Color in life cream and generally devoid of pigmentation. 

 Legs 1-4 bii'amose, with spine and setal formula as follows: 



Leg 1 (fig. 52) with both rami 2-segmented. First exopod segment 

 with outer spine. Last exopod segment with 6 spines, outer 3 naked, 

 inner 3 finely plumose. First endopod segment with adhesion pad. 

 Last endopod segment with 3 inner spines. Basipod having an 

 inner and outer spine with 1 adhesion pad. Leg 2 (fig. 53) with both 

 rami 2-segmented. First exopod segment with 1 outer spine and 

 patch of fine spinules on outer distal half. Last segment with 9 

 spines, outer 4 spinose and inner 5 naked. First endopod segment 

 unarmed. Second endopod segment with 5 short spines at tip. 

 Leg 3 (fig. 54) with both rami 2-segmented. First exopod segment 

 with spine on outer distal corner. Second segment with 6 short 

 spines. First endopod segment unarmed. Second segment with 2 

 short terminal spines. Leg 4 (fig. 55) with both rami 1-segmented. 

 Exopod segment with 6 spines. One spine placed at midpoint of 

 outer edge suggesting a 2-segmented ramus. Endopod unarmed. 

 Leg 5 (fig. 56) consisting of naked spine and separate plumose seta. 

 Leg 5 located near point of attachment of spermatophores (see fig. 56) . 

 Area of spermatophore attaclunent located at junction of abdomen 

 to genital segment and composed of a heavily sclerotized area with 

 shelf to receive neck of spermatophores, attaching in these areas 

 with necks crossing to opening of seminal receptacle on opposite side. 

 Egg strings long and of usual generic type. 



Color in life creamy yellow with light brown pigmentation as indi- 

 cated in figure 46. 



Male. — Body form as in figm'e 57. Total length based on 1 speci- 

 men, 9.5 mm, including caudal ramus but not setae. Greatest width 

 4.5 mm, measured at widest part of cephalon. Cephalon rounded, 

 slightly longer than wide (4.9 by 4.4 mm). 



First thoracic segment fused with head. Segments 2-4 free without 

 dorsal plates. Genital segment longer than wide, 2.2 by 1.7 mm with 

 spermatophore visible within. Abdomen of 2 segments. First 

 segment 360/i long. Second segment 612;li long. Caudal ramus 

 (fig. 58) bearing 6 setae, inner 4 long and plumose, inner margin of 

 caudal ramus bearing row of hairs. 



Oral area similar to that of female. In adult male adhesion pad 

 associated with second antenna only about one-half length of pad of 

 first antenna (264:576/x) (see fig. 59). Collected with this mature 

 male was also a young male (7.1 mm) with spermatophores developing
