CYCLOPOIDEA. hqj 



The pigment of the inferior eyes is seen in a vertical view just 

 behind the superior eyes, and is transverse, being slightly oval. The 

 antennae have the setae towards the base numerous, and but little 

 longer than two diameters of the joints. The male right antenna is 

 bent outward a little at the large joint, and again forward at the third 

 articulation from the extremity. The character and colour presented 

 in figure la, were constant for the larger specimens. But some 

 smaller individuals had the cephalothorax obtuse behind, with a very 

 short posterior segment (as in fig. 1 c), and the abdomen was only two- 

 jointed. The length of the caudal stylets is more than twice their 

 breadth. 



The beak in many individuals was large ventricose at base, as 

 shown in figure la'. 



The right posterior leg of male is very large. The second joint is 

 stout oblong. The next is very broad, sub trapezoidal, with the upper 

 side arcuate, and the two others nearly straight, the one opposite the 

 articulation with the second joint dentate, the other bearing two 

 remote setae ; the base of this joint is prolonged outward into a long, 

 curving spine, into which the joint diminishes. The fourth joint is a 

 long arcuate finger articulated with the more distant angle of the 

 dentate side of the third joint. The left leg of the same pair is 

 simple, and terminates in a short joint, bearing four bent unequal 

 spines. 



The males and females contain within a deep blue glandular mass, 

 which extends along either side, somewhat irregularly, nearly to the 

 base of the posterior antennae, and two spots of similar colour appear 

 through the silvery back, one behind the other. 



Var. formosa. (Plate 82, fig. 2 a, a'.) — The individual here figured 

 closely resembles the preceding, and was collected at the same time. 

 The anterior and posterior antennae, the eyes, and the caudal stylets, 

 are similar to the above; so also the general form of the body, except 

 that there were four posterior segments to the cephalothorax, the last 

 very short, and the posterior angles were less prominent ; also, the 

 abdomen was three-jointed. The anterior antennae were a little 

 shorter than the cephalothorax ; the second joint shorter than in the 

 preceding, owing apparently to articulations across its apical portion, 

 which thus make twenty-three or twenty-four joints to the antenna. 

 The colour strikingly differs, the body being clear yellow, verging to
