Figure 2 



Male pleopods (pi); mesial views of pi 1 (slight lateral folds on tips not shown in these views), and mesial views of appendix 

 masculina on mesial ramus of pi 2: (a and 6) Homarinus capensis, left (USNM 251452); (c and d) Homarus americanus, right 

 (USNM 13952); (e and f)H. gammarus, right (USNM 2085). Scale is 1 mm; bar 1 applies to c through f\ bar 2 applies to a and 6. 



linguiform in dorsal view, broad at base where mar- 

 gins coalesce with orbits, margins bearing 4-6 small 

 spines and gradually tapering anteriorly to rather 

 abruptly pointed or narrowly rounded tip, reaching 

 distal 1/3 of penultimate article of antennular peduncle, 

 shallow dorsal concavity running its entire length. 



Telson and uropods with thick fringe of plumose 

 setae on distal margin and with scattered non- 

 plumose long setae dorsally on these appendages and 

 sixth abdominal segment. Telson as wide at base as 

 long, with lateral margins slightly sinuous and 

 subparallel bearing obsolescent spines and rugae, 

 each side ending in fixed posterolateral spine; ter- 

 minal margin beyond spine broadly convex; distal 

 1/3 of surface bearing obsolescent transverse rugae. 

 Uropods broadly subovate, sparsely setose on dorsal 

 surface; mesial ramus broadest near posterior mar- 

 gin with width about 0.73 length, row of obsolescent 

 lateral marginal spines ending in fixed posterolat- 

 eral spine; lateral ramus with width about 0.72 

 length, diaresis well behind midlength bearing row 

 of fixed but irregularly worn spines ending in stron- 

 gest spine at posterolateral angle. 



Chelae of first pereopods with thick coat of long 

 plumose setae on upper surface of palm, overhang-

ing extensor margin and distributed a distance along 

 fixed finger; similar setae on mesial surface of car- 

 pus and ventral surface of merus. Fingers not gap- 

 ing; those of major chela with crushing teeth (often 

 worn) opposed from near base to about midlength
