TEMORA. 57 



the male has two long apical joints, at the base of 

 which the hinge is placed, the two joints above and 

 one below being armed with serrated plates ; the llth, 

 12th, 13th, and 14th joints have each usually a dis- 

 tinct but short spine, the 15th and 19th bear also 

 similar but larger spines, and the number of joints is 

 reduced to twenty-one owing to the coalescence of 

 some of the number ; the middle of the male antenna, 

 as in the previous species, is much swollen. Fifth 

 pair of feet in the female (fig. 3) 4-jointed, the ter- 

 minal joint very small, rounded, and bearing two 

 stout setaa, one large and one small, the other joints 

 very much stouter, the penultimate produced below at 

 the inner angle into a long serrated spine; the 2nd 

 and 3rd joints bear each a single small seta. Fifth 

 feet of the male very large and powerful, and pro- 

 vided on their opposing edges with several spines 

 mostly one in the middle of each joint ; each branch is 

 3- jointed, the basal joints large and swollen, the ter- 

 minal joint of one side ending in a blunt doubly 

 toothed broad extremity, that of the other side form- 

 ing a long slender claw. The middle segment of the 

 abdomen in the female is much the shortest (fig. 5) ; 

 the last abdominal and the caudal segments are beset 

 with irregularly scattered short hairs or prickles. 

 Caudal segments four times as long as broad ; about 

 equal in length to the terminal setse, or to half the 

 length of the abdomen. The ova are borne in a large 

 undefined mass on the front of the female abdomen, 

 and large oblong spermatic tubes are often found 

 attached in the same situation in great numbers,
