hairs. The eggs are 0.125 mm. in diameter and 6 or more small bunches 

 on each oviger of the male. 



Ambulatory legs: Rather short, strong, with numerous spines on 

 appendages and especially on the coxal and tibial joints. On the 2 tibial 

 joints of each leg these compound spines are arranged in a double row 

 down the upper side of the joint. The 1st and 3rd coxal joints are equal 

 in length, the 2nd about half as long. The femur is as long as the com- 

 bined lengths of the 3 coxae. The tibial joints are each as long as the 

 femur, but slightly longer than the tarsus. The claw is over % the length 

 of the tarsus. There are no auxiliary claws. Length of the proboscis is 

 1.42; body, 1.2; abdomen, 1.1 ; leg, 6.35; lateral processes, 0.5. 



This species was described from a single specimen obtained from 

 Fucus in July, 1911, at Laguna Beach. 



Two other specimens were obtained by Hall in 1912, one from Fucus, 

 another from under a stone. 



I have collected a large number of these from Laguna Beach, but 

 almost always from under stones at low tide. I think their occurrence on 

 brown algae is somewhat accidental. Mostly they are under stones among 

 bryozoans, small sponges, or hydroids and are often covered with debris. 



Color: Light brown. 



Measurements of a Laguna Beach specimen are as follows : Body 

 length and breadth, 3.5. Proboscis, 1.3 long by 0.55 wide. Chelifori, 1 

 long. Palpi, 1st joint, 0.15 ; 2nd, 0.7 ; 3rd, 0.2 ; the rest, 0.8 long. Ovigers, 

 last joint, 0.1 ; next to last, 0.25 ; next, 0.2 ; next, 0.3 ; next, 0.65 by 0.16 ; 

 next, 1.05 by 0.1 ; next, 0.85 by 0.1 ; next near basal, 0.8 by 0.275. Ab- 

 dominal segment, 1.05 long by 0.2 at base, 0.15 farther along; the spines 

 are from 0.1 to 0.275 to 0.5 in length. The dorsal spines of the body are 

 0.425 long by 0.15 at base and 0.075 at tip. Spread of legs, 33.5. 



I have a large number of this species collected from Laguna Beach 

 during the last 25 years. They were never abundant, but were found 

 every season.
