DA.NAIA DUB1A.

The superior antennas are more than half the length of 
the body of the animal. The first joint of the peduncle 
is longer than the head ; the second joint is not much 
more than half the length of the first ; the third is lost 
in connection with the flagellum, which is longer than 
the peduncle, and fringed with fine cilia ; the inferior 
pair are not so long as the superior. The peduncle does 
not reach beyond the peduncle of the superior, and the 
flagellum is as long as the peduncle, and fringed with 
fine cilia. The first pair of limbs have the coxae hid by 
the coxae of the succeeding pair ; they are slender, and 
terminate in a long straight finger. The second pair of 
limbs have the first joint produced inferiorly and an- 
teriorly, so as to cover that of the first pair of limbs and 
the appendages of the mouth ; the inferior margin is 
serrated upon the posterior half. The wrist is short and 
inferiorly produced ; the hand is broader at the palm than 
near the wrist ; the palm is convex, slightly oblique, 
fringed with hairs, and imperfectly defined, the inferior 
angle being rounded. The third pair of limbs have the 
first joint produced rather deeper than the preceding ; 
it is irregularly serrated the whole length of the inferior 
margin ; the rest of the leg is long and slender, and 
furnished with many long hairs : the finger is long and 
powerful. The fourth pair of limbs have the first joint 
deeper than the preceding, not serrated along the in- 
ferior margin, but furnished with a row of solitary 
equidistant short hairs planted within the margin ; the 
posterior margin is excavated near the upper edge to 
receive the anterior lobe of the coxa of the succeeding 
pair of legs. The rest of the organ is similar to that of 
the first pair. The fifth pair have the first joint bilobed 
and the second joint ovately dilated. The two posterior 
pairs resemble the fifth. The caudal appendages are
