lary h = '/2 br. Arms X, 65 mm. Br— s 1 inside iiniied in paii's to Va 

 of the il, lil<c Br 2 broader on tlie outside. Tlie ossicles laierally 

 flattened out to Br 4. After Br 10 oblique joints. Syzygies usually 

 3 + 4, 21 + 22, 32 + 33. 42 r 43 etc. with an interval of S- 10 oblique 

 articulations. In one abnormal case, however: 



I 1-2 



Br 1—2 3 ^ 4 (5 f 0) . . . 22 + 23 . . . 3S + 39 . . 

 Br 1-2 27 + 28.... 



After Br 50( — 00) a prominent^ distally directed, median, dorsal claw 

 which on the outermost segments becomes a strong spine, h = '/3 — V2 

 of the br of the Br, when viewed in lateral profile. 7 — 8 of the most 

 distal Br — s with rudimentary pinnules. 



I\ 9 — 10; +5 mm^ (P^ 10; 5 nun., a little more slender) coarse 

 and thick with prismatic pinnulars. P' and 2"^ segments short, the 

 other ones somewhat longer than broad. P, 8 — 10; 5 mm., P3 similar, 

 Distal p. 16; 6,5 mm. Disk thrown off. Colour (in spirit] white. 



aS/>. 2 (St. 12) C. XV 85—90: 75—80 mm. A dorsal spine from 

 about the 40"' segment. 



I Br 1 — 2 with a slight synarthrial prominence. Each of the 

 two ossicles with a central, inconspicuous, small wart. I Br 2 more- 

 over with 2 low ridges starting from the wart and running proximo- 

 laterally. Arms X, 70 mm. Ex. of syzygies: 3 + 4, 9 + 10, 13 + 14. 

 19 + 20... or 3 + 4, (7 + 8), 14+15, 19 + 20, 26 + 27,32 + 33,44 

 + 45, ... A dorsal Br spine from about the 50"' segment. The rudi- 

 mentary Br — s are 8. 



Pi 13; 5,5 mm., P2 10: 5,7 mm.. P., 11: P^ 12; 6 mm., P, 14: P,, 11, 

 of about the same length. Distal p. 16—20; 7 mm. (P' and 2'' seg- 

 ment shorter and a little thicker than the following ones, the L of 

 which is 1 V2 X br). The pinnules laterally compressed and therefore 

 with a dorsal I'im. — Disk thrown off. 



The specimens are closely related to A. inacropoda, from which 

 they differ by having almost smooth proximal brachials. Sp. 1 is a 

 rather young individual with cirri shorter than the arms. The radial, 

 dorsal tubercles of Cd are, however, well developed and by this it can 

 easily be distinguished from A. anthus. The dorsal spines of the cirri 

 are not so prominent and pointed as in A. anilrufi (cf. the figures).
