138 STALK-EYED CRUSTACEA 



slightly wavy border ; its lateral angles are teeth-like, 

 but not projecting much. The superior orbital border is 

 interrupted by two small fissures ; the external orbital 

 hiatus is narrow, and the internal suborbital angle is 

 distinct from the rest of the floor of the orbital cavity. 

 The antero-lateral edges are cut into four truncated and 

 tooth-like lobes. The external orbital angle and the 

 second lobe counting as one. The division between 

 the two first is a fissure, that bet\t'een the other lobes, a 

 notch. The latero-inferior regions are granular, and the 

 subhepatic tooth is scarcely visible. 



The legs of the first pair are of unequal size; that of 

 the right side is much swollen and smooth. It has 

 strong fingers ; the movable finger has a strong basal 

 tooth. The walking legs are thin.

The carapace is naked ; it is slightly convex, and the 

 regions are distinctly lobulated, especially in front. The 

 front is wide, and is formed of two lobes with a more or 

 less rounded outline. The orbits are directed forwards, 

 and their superior border is either entire or interrupted 

 by two very small fissures. The antero-lateral border 

 is short and armed with many teeth, but the second 

 tooth is usually soldered with the orbital angle, which is 

 slightly prominent; the posterior tooth is very small. 

 The basal antennal joint is fastened, at its internal angle, 

 with the subfrontal prolongation. The antennulary 

 fossffi are hollowed out almost transversely under the 

 front. The endostome may have, on each side, a feeble
