Side-plates deep, narrowing to a subacute apex, 6th somewhat blunter, 

 the sutures with segments fairly well marked, each with a ridge which 

 is a continuation of that on the segment, swelling out into a large 

 rounded tubercle at the junction with the segment and thence narrow- 

 ing to the apex. 



Pleon granular, except the first segment, which is smooth, bilobed 

 and partly concealed, suture of 2nd and 3rd segments not easily 

 distinguished among the granules, posterior margin of 4th finely 

 tuberculate, 2 submedian tubercles being more prominent than the 

 rest ; a large lateral round -topped tubercle and a smaller adjacent one 

 appear to belong to the 4th segment and not to the telson, but the 

 suture is difficult to trace. 



Telson of the normal Cymodocella type, but with 2 large submedian 

 apically acute projections ; whole surface of telson deeply pitted, each 

 projection with a large triangular pit on upper surface with several 

 granules in it. 



Antenna 1 inserted into a rounded pit on anterior margin of head, 

 1st and 2nd joints thickened and indurated, roughly quadrangular in 

 section, 2nd nearly half length of 1st, 3rd shorter than 2nd, more 

 slender and inserted at right angles to 2nd, flagellum a little more than 

 twice length of 3rd joint, 6-joiuted. 



Antenna 2 longer than 1st, peduncular joints increasing in length, 

 flagellum equal to peduncle, 9-jointed. 



Epistonie rather large, proximal end blunt, lateral margins gently 

 concave ; upper lip not projecting much from the arms of the epistome, 

 distal margin setose. 



Lower lip as in C. sublevis Brurd. (I.e. pi. 36s). 



Mandibles, cutting-edge obscurely bidentate, secondary cutting- 

 edge in left only, bideutate, spine-row with 1 spine in left, 3 in right, 

 molar strong, denticulate, palp slender with both 2nd and 3rd joints a 

 little longer than 1st. 



Maxilla 1 with 8 spines on outer plate and 3 plumose setae on inner. 



Maxilla 2 with 8 spine-setae on outer and middle plates ; inner plate 

 setose with 2 stout plumose setae on inner distal margin. 



Maxilliped with 4th-6th joints more produced internally than in the 

 figure of that of C. sublevis. 



Peraeopods similar to those of sublevis, but rather stouter, fur on 

 margins of 4th-6th joints thicker, armature of the joints similar ; 

 peraeopod 2 not greatly longer or more slender than 1. 



Male appendages on 7th peraeon segment contiguous at base, but 

 slightly separated distally, stout, apically subacute and excavate on 

 inner distal margin.
