pair of antennae are composed of ten articles and extend beyond the 

 middle of the first thoracic segment. The maxillipeds have a palp of 

 two articles. The palp of the mandibles is composed of three articles. 

 The first and fourth segments of the thorax are subequal and each is 

 3 mm. in length; the second and third are subequal and each is 2 mm. 

 long; the fifth and sixth are each 4 mm. in length; the seventh is 2 

 mm. long. The epimera are distinctly separated on the 'last six seg- 

 ments. Those of the second and third segments extend the full length 

 of the lateral margin; those of the fourth and seventh segments extend 



one-half of the lateral 

 margin; those of the fifth 

 and sixth extend one- 

 third of the lateral mar- 

 gin. The first two are 

 rounded posteriorly; the 

 last four have the outer 

 post-lateral angles 

 acutely produced. 



The first segment of 

 the abdomen is as wide as 

 the seventh thoracic seg- 

 ment. The abdomen is 

 not set in the thorax and 

 all the segments are dis- 

 tinct. The second, third, 

 fourth, and fifth segments 

 become gradually some- 

 what narrower. The 

 sixth or terminal seg- 

 ment is not wider at the 

 base than the fifth seg- 

 ment; it is widely rounded 

 posteriorly, and is as long 

 as wide, 7 mm. :7 mm. 

 The uropoda are as long as the terminal abdominal segment, are of 

 equal length and width, and are rounded posteriorly. 



All the legs are prehensile with long, narrow, curved dact3 7 li, 

 those of the second and third pairs being much longer than the others. 

 The last pair of legs are longer than any of the others. There is a very 

 low carina on the basis of the last four pairs of legs/*
