Head wider than long, 7 mm. : 4 mm., wider anteriorly than poste- 

 riorly, with the eyes, which are large, composite and kidney shaped, 

 situated in the posterior half, at the post-lateral angles. Front of 

 head roundly produced. In a dorsal view both pairs of antennae are 

 entirely concealed. The first pair have the basal article large and 



dilated; the second article is about half as 

 large as the first ; the third is slender and 

 elongate; the flagellum is composed of 

 about 11 articles and extends to the posterior 

 margin of the first thoracic segment. The 

 second antenna?, with a flagellum of 11 ar- 

 ticles, extend to the posterior margin of the 

 third thoracic segment. 



The first segment of the thorax has the 

 antero-lateral angles produced so as to sur- 

 round the posterior half of the head. All 

 the segments are about equal in length. The 

 epimera are not distinctly separated from 

 the segments ; they are produced posteriorly 

 in a quadrilateral process, with rounded 

 angles. 



The abdomen consists of two segments, 

 the first of which has three suture lines, in- 

 dicating partly coalesced segments. The second, or terminal, seg- 

 ment is about twice as broad as long, 5^ mm. : 11 mm. The posterior 

 extremity is roundly truncate. A carina crosses the basal portion 

 of the segment on either side. The inner branch of the uropoda 

 is fixed, immovable, and does not extend beyond the posterior margin 

 of the terminal abdominal segment. 

 The outer, movable branch is much 

 narrower than the inner branch, is a 

 little longer, and is produced to a 

 pointed extremity. Iri the female the 

 outer branch is equal in length to the 

 inner branch. 



The first two pairs of legs in the male 

 are subchelate. In the first pair the 

 propodus is large and oval in shape, 

 and is armed on the inferior margin 

 with stiff bristles and hairs. In the second pair of legs the propodus 

 is long and narrow, and has a rudimentary pollex at the base. The 

 following five pairs of legs are ambulatory and increase gradually 

 in length. In the female only the first pair of legs are subchelate 

 and are similar to those of the male,
