenna (fig. 7) with 

 well-developed claw, heavily pigmented at tip. Mouth tube (fig. 8) 

 of usual caligoid type. Mandible a styliform process projecting within 

 tube bearing 12 teeth at tip. Fu'st maxilla reduced to a group of 2 

 setae anterior to postoral process (see fig. 4). Second maxilla (fig. 9) 

 long and slender, terminating in 2 weakly developed fringed spines. 

 Maxilliped (fig. 10) with a well-developed claw usually pigmented at 

 tip; adhesion area near distal end of basal segment. Sternal furca 

 (fig. 11) with innermost tine bifurcate and heavily pigmented. Lat- 

 eral to furca on each side is an accessory lobe, often bearing a process 

 on outer corner. 



Legs 1-3 biramose. Leg 1 (fig. 12) exopod 2-segmented. Last 

 segment with 3 terminal spines and 4 inner setae. Two innermost 

 spines bifurcate, each bearing a delicate median seta (fig. 13). En-
