margin is convex ; from the dorsal view it appears truncate, 

 c/. also bispinosiis p. 589. 



Colou7\ — Chevreux in his original description gives the colour 

 as yellowish with some brown spots ; in his later account he 

 describes it as generally uniform yellow, some specimens with 

 brown bands dorsally. In Grube's type the colour is still vivid, 

 tawny yellow, with round stellate markings in light and dark 

 reddish-brown. These markings occur on the head ; in transverse 

 bands on segments 2-10 ; on the sideplates ; and on the posterior 

 expansion of the basal joints of the hinder perseopods.
