First and second peraeopods, 2nd joint equal to 3rd and 4th 
together, 5th shorter than 4th, 6th subequal to 4th, finger more 
than half length of 6th, with secondary margins at apex, posterior 
margin 4th, 5th and 6th joints with long setae, none of the joints

Fourth peraeopod, 2nd joint oblong, half as long again as broad, 
anterior margin distally with 12 spines, posterior margin straight, with
