The fourtli pair [Pl. II. fig. 14] are scarcely a sixth 

 longer than the third pair. The femur is long, narrow and 

 linear, with a few simple and ciliated hairs at the outer mar- 

 o;in. There is no excavation at the lower outer corner, but 

 the corner itself is flattened into a narrow lamina. The gemt 

 is only a third of the length of the femur, and armed with 

 a row af strono- bristles round the lower maro-in, The tihia 

 is a little longer than the genu, nearly linear; it carries brist- 

 les along the inner side and round the lower margin. The 

 carpus is shorter than the tibia, of the same form, and armed 

 in the same way, but the bristles along the inner side are 

 much smaller. The metacarpus is narrower, very little lon- 

 ger than the preceding joint, and provided with only two 

 bristles at the lower margin and none at the side. The end 

 of the joint forms a process for the articulation of the dacty- 

 lus, as in the preceding pairs, but not so strong and well 

 developed. The dactyliis is indistinctly pedunculated. The 

 excavation at the inner side is not very distinct. The dac- 

 tylus is shorter than the metacarpus and feebly curved; the 

 indistinct peduncle is more than two times longer than the 

 claw itsef. 



The fiftli pair [Pl. II. fig. 15] are nearly a third longer 

 than the fourth pair. The femur is long and broad, the inner 

 margin is curved and smooth, with the exeption of two small 

 bristles at the lower corner; the outer margin is straight, 

 flattened into a lamina carrying some long simple hairs, and 

 ending at the lower corner in a sharp rounded edge. When 

 the leg is folded up, the genu, tibia and carpus are placed 

 along this lamina. The genu is about a fourth of the length 

 of the femur, with two bristles at the inner, and two at the 

 outer lower corner. The bristles are stout, each carrying a 

 hair [Pl. II. fig. 16]. The tihia is longer than the genu and 

 carries some bristles at the lower corners. The carpus is a 

 little shorter than the preceding joint, with two short brist- 

 les at the inner side, and some longer ones round the lower 

 margin. The metacarp\is is shorter than the carpus but 

 longer than the dactylus. It carries three bristles along the 

 inner side and one at the corner. At the lower outer corner 

 there are three strong bristles and a long ciliated hair [Pl. II* 

 fig. 17]. The lower end is produced into a process of arti- 

 culation like that in the preceding pair, but stronger. The
