The following is the description given hy Filhol (/. c. p. 431) : — " The smooth carapace 

 hears on its anterior and median portion a very strong spine (rostrum), which reaches 

 lieyond the front of the eyes. This spine has on the anterior portion of the upper margin 

 two acute teeth directed forwards. Two much smaller spines are produced on the median 

 line immediately hehind the first one. These are reduced and are directed upwards and 

 forwards. Immediately outside of the frontal anterior spine are two other long spines 

 without teeth, which project as far as the space hctween the two little teeth on the 

 rosti'um. The ocular peduncle is completely hidden. The first antenme have the hasal 

 joint rather large, and they hear two flagella, the one long and slender, the other short 

 and strong, and ajjout half as long as the preceding one. The second antennae have only 

 one flagellum ; the outer portion of the upper margin of the hasal joint is two-toothed ; 

 the jjalp is moderately enlarged. The first two pairs of feet tire slightly developed and of 

 equal length ; each of them ends in a small didactyle hand. The second pair is shorter 

 than the tliird, and its carpos is inultiarticulate ; it ends in a very small didactyle hand. 

 The third pair of feet is the strongest. The upper margin of the third joint of the last 

 three pairs of feet ends in a small spine; the extremity of tlie fingers hears on its inferior
