DIAGNOSIS Ovigerous 9 11.1-17.2 mm, 6 4.2-8.7 mm, transitional 9.6- 

 9.8 mm. Antennules and antennae consisting of four articles each. Uropods 

 short, not reaching posterior margin of pleotelson. Clavate copulatory stylet 

 present on pleopods 1-3 in S . Pleotelson basally broader than long, pos- 

 terior margin broadly rounded.

Lironeca Leach, 1818 



DIAGNOSIS Cephalon weakly to deeply immersed in pereonite 1; posterior 

 border rarely trisinuate. Bases of antennules not expanded, well separated. 

 Posterior pereopods with carinae on bases in 6 , carinae present or absent in 

 $ . Pleonites subequal in width; pleonites 1 and 2 rarely narrowed and

 with lamellar or digitiform accessory gills in some species. 



Key to species of Lironeca 



1. Uropodal endopod about twice longer than wide; pleon somewhat 



immersed in pereon redmanni 



Uropodal endopod about three times longer than wide; pleon barely 

 immersed in pereon tenuistylis

 Figure 83D 



DIAGNOSIS Ovigerous? 19.5-25.0 mm. Cephalon barely immersed in per- 

 eonite 1. Pleon somewhat immersed in pereon, but lateral margins of pleonite 

 1 free. Pleotelson basally wider than long. Uropodal rami reaching well be- 

 yond posterior margin of pleotelson; exopod longer than endopod, both rami 

 somewhat broad, endopod about twice longer than wide. Attaching to gills of
