as thick in the middle, rounded dorsally. Telson a little longer than 

 6 th somite, with 2 pairs of dorso-lateral spinules, and with 3 spines at 

 either side of the acute apex. 



Eyes large, dark purplish, greatest diameter l / G the length of carapace. 



Lateral process of antennular peduncle lamelliform, rounded, a little 

 shorter than basal joint. Joints of upper flagellum all longer than broad. 

 Antennal scale one-third the length of carapace, twice as long as broad, 

 outer margin straight, unarmed, terminal spine not or hardly exceeding the 

 moderately broad, distal border of the lamella, antero-internal angle obtuse. 



First pair of peraeopods slender; propodus of subchela half as long 

 as the carapace, rostrum included, slender, 4,8 -times as long as wide in 

 the middle. Carpus of 2 nd legs a little shorter than chela, palm slightly 

 broader than long, fingers 3-times as long as palm. Carpus of 4 th pair 

 2,5-times as long as broad, propodus 1,7-times as long as carpus, dactylus 

 half as long as propodus, slender, nearly straight. 



Exopodite of 2 nd pleopod 4,7-times as long as broad, endopodite little 

 more than half as long and 5-times as long as broad, no stylamblys. 



The other specimen is shorter, 14 mm. long, carapace 3,8 mm., ab- 

 domen 10,2 mm. In proportion to the carapace the abdomen, the 6 lil 

 somite and the telson are a little shorter, the 6 tl1 somite a little thicker; 

 it differs, however, more really by the 1 st or uppermost lateral spine of 

 the carapace wanting completely, by the stouter shape of the anterior 

 peraeopods (propodus not yet half as long as carapace and S^-times as 

 long as wide in the middle), by the anterior margin of the rostrum being 

 slightly concave and by the gastric spine being produced backward in 

 an obtuse carina, that reaches to just behind the middle of the carapace, 

 though not prominent at all.
