surround the distal extremity of this joint and the next ; beyond this the setae are so 

 thickly distributed that it is scarcely possible to make out any definite arrangement. 

 On the fifth joint some of the setse are distinctly longer than the majority, and from 

 this joint the setse on the inner side of the appendage, in its natural position, are much 

 the longest. 



The Ovigers arise immediately behind the palps on a conspicuous body-process 

 close to the middle line (fig. 2a). The first three joints are small, and bear spinous 

 setse of small size. The fourth and sixth are very long and sub-equal, the fifth being 

 not more than a quarter of their length. The four terminal joints are sub-equal in 

 length, but decrease in stoutness. The entire appendage is setose. On the fourth 

 joint the setse are small and arranged in rows, and on the outer margin, at about 

 two-thirds of its length, a small but distinct, rounded protuberance occurs. On the 

 succeeding joints the setse or spines, whichever they may be called, are more thickly 

 distributed. The characteristic spines of the four terminal joints present very slight 

 differences from the two preceding species. On the ventral side of the limb in its 

 natural position are two rows of these spines separated by a conspicuous interval ; the 

 more ventral of these two rows consists of a few large spines, the other contains 

 approximately double the number of smaller spines. Dorsally, and separated by an 

 interval, are two rows of smaller spines, which are not, however, arranged with such 

 precision as the others. Close examination reveals the fact that the intervals between 

 the rows of spines are more apparent than real, this efi"ect being due to the set of the 

 first two rows and the third group or double row ; the second row is deflected at the 

 extremity by the articulation of the succeeding joint. The spines do not present 

 any special peculiarities, being more like true spines than in the other species here 

 described. They are somewhat curved or falciform (Plate X., fig. 3). The terminal 

 claw is of moderate dimensions, rather slender, but with a stout base ; in most of the 

 specimens the stout base is all that is left. All four terminal joints are dorsally 

 covered with short spinous setse set in sockets (Plate X., fig. 4). In this species they 

 are much more numerous than in the other three. 



Concerning the Legs, the first coxa has a slightly greater diameter than the others, 

 and bears the dorsal and ventral mark so characteristic of the genus. The other two 

 coxse are nearly equal ia length and all are miuutely spinose. The Genital apertures 

 occur on the second coxse of all the limbs, and the lateral line beginning on that 

 joint is conspicuous to the end of the limb. The first tibia is the longest joint of the 

 limb, the femur is very little shorter, the second tibia approximates to three-quarters 

 the length of the first, and the tarsus to very nearly half its length ; the propodus is 

 shorter than the tarsus by nearly a third, and the claw is less than half the length of 

 the propodus. The entire limb is covered with minute setse, which, along the dorsal 

 surface at any rate, have a distinct linear arrangement ; ventrally this becomes 

 indistinct from the second tibia onwards. The distal extremity of each joint, 

 including the coxse, is more or less completely girdled with spines, minute up to
