Peraeopods 1 and 2, 2nd joint moderately stout, 6th longer than 5th, dactyl about 

 half length of 6th. Peraeopods 3 and 4, 2nd joint oblong, stouter in peraeopod 4 than

None of the gnathopods or peraeopods are armed with more than a few isolated 

 spinules. 



Pleopods with moderately long peduncles. 



Uropod 1 extending back about as far as uropods 2 and 3, outer ramus shorter than 

 inner which is slightly shorter than peduncle, both rami terminating in a short stout 

 spine, but otherwise unarmed. Uropod 2 similar to uropod 1. Uropod 3 uniramous,
