 ones on outer margin. 



Second maxilla, apices of lobes strongly setose with 9 strong spines 

 on outer plate and 11 on inner, arranged irregularly. 



Maxilliped as figured for L. aestiva, but the apices of the lobes of 

 inner plate blunter. 



First and second gnathopods as in L. aestiva. 



First and second peraeopods 18 mm. long, 2nd joint longest, 5 mm., 

 4th and 5th each 4 mm., 6th 4'5 mm.

The first gnathopod very feebly spinulose, the 2nd and all the 

 peraeopods neither spiuulose nor setose. 



Branchial lamella of 2nd gnathopod and 1st peraeopod very small, 

 1 mm. long ; that of remaining peraeopods 4-5 mm. long, oval, non- 

 setose.
