margin of telson fork bearing 6 spines of approxi- 

 mately the same length. 



AN1 (Figure 2C) — Uniramous, unsegmented, 

 and conical with 2 long aesthetascs, 2 smaller aes- 

 thetascs, and one simple setae on the terminal 

 end. 



AN2 (Figure 2D) — Protopodite long, ending in a 

 point with 2 rows of spinules distally, small en- 

 dopodite bud near base. Exopodite long, spinulose 

 distally; 2 small spines just subterminal, inner- 

 most spinulose. 



MAX1 (Figure 2F) — Endopodite 2-segmented; 

 proximal segment with 1 long simple or sparsely 

 plumose seta, distal segment with 4 terminal 

 setae (2 plumose, 2 plumodenticulate) and 1 sub- 

 terminal plumose seta. Basal endite with 4 

 plumodenticulate cuspidate and 2 plumodenticu- 

 late terminal setae and 1 subterminal plumose 



seta; smaller coxal endite with 5 plumose setae 

 and 2 simple setae. 



MAX2 (Figure 2E)— Scaphognathite with 9 

 plumose marginal setae and a plumose apical tip. 

 Endopodite simple with 4 (rarely 5) terminal 

 plumodenticulate setae and 1 simple seta. Basal 

 endite slightly bilobed; 4-5 plumodenticulate 

 setae on distal lobe and 5 (rarely 4) plumodenticu- 

 late setae on proximal lobe. Coxal endite bilobed; 

 3-4 plumose setae on distal lobe and 4 plumose 

 setae on proximal lobe. 



MXP1 (Figure 2A)— Exopodite with 4 long, 

 plumose natatory setae. Endopodite 5-segmented; 

 setation formulae (proximal to distal): 3, 2, 1, 2, 5. 

 Terminal segment with 5 setae (4 multidenticu- 

 late and 1 short, simple). Basiopodite with up to 9 

 setae. 



MXP2 (Figure 2B)— Exopodite with 4 plumose
