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

 the exception of the first. 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 branch 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.

Having seen Say's type specimen of Cymothoa lanceolata which is in 

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

 be referred to the genus Nerocila.
