 ate sized spines in basal endite; 

 endopod 5-segmented; exopod 

 with 24 plumose natatory setae. 

 Third maxilliped (Fig. 2H) En- 

 dopod 5-segmented, armed with 

 many spines; exopod of 36 plu- 

 mose natatory setae.

 unchanged from 2 nd pereiopod 

 through 5 th pereiopod. 

 Pleopods (Fig. 2N) Bilobed 

 buds, not functional; no seta and 

 hair on buds; no further devel- 

 opment from the 1 st stage.
