 of the h, like Br 2 broader on the outside. The ossicles laterally 

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

 3 + 4, 21 +22. 32-3:1 42-43 etc. Avith an interval of S-10 oblique 

 articulations. In one abnormal case, however:

The specimens are closely related io A. macropoda, from which 

 they differ by having almost smooth |)roximal brachitils. 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. anIJms. The dorsal spines of the cirri 

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