TERRA NOVA " EXPEDITION. 



be a little shorter, than the antenna] scale. The relative lengths of the last two joints 

 of the third maxilliped and also those of the wrist and hand of the first leg vary a 

 little. The wrist does not exceed the hand in length. The telson is seldom perfect, but 

 in undamaged specimens it may be seen to bear at the end two pairs of spines — a small 

 lateral and a long intermediate pair — and between the intermediate spines five bristles. 



I can detect no constant difi'erence between the " Terra Nova " specimens and 

 South Georgian examples. 



Numerous specimens were taken at Stations 294, 314, 316, 318, 338, 339, 340, 

 348, 355, 356.

Diagnosis. — Body sparsely hairy all over. Rostrum as long as rest of carapace, 

 slightly upcurved, with a ridge along each side, but rounded above except at the tip.

where it is prismatic ; bearing below seven teeth, of which the first is subdivided into 

 three smaller teeth. Carapace with antennal and pterygostomian spines. Abdomen 

 strongly bent ; the third to fifth segments keeled and bearing a median spine behind, 

 the fifth also with two spines on each pleuron, the sixth long, with a lobe bearing a 

 spine projecting backwards on each side. Uropod slightly longer than telson, its 

 endopodite and exopodite subequal. Telson longer than sixth segment, diminishing 

 evenly to the end, which is truncate, with a median tooth. Antennular stalk about 

 one-third length of rostrum, its second and third joints subequal, together shorter than 

 first joint, which has a strong stylocerite projecting beyond it ; upper flagellum reaches 

 just beyond middle of rostrum, lower just outreaches antennal scale. Antennal stalk 

 nearly as long as antennular. Antennal scale four-fifths length of rostrum, its sides 

 converging towards a narrow truncate end, at one side of which stands the terminal 

 spine. Third maxilliped outreaching antennular stalk ; its end-joint sharply pointed,
