•' The 13-spineJ allies of Sebastodes constitute a most striking feature of the fauna of the north Pacific, 

 the species hein^ very numerous on the rocky coast of California, Alaska, and Japan; a few also in Chile. 

 The species are in general well defined, showing little individual variation and no sex changes. It is ex- 

 tremely difQcult, however, to divide them into genera, the various traits being intertangled to a remark- 

 able degree. Yet such species as paucispinis, rosaceiis, and nigrocinctus could hardly stand in one genus 

 in a natural system. It may be noted that the group called Sebastodes is the simplest in organization and 

 also the oldest, four well-marked species related to Sebastodes paucispinis occurring in the upper Miocene 

 of California.
