beyond the epimera. The epimeni are distinct on all the segments with 

 the exception of the lirst. The first three are small and the first two 

 have the posterior margins rounded. The last four are acutely pro- 

 duced, the epimera extending to the 

 posterior margins of the segments, 

 but not to the extremity of the post- 

 lateral angles in the last three seg- 

 ments. 



All the segments of the abdomen 

 are distinct. The sixth or terminal 

 segment is rounded posteriorly. The 

 inner ])ranch of the uropoda is broad 

 with the extremity obliquely truncate; 

 it extends a little beyond the tip of 

 the terminal abdominal segment. The 

 outer branch is one-fourth longer than 

 the inner branch, is slightly narrower, 

 and is produced to a narrow rounded 

 extremity. 



All the legs are prehensile, with 

 long, curved dactyli. 

 There are two light longitudinal stripes or bands extending the 

 entire length of the body, one on either side of the median line.

Having seen Say's type specimen of Oymofhixi hinceohifn \f\\\ch. is in 

 the Academy of Natural Sciences of Philadelphia, I find that it should 

 be referred to the a'enus Nerocila.
