Dorsal Bi-elaw fi-om about the 50"' segment l\, 10; 7 iiiiii. 1',, i:')-. 7,5 

 nini. The L of distal pinnulars = 2 — 2'/2 hr. 



Sp. 32 (St. 53) R— s h = 1/3 br with a dorsal crista. Dorsal 

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



Sp. 83 (St. 5;J) K— s as in the pi-eceding specimen. Dorsal I5r- 

 spine from the 50"' segmi'iit. P,- 14; 7 nun. The L of (lislal |)iiinii- 

 lars 2 — 21/2 br. P., of an arm grown out tu a complete new arm. 



Sp. 34. (St. 53) Cd i-ather low. Cirri typical. R — s li = '/2 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, rathei' low l)ut 

 rapidly increasing the last cm. The L of the distal pinnulars 2' j bi-. 



.S)). 35 (St. 53) H of Cd 2,5 mm., pointedly conical. M — s h 

 1/3 br with a dorsal crista. Dorsal Br-spine from the 50"' segment. 

 The arms with 80—90 Br— s. The L of distal pinnulars 2 br, — Para- 

 sitic Siylinas. 



Sp. 36 (St. 53) Cd as before. Dorsal Br-spine from about the 

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



Adolescent or juvenile specimens. 



Sp. 37 (St, 53) Cirri: I''' segment short, 2'" somewhat longer than 

 broad, 3*1 L = 2i/2 br, 4* and 5"' cirral L = 2 br, 0'^ segment L= I1/2 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 -= 1 2 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. R — s h=li/2br, with a strong, longitudinal crista in 

 the proximal -3. R — s laterally contiguous, enclose practically the 

 whole intestinal sac. I Br — s 1 with a medio-dorsal crista, like the 

 axillaries well separated from each other laterally. The entire arm 

 only 13 — 18 segments. 



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

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

 compared with the arm. The Br — s, especially Br 8 and 11, appear 

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