Here follow the characteristics which are to be tbuiicl in the generic and specific 

 descriptions given by H. Milnk Edwards. 



The liead is very lai'ge, less elevated than the person, and ahnost entirely uccupied 

 by the eyes. 



The (first pair of) antennce are very short, subulate, much resembling the second 

 pair of antennse in the female of Hyperia. 



The perceon is not inflated in the niiddle as in Hyperia Latreillei, but gradually 

 diminishing in size backward. The first segment is ver}' narrow, and almost entirely con- 

 cealed by the second. 



The jir.^t tico pairs of perceopoda are very small, compressed, similar in shape. The 

 carpal process of the tirst pair is very small, that of the second pair is long, almost as 

 long as the metacarpus. The dactylus is curved. 



The third and fourth pairs are longer than the fifth and sixth. 



The peduncles of the jjleopoda are longer and more slender than in Hyperia; the 

 rami are almost linear. 



The urus resembles that in Hyperia, but the rami of the uropoda are elongate- 

 lanceolote, acute.
