Cepbalotborax strongly arched dorsally. First segment about 

 equal in length to the following three. Superior antennae as long 

 as the cephalothorax, very stout, and of nearly equal thickness 

 throughout. Inferior angle of the body produced into a spine. 

 Fifth pair of feet, in the male, very large and strong. Caudal 

 segments of moderate length. Tail setae about half the length of 

 the abdomen. Length iVth of an inch. 



This fine species does not, strictly speaking, come within the 

 limits of a dredging report, seeing that we have found it only in 

 brackish water and never in the open sea. But as it has not 

 yet been noticed by any British author (except casually by myself 

 in the Report of the British Association for 1863) it seems desir- 

 able to describe it here as being nearly related to the other sub- 

 jects of this paper. The upper antennas are remarkably stout, 

 thickened at the base, and beset along the upper margin with 

 numerous short hairs. That of the male, on the right side (fig 2), 

 has two long terminal joints, at the base of which the "hinge" 

 is placed. The two joints above, and one below the hinge are 

 armed with serrated plates. The 11th, 12th, 13th, and 14th 

 joints have each usually a distinct but short spine ; the 15th and 

 1 9th are also armed in the same way, but their spines are much 

 longer. These are not shown with sufficient clearness in the 

 plate. The fifth feet in the female (fig. 9) are four-jointed, the 

 apical joint rounded, small, and having two stout setae, one large 

 and one small ; the penultimate joint has one or two setae, and is 

 produced at the inferior angle into a strong spine, which is some- 

 times serrated on the lower border. The second joint bears also 

 a slender bristle. The fifth feet of the male (fig. 10) are very 

 large and powerful, and are provided on their opposing edges 

 with several spines — mostly one in the middle of each joint. 

 The last abdominal and the caudal segments (fig. 11) are beset 

 with irregularly scattered short hairs or prickles. The caudal
