412 STALK-EYED CRUSTACEA 



four spines arranged in pairs, the one before the other ; 

 the cardiac region has four spines, one pair, large, in 

 front ; the other, small, behind. The sides posteriorly 

 have in front three strong spines; there is a short spine 

 between the first and second. The branchial regions 

 have laterally three spines, shorter and arranged longi- 

 tudinally. The rostrum is almost as long as the internal 

 antennae ; towards the middle of its length it gives origin 

 on each side to a small point in such a way as to appear 

 trifurcate, the middle point being longest. The second 

 and third segment of the abdomen carry four or six 

 spines arranged transversely. These points exist, but 

 slightly marked, on the fourth segment. The first pair 

 of legs long; the fourth and fifth joint have spines ; the 

 hand is unarmed. In the female the fingers are in contact 

 in their whole length when closed ; in the males, only at 

 their extremities. The walking legs are spinous.

 spines. There are six short symmetrically arranged 

 spines on the posterior edge. The rostrum is straight, 

 and the two lateral points are very small and directed 

 forwards. The second and third abdominal segment 

 have three spines ; the fourth has none.
