MARINE COPEPODA OF NEW ZEALAND. 37 



long falcate spine, the concave margin of which is distinctly pectinated ; the basal 

 joint of the fourth (?) pair of feet bears also a very long falcate spine (fig. 24). Male 

 unknown. 



This description is extremely imperfect, being based upon only two battered 

 specimens which were taken— one off Napier in the net at a depth of 8 fathoms, the 

 other at the surface in Otago Harbour. 



The characters seem clearly to distinguish this from any described species. 



Subfamily Pontbllinj). 



Genus Labidocera Lubbock. 



1. Labidocera cervi Kramer. (Plate X. figs. 8-14.) 

 Labidocera cervi Kramer (i), p. 218, pi. xvi. figs. 6, 7. 



Female. — Cephalothorax subtruncate posteriorly, the ventral angles produced and 

 mucronate (fig. 9). Abdomen four-jointed, the first, second, and third segments about 

 equal, fourth about half as long as the preceding ; caudal lamina? rather longer than 

 broad, obliquely quadrate (figs. 9, 13); terminal setae scarcely as long as the abdomen. 

 Antennules reaching to the posterior extremity of the cephalothorax. Fifrh pair of 

 feet (fig. 10) alike on both sides, two-branched, the internal branch composed of one 

 small joint, the outer of one much larger joint which bears three moderately large 

 lateral teeth and two smaller and much more slender ones at the apex. In the immature 

 condition, however (fig. 11), the outer branch consists first of three and afterwards of 

 two joints. Length 2 - 3 millim. 



Male. — The infero-posteal angles of the cephalothorax (fig. 13) are not quite so 

 strongly spined as in the female ; the abdomen five-jointed (fig. 13). The armature of 

 the right antennule consists of a fine pectination of the seventeenth and eighteenth 

 and of the coalescent nineteenth, twentieth, and twenty-first joints : the twenty-second 

 joint is prolonged internally, forming a sharp process which extends beyond the 

 apex of the penultimate joint. The right foot of the fifth pair (fig. 14) is strongly 

 prehensile, the basal joint simple, second joint attached near the middle by a hinge- 

 articulation, its outer portion forming a slender flexuous process, its inner portion 

 forming a broad lamina and giving attachment at its apex to a long and slender falcate 

 joint which opposes the outer process of the second joint ; the foot of the left side is 

 simple, slender, three-jointed, nearly as long as that of the right side, its terminal joint 

 having a few short apical teeth and near the distal extremity a diffuse pubescent patch. 

 Length 2 - 8 millim. 



Hab. In the surface-net, from Otago and Akaroa.
