those of the first pair, but differing in a number of rather small 

 features. The basal joint is much broader but not longer than 

 that of the first leg, not produced. The second joint as long as 

 that of the preceding pair, but it increases almost gradually in 

 breadth from the base to the end, and the posterior margin is 

 slightly convex. The fifth joint, the hand, is somewhat shorter 

 but not more slender than that of the first pair, two and a half 

 times longer than broad, with the anterior margin considerably 

 less convex than tbat of the first pair, and the basal third is 

 much, broader than the distal third. The apparent posterior 

 (lower) margin of the hand is constituted of the real posterior 

 margin and the palm ; these two parts are marked off from each, 

 other by a small triangular process (fig. 12, ^.), and the palm is 

 two and a half times longer than the margin mentioned. The 

 palm presents the same two proximal spines as that of the first 

 pair, but these spines are somewhat longer and considerably 

 thicker; the major portion of the palm sbows a number of 

 minute saw-teeth and differs as a whole slightly from that of the 

 first leg. Thie sixth and seventh j oints (fig. 12) are a little thicker 

 than the corresponding joints of the first leg ; otherwise these 

 joints and the claw do not present any deviating feature. 



Third and fourth Fairs of Thoracic Legs (fig. 13). — These are 

 equal in size and shape, each about as long as the sum of the 

 third and fourth thoracic segments (fig. 1), and very slender. 

 The first joint is small, transverse, about as broad as the second 

 joint, which is two and a half times longer than broad. The 

 fourth joint is somewhat shorter than, but as broad as the fifth, 

 which is scarcely as long as but somewhat broader than the 

 sixth. The seventh joint is oblong, not half as long as the sixth ; 

 the claw (fig. 14, c.) is well marked off, somewhat longer than the 

 seventh joint (vii.), slightly curved, slender, decreasing a little 

 in breadth from the base to a small spiniform tooth originating 

 at the beginning of the very short, thin, and acute terminal 

 portion. A single subapical seta on the fourth and the fifth 

 joints, a couple of apical thin sets? on the sixth, and a very short 

 apical seta on the seventh joint. — No glands could be discovered 

 in these legs. 



Mfth and sixth Fairs of Thoracic Legs (fig. 15). — Eather 

 similar to the fourth pair, but a little shorter and differing in 

 several smaller points. The second joint is somewhat broader ; 

 the fifth joint is slightly longer than the fourth, with about four
