Dorsal Br-claw from about the 50"' segment l\ 10; 7 mm. Pg i;j; 7,5 

 mm. The L of distal pinnulars-=2 — 2^2 br. 



Sj). 32 (St. 53) R— s h = i/3 br with a dorsal crista. Dorsal 

 Br-claw from the 50"' segment. The L of distal pinnulars 2 br. 



■S';). 38 (St. 53j K— s as in the preceding specimen. Dorsal l^r- 

 spine from the 50"' segment. P. 14: 7 mm. — The L of distal pinnu- 



lars 2— Z 



br. P., of an arm grown out to a complele new arm. 



.S>. 84 (St. 5;^) CM i-aihcr low. Cirri typical. li— s h - ' a br 

 with a dorsal crista. A very indistinct carination of I Br 1 and 2 and 

 Br 1 and 2. Dorsal Br-spine from the 50"' segment, rather low but 

 rapidly increasing ihe last cm. The L of the distal pinnulars 2V'2br. 



.S>. 85 (St. 5;{) II of (\\ 2..-. mm., pointedly conical. K— s h = 

 V3 br with a doi'sal crista. Dorsal Br-spine from the 50"' segment. 

 The arms with SO— 90 Br— s. The L of distal pinnulars 2 br. — Para- 

 sitic StijUnas. 



Sjj. 80 (St. 53) Cd as before. Dorsal Br-spine from about the 

 40"' segment. The Br-segments 70—75. 



Adolescent or juvenile specimens. 



Sj). 37 (St. 53) Cirri: 1''' segment short, 2'' somewhat longer than 

 broad, 3^ L =^ 2i/2 br, 4"' and 5"' cirral L = 2 br, 0"' segment L = 1 1;2 br. 

 distally widened, 7"' and the following ones L = br, with an inconspi- 

 cuous dorsal carination. which is transformed distally into a dorsal 

 spine. Opposing spine h = V2 of the br of the segment. Terminal 

 claw about as long as the penultimate segment. 



B — s especially projecting in the corners, form basally a narrow, 

 continuous ring. K — s h = 1 ' 2 br, with a strong, longitudinal crista in 

 the pro.\imal 'a. R — s laterally contiguous, enclose practically the 

 whole intestinal sac. I Br — s I with a medio-dorsal crista, like the 

 axillaries well separated from each other laterally. The entire arm 

 otily 13 — 18 segments. 



Pi— P3 usually absent. Sometimes, however, Pj and P^ deve- 

 loped. Observe the considerable length of the distal pinnules, when 

 compared with the arm. The Br— s, especially Br S and 11, appear 

 almost as axillaries because of the relatively great size of the pinnules.
