It is a matter of no little interest to find this genus occurring off 

 the coast of Japan, for it was previously known only from the West

viously known in its very short and thick arm spines, the lowest one 

 on the basal part of the arm being particularly characteristic. It is 

 interesting to find that in the relative width of the alternate bands 

 of granules on the arm the Japanese species does not resemble the 

 Australian form. Comparison of fig. 142 with that of A. aus- 

 tralianus a shows how distinct the two species are.
