other extremity. This segment projects down over the last segment 

 at either side. The last segment bears a deep excavation at its poste- 

 rior extremity, around and above which is a 

 carinated ridge extending entirely around the 

 whole of the posterior half of the segment. 

 Two small longitudinal ridges are in the center 

 of the segment. The inner branch of the uro- 

 poda is very short, not reaching the extremity 

 of the abdomen 1)}" some distance; it is quad-

and obliquely truncated at the end. The outer 

 branch of the uropoda is long, curved, and pointed at the end, resem- 

 bling a hook somewhat. 



The color is a light yellow. In appearance the little isopod is very 

 rough and rugged looking. 



There is but one specimen, which was found off the coast of Georgia.

95. CILICiEA LINGUICAUDA, new species. 



Head subtriangular in shape; frontal margin with a small median 

 point; eyes post-laterally situated. The first pair of antenn;e reach the 

 posterior margin of the first thoracic segment; the second pair touch 

 the fourth segment. 



The first segment of the thorax is a little longer than any of the 

 others, which are similar in size. The epimera are distinct from the 

 segments, and are produced into acute points, with the exception of 

 the last, which has the epimera quite rounded. 



The abdomen is composed of two segments, the first of which gives 

 indication of three coalesced segments, and has a small tooth on each 

 side on its post-lateral margin. The last segment is swollen ante- 

 riorly, and bears three low tubercles on this portion. The extremity
