Ambulatory legs: Rather long, stout, no tibial process, few hairs 

 except on the tarsus. First coxal as long as wide, 2n(i twice as long, 3rd 

 1^2 times the length of the 1st. Femur about as long as the combined 

 length of the 2nd and 3rd coxals. Second tibial joint about the length of 

 the femur, 1st slightly shorter. Second tarsus less than half as long as the 

 2nd tibial joint. There is a double row of fine hairs along the sole and a 

 few longer ones on the end. No terminal claw, 2 auxiliaries well devel- 

 oped. 



Measurements: Body length, 1.3; proboscis, 1.05; abdomen, 0.36;

 were as follows: length, female type, 2.85; male, 2.5; maximum, female, 

 2.85, male, 1.38. Proboscis, female, 1.15; male, 0.9; maximum, male, 

 0.96. Body, female type, 1.35; male, 1.15. Caudal segment, female type, 

 0.3 ; male, 0.24. Transverse process, female type, 0.66; male, 0.75. Third

About 20 specimens were first reported by Hall from under stones, 

 at low tide, Laguna Beach, California, 1912, and over 50 specimens in 

 1912 from a similar locality. I have found this species every summer for 

 the last 25 years at Laguna Beach or near by. I have found it also at the 

 Isthmus at Catalina Island, under stones, and below Ensenada, Lower 

 California, perhaps several hundred in all. It is usually found under 

 stones at low tide among hydroids, bryozoans, and sponges. Also several 

 from the Hawaiian Islands. 



measurements of a Laguna Beach female specimen : Length of 

 body, 1.4 by 0.625, of which the lateral processes are on each side. Pro- 

 boscis, 1.2 long by 0.5 across the center, 0.25 across the tip, and 0.35 at 

 the base. Ocular elevation, 0.175 high by 0.028 across. Abdomen, 0.3 long 

 by 0.055 at the base, and 0.12 in the middle. Chelifori, 1st joint, 0.075; 

 2nd, 0.25; 3rd, 0.3; 4th, 0.2; 5th and 6th, 0.03; and last joint, 0.075.
