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 setae are distinctly longer than the majority, and from 
this joint the setae 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 
setae 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 setae 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 setae 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 effect 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 
coxrn are nearly equal in length and all are minutely spinose. The Genital apertures 
occur on the second coxrn of all the limbs, and the lateral line beginning on that 
joint is conspicuous to the end of the lim]j. 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 setre, 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
