posteriorly dilated; the tibia is about as long as the carpus; the metacarpus is longer 

 than the carpus, armed with short, stiff spines along the anterior margin. 



The seventh pair reach scarcely to the extremity of the femur of the preceding pair, 

 having the femur posteriorly dilated and nearly as large as that of the preceding pair. 

 The other joints are almost rudimentary. 



The first pair of uropoda reach as far as the extremity of the ultimate pair. The 

 rami are as long as the peduncle, minutely serrated on both sides. The second pair are 

 shorter than the preceding, having the rami longer than the peduncle and serrated on 

 both sides. The ultimate pair having the peduncle reaching to the extremity of the rami 

 of the preceding pair, and having the rami scarcely one-fourth of the length of the peduncle, 

 short, lanceolate, smooth. 



The telson is small, cylindrical.

The head is feebly rostrate, longer than the first three pereional segments. The first pair 

 of antennae are evenly tapering toward the end, curved at the apex. The first and second 

 pereional segments are the shortest, the seventh is the longest. The first four pairs of 

 epimerals are a little deeper than the following. The carpus of the first pair of pjereiopoda 

 is broad, serrated, produced, longer than the metacarpus; the metacarpus is strongly ser-
