 5ti,_9th slightly longer, then shorter segments again, 10"' — 12*'' segments 

 with a dorsal transverse ridge, 13"' — 10"' with a 3— pointed prominence. 

 16"' — 24* with a double spine then a single dorsal spine. The 

 double pi'ominenees sometimes not distinctly sepai'ated. Dorsal spine 

 verv small, but in side view well bounded, fixed at the middle of the 

 cirral. h = ^ .t of the br of the segment. Opposing spine considerably 

 larger h = V/2 — ^/a of the br of the segment. Terminal claw pointed, 

 curved, about as long as the preceding segment. 



R— s projecting under the margin of Cd. I Br 1 h = \'6 br, late- 

 rally free. 1 Brax h = V'2 br, the lateral sides bent at a slight angle 

 to the preceding ossicle. A well-developed synarthrial tubercle be- 

 tween 1 Br 1 and 2. II and III Br— s : 2, the later ones on the outer 

 sides. Arms XXVI, broken (probably XXVIII in a complete specimen).
