 posterior end as at the anterior end, with the posterior margin widely 

 rounded, the anterior margin somewhat rounded and deflected down- 

 ward over the antennae. The eyes are indistinct and perhaps func-

of 1 mm. The second antennae are composed of ten articles and 

 extend almost to the middle of the first thoracic segment. The max- 

 illipeds have a palp of two articles. The palp of the mandibles is 

 composed of three articles. 



The head is but little immersed or set in the first thoracic segment. 

 The antero-lateral angles of the first segment extend one-third the 

 length of the head. The first and fifth segments are a little longer 

 than any of the others, each being 2 mm. long. The second, third, 

 fourth, and sixth segments are subequal, and each is 2 mm. in length. 

 The seventh segment is shortest, being only 1 mm. long. The epim- 

 era are narrow plates, distinctly separated on the last six segments 

 and extending the full length of the segment.
