STALK-EYED CRUSTACEA 133 



these lobes a granular transverse line. There is a similar 

 line upon the epibranchial lobes ; it is arranged a littlc 

 obliquely from before backwards. A small granular crest 

 takes its origin at the base of the last lateral tooth, and 

 it extends a short distance upon the mesobranchial lobe. 

 The surface of the carapace is covered, in all its antero- 

 lateral portions, with fine granulations. The front is 

 advanced, almost horizontal ; its inferior border is granular 

 and slightly notched laterally. The orbit is large, and 

 the two fissures of the superior orbital border are well 

 marked. The external orbital angle is separated from the 

 second antero-lateral tooth by a round notch, and these 

 two teeth appear to form a single lobe. The third tooth 

 has a wider base than the fourth ; the fifth is the smallest, 

 more pointed, and, in place of being flat, is in the form of 

 a triangular pyramid. The inferior orbital border has 

 on the outside a wide hiatus, and its internal angle is 

 produced into a prominent tooth ; its middle portion is 

 fine and straight. There is a subhepatic tubercle below 

 the second lateral tooth. The pterygostomian regions are 

 finely granulated and slightly hairy. 



The first pair of legs strong and of unequal size. 

 The fourth joint is completely hid under the carapace ; 

 its posterior border is cristiform, and it has two teeth near 

 its extremity. The forearm is a little rough, and it is 

 armed on the outside with a large tubercle. The hand 

 is swollen and smooth or slightly rough. The larger has 

 strong fingers, and at the base of the movable finger 

 there is a large round tubercle. The fingers of the small 

 pincer are thin, almost straight and scarcely dentated. 

 The walking legs are feeble, and hairy towards their 

 extremities. 



The colour is red or yellow, with the legs of a dark or 

 brown shade.
