Victonan Decapod Crusfacea. 13 



the two joints together being subglobose. From the point of 

 insertion of the fifth joint there runs across their inner faces to 

 the articulation with the second joint a finely serrate ridge. All 

 the joints from the third upwards are sparingly fringed with 

 hair. 



Of the chelipeds either the right or left may be the larger. 

 The larger cheliped has a few small serrations on the lower 

 margin of the third joint, but the upper is unarmed. The fourth 

 has a well-delined ridge running longitudinally down its outer 

 face. On its lower margin there is a long anterior crest, and 

 near its distal end a well-detined tooth-like lobe. Both are 

 evenly serrate on the edge. The fifth joint is only three-quarters 

 as long as broad, and is clothed with a few scattered tufts of 

 hairs along its lower margin. The sixth joint is of the same 

 width as the fifth — the palm is subquadrate and the surface is 

 deeply pitted in its lower half. The tliumb is unarmed but 

 carries several scattered tufts of stiff hairs. The seventh joint, 

 which also bears scattered tufts of hair, slightly overlaps the 

 thumb at its distal extremity. It carries a faintly indicated 

 tooth in its distal half, and a strongly doubly crowned molar-like 

 tooth near the point of articulation. 



The smaller cheliped has the hand and palm of the same 

 breadth and approximately the same lengtli. The fingers are 

 separated by a wide interval, and the dactylus carries a small 

 tooth in its distal third. 



All the pereiopods are much flattened and leaf-like. The last 

 four pairs have the shape characteristic of the family, and all are 

 sparingly clothed with hairs. The fifth pair are subchelate. 



The telson is of the same length as the last segment of the 

 abdomen. It is unarmed, and has its posterior margin rounded 

 and sparingly clothed with short hairs on its margin. 



Both of the uropods are longer than the teLson. They are 

 rounded at their distal ends and carry a strong fringe of hairs on 

 their outer margin. 



The length of the type from the tip of the rostrum to the end 

 of the telson is 53 mm. 



These specimens appear to us to vary sufliciently from any of 

 those mentioned by Stebbing in his recent enumeration of the
