Specimens studied, — Eleven females and 1 male USNM 60465 

 from Hexanchus species from Monterey Bay, California. 



Female. — Body form as in figure 218. Total length 12.5 mm 

 (based on a single specimen). Greatest width 4.5 mm (measured 

 at widest part of cephalon). Carapace rounded about as long as 

 wide. Dorsal thoracic plates present on segment 4. Plates extend- 

 ing only slightly over anterior portion of genital segment. Genital 

 segment 5.8 mm long and 3.1 mm wide, about one-half body length. 

 Posterior corners produced dorsally and extending as rounded lobes 

 over abdomen and caudal rami. Abdomen (see fig. 219) 1-segmented 

 and with a large dorsal plate. Caudal rami large (2.6 by 1.3 mm), 

 joined to the abdomen distally (see fig. 219). Each ramus with 6 

 naked setae, innermost and outermost very short. 



Oral area (fig. 220) with adhesion pads associated with first and 

 second antenna and maxilliped. Adhesion pads small and not well 

 developed. A padlike process located between bases of maxillipeds 

 (fig. 221). This process is directed posteriorly and has a pad at tip. 

 Pad is divided by a median Hne suggesting a fusion of 2 pads. First 

 antenna (fig. 222) 2-segmented. First segment with 28 spines and 

 setae armed as in figure. Last segment with 9 naked setae. Second 

 antenna (fig. 223) small. Terminal claw not well developed. Ad- 

 hesion area near base. Mouth tube of the usual form. Mandible 

 with 12 teeth at tip. First maxilla (fig. 224) composed of a lobe with 

 articulated process at tip and basal process bearing 3 short spines. 

 Second maxilla of usual form. Terminal claw (fig. 225) subdivided. 

 Distal segment with rows of fringes as in figure. Subterminal segment 

 with patch of spines. Penultimate segment bearing prominent 

 spinose spine and group of long hairs. Maxilliped (fig. 226) with 

 terminal claw opposed by sclerotized protuberances on basal segment. 



Legs 1-4 (figs. 227-230) biramose. Spine and setal formula as 

 follows: 



Leg 5 (fig. 231) located on ventral surface of genital segment near 

 lateral margin (see fig. 219) and composed of single lobe with 2 naked 

 spines. Leg 6 (fig. 232) at area of spermatophore attachment and 

 modified to assist in this function.
