area of back with, in the middle, an elongate-triangular patch of granules, which 

 narrows forwards to become the middle keel of the rostrum, where its granules pass 

 into a single row of about a dozen spines. At each side of this patch a strip of 

 granules, which just behind base of rostrum become spines. Outside this again the 

 edging -keel of the flat area, bearing from seven to ten spines, which are small behind, 

 but grow larger in front till the last is a stout thorn at some distance from base of 

 rostrum. Beyond this thorn, keel continued till it becomes side keel of rostrum, 

 where it bears six long spines. Eostrum thus bears above three spined keels. It 

 ends in an upcurved spine. Eyes well pigmented, reaching barely half-way along 

 rostrum. Antennular stalk outreaching rostrum by its end-joint. Second and third 

 joints subequal, and together shorter than first. Basicerite of antenna equal to first joint
