Table 2. — Comparison of species descriptions of Pachycheles rudis. 



^ Most common occurrence in bold face. 



Maxilla I with indistinctly two-segmented 

 endopodite bearing two stout setae on distal seg- 

 ment. Basal endite with 8 long, slender and 16 

 stout, spinous setae on margin and 6 short setae 

 on ventral surface. Coxal endite with about 

 26 marginal setae and 4 fine setae on ventral 

 surface, Coxal exite present as delicate fleshy 

 lobe rimmed with fine hairs. One proximal seta 

 on appendage near articulation with gnathal 

 skeleton. 



Maxilla II with large numbers of setae. En- 

 dopodite unsegmented with five setae. Basal 

 endite bilobed: distal lobe with about 35 setae; 

 proximal lobe with 9 or 10 marginal and 4 sub- 

 marginal setae. Coxal endite bilobed: distal 

 lobe with 20 to 21 setae arranged as figured; 

 proximal lobe with 30 to 35 setae arranged as 

 figured. Scaphognathite with about 58 setae 

 around the margin and 2 fine submarginal setae 

 on the anterior lobe. 



Maxilliped I with numerous setae. Exopodite 

 fleshy with one seta on margin. Endopodite in- 

 distinctly two-segmented, bearing a single seta 

 proximally. Protopodite produced into trian- 

 gular lobe with about 35 to 45 marginal setae 

 and 3 proximal setae as figured. Coxal lobe 



with a total of about 18 setae arranged as fig- 

 ured. 



Maxilliped II biramous. Setation of coxopo- 

 dite and basipodite variable, approximately as 

 figured. Exopodite two-segmented with setae 

 as figured, with eight or nine setae on terminal 

 segment. Endopodite with four segments; seg- 

 ments 3 and 4 having distal brushes of short 

 setae numbering about 24 to 28 and 16 to 20 

 respectively. Other setation as figured. 



Maxilliped III biramous. Exopodite two-seg- 

 mented but incompletely formed. Segments 2 

 through 5 of endopodite equipped with major 

 feeding setae; segment 2 with 11 or 12 feeding 

 setae of two lengths, dorsal margin; segment 3 

 with five or six feeding setae on ventral margin, 

 seven feeding setae or dorsal margin, and seven 

 brush setae of varying lengths; no spikelike 

 setae on dorsal protuberance; segment 4 with 2 

 short setae, 5 major brushes and 4 spike setae 

 on dorsal protuberance, 10 long feeding setae 

 on ventral margin, and 9 scattered minor sub- 

 marginal setae on ventral surface; segment 5 

 with 10 or 11 marginal setae and 2 or 3 short 

 terminal setae. Other setation as figured.
