longer than the breadth at the apex, and distinctly longer limn the inner ramus; the outer 

 ramus is longer but narrower than the inner, serrated along the inner margin, and smooth 

 on the onicr; the inner nunns is broadly lanceolate, narrow and sharp-pointed at the apex, 

 and serrated along both margins; it is a little longer than the breadth of the peduncle, 

 The telfion is broader than long, spade-shaped; ii is broader than, and more than 

 hull as long hs the peduncle of the last pair of uropoda; it equals in length the last ural 

 segment.

Hyperia Latreillei, II. Milne Edwards. 

 Dniwn from the supposed type specimen in the collection of the »Mus4e d'Histoire Naturellou in Paris. 



The body, especially the perscon, is much broader and wider than in the nude. 

 The pleon and urus together are a little shorter than the perseon. 



The head is as long as the first two perseonal segments together, and as deep as 

 broad; the depth equals the length of the lirsi four perteonal segments together. 



The first /nflf of antennce (1*1. X, fig. L4and IM do not reach to the under margin of 

 the head. The first joint of the peduncle is thick and stout, cylindrical, and longer than 

 broad; it is twice as long as the two following joints together, which are nearly equal 

 in length. The single flagellar joint is more slender than the peduncle, and much longer, 

 slightly curved downwards, and set with hairs along the under margin. 



The second pair of antennas (PI. X, fig. 1<> and 17) are nearly as long as the first 



pair. The three peduncular joints are almost equal in length, the lirsi being much the 

 thickest. The single flagellar joint is slender, evenly tapering towards the apex; it is 

 about as long as the whole peduncle, and is fringed along the margins with minute 

 hairs (PI. ,\, fig. 17). 



The mouth- organs are like those in the male. 



The epimerals arc somewhat deeper than in the nude.
