Hyperoche Martinezii. 



thirty-six long, spine-like teeth, the points of the teeth are directed downwards. The 

 metacarpus is almost as long as the stem of the carpus, broadest a little below the 

 base, somewhat tapering towards the apex; it is more than twice as long as broad, the 

 front margin is feebly curved, smooth, as long as the front margin of the carpus; the hind 

 margin is convex, strongly serrated, the teeth are long, spine-like, sharp-pointed, the points 

 directed downwards, they are more than thirty in number; the hind margin is consider- 

 ably longer than the front margin of the carpal process; the under margin of the meta- 

 carpus is armed with smaller teeth. The dactylus is nearly straight, smooth, not fully 

 half as long, as the metacarpus. Glands are developed especially in the femur, genu, 

 tibia, and carpus. 



The second pair (PI. VII, tig. 29) are a little longer than the first pair. The front 

 margin of the femur is convex, with a narrow groove for the reception of the following 

 joints; the hind margin is straight. The genu is as long as broad, smooth. The tibia 

 is longer than the genu, the lower hind corner is not at all produced, smooth. The 

 carpus is much shorter than the carpus of the first pair, the front and hind margins 

 are straight; the carpal process is narrow, slender, considerably longer than the rest of 

 the joint, the hind margin is convex, smooth, the front margin is nearly straight, as long 

 as the hind margin of the metacarpus, and armed with about forty long, sharp-pointed, 

 spine-like teeth, directed downwards. The metacarpus is much longer than the stem 

 of the carpus, broad at the base, rapidly tapering towards the apex, more than twice as 

 long as broad; the front margin is straight, much longer than the front margin of the 

 carpus; the hind margin is thin, edge-shaped, armed with about forty long, sharp-pointed, 

 spine-like teeth, directed downwards; the under margin is armed with smaller teeth as in 

 the first pair. The dactylus is straight, sharp-pointed, smooth, equalling in length a 

 little more than a third of the metacarpus. Glands as in the first pair. 



The third and, fourth pairs (PI. VII, fig. 30) are equal in length. The front margin 

 of the femur is curved, provided Avith the usual narrow groove, the hind margin is 

 straight, the lower corner is produced into a sharp point, tipped with a bristle. The genu 

 is somewhat more long than broad. The tibia is longer than the genu, smooth. The 

 carpus is only a little longer than the tibia, dilated, scarcely twice as long as broad! 

 the front margin is strongly convex, smooth, the hind margin is straight, divided into 

 two parallel edges, as described above in Hyperoche Luetkeni p. 101, the outer of the carpal 

 edges is produced into a strong, sharp-pointed process, directed downwards, the inner 

 edge is produced into a much shorter such process, both edges are fringed with very 

 long, sharp-pointed, bristle-like teeth. The metacarpus is longer and much narrower 

 than the carpus, the hind margin is armed with long, bristle-like teeth. The dactylus 

 is feebly curved, scarcely equalling a third of the length of the metacarpus. Glands in 

 all the joints. 



The fifth, sixth and seventh pairs are equal in length, and scarcely longer than the two 

 next preceding pairs. The femur is narrow, linear, nearly as long as the three following 

 joints together. The genu is somewhat more long than broad, smooth. The tibia is 

 longer than the genu, the hind margin is strongly convex, the front margin straight, 

 smooth. The carpus is longer than the tibia, the margins are smooth. The meta-
