The external maxillipeds have the distal margin oblique with a 

 small triangular projection above the base of the palp. 



It is of interest to note that the younger specimens appear to be 

 much more granulose than do the older ones ; this is due largely to the 

 fact that the coarse granules appear larger in proportion to the small 

 carapace and especially to the small joints of the legs.
