produced, is truncated, and fringed with half a dozen stout bristles. The carpus is a little 

 shorter than the two preceding joints together, dilated, and a little longer than it is broad 

 at the lower end ; it is scarcely produced, but the margins of the under side of the joint 

 are densely fringed with long stout bristles; those surrounding the base of the metacarpus 

 are especially long, about half as long as the metacarpus itself; the front margin of the 

 carpus is feebly curved at the lower corner; the hind margin is almost straight, -with- 

 out notches. The metacarpus is as long as the carpus, very broad at the base, abruptly 

 narrowing towards the apex, and scarcely twice as long as broad at the base; the front 

 margin is strongly convex, indistinctly notched, and armed with three or four long 

 bristles; the hind margin is almost straight, showing five or six strong notches, and mi- 

 nutely serrated between the notches; each notch carries a stout spine-like bristle which 

 is feathered, that is to say provided with a minute serration consisting of very fine, spine- 

 like teeth along its lower half (PL X, fig. 35). The metacarpus carries a few bristles on 

 the sides, some longer and some shorter. The dactylus is curved, armed with six or 

 seven low, sharp, triangular teeth along the hind margin, and provided with a large ovate 

 hole at the base as usual. The dactylus is more than half as long as the metacarpus, 

 and considerably longer than the greatest breadth of the metacarpus. Large glands are 

 fully developed in the femur and also present in the four following joints. 



The second pair (PI. X, fig. 36) are almost shorter and less stout than the first 

 pair, and reach to the apex of the tibia of the third pair. The femur is as broad as in 

 the first pair and somewhat longer than the four following joints together; it is nearly 

 twice as long as broad; the front margin is strongly convex. The genu is as long as 

 broad. The tibia is longer than the genu; the lower hind corner is produced and fringed 

 with half a dozen long bristles. The carpus is strongly produced at the lower hind 

 corner and is with the process quite as long as the two preceding joints together; the front 

 and hind margins are slightly convex, without bristles; the lower margin is fringed with 

 long stout bristles round the base of the metacarpus; the carpal process is broad, trun- 

 cated at the apex and much shorter than the rest of the joint; its margins, especially at 

 the apex are fringed with long bristles. The metacarpus is more slender than in the 

 first pair, evenly tapering and much more than twice as long as it is broad at the base; 

 the front margin is convex, smooth; the hind margin is straight, notched, serrated, and 

 armed with stout spine-like bristles as in the first pair. The dactylus is nearly half as 

 long as the carpus, the hind margin is armed with low, sharp, and triangular teeth. The 

 glands are less developed than in the first pair. 



The third and fourth, pairs are more slender than in Hyperia medusarum. The 

 femur is elongate-ovate, more than twice as long as broad. The genu is somewhat 

 longer than broad, and smooth. The tibia is twice as long as the genu, without bristles, 

 but the hind margin is fringed with minute spines. The carpus is a little longer than 

 the tibia and armed in the same way. The metacarpus is long, slender and consider- 

 ably longer than the carpus, and fully half as long as the femur; the hind margin is 

 fringed with minute spines. The dactylus is feebly curved, and about a fourth part 

 as long as the metacarpus. Glands are present in all the joints except in the dactylus.
