bristles at base; 2nd joint with 3 annulate stout spinous bristles near 

 middle; 3rd joint elongate, recurved, with. 2 short, slender teniiinal 

 bristles and tip Avith ridges. 



Cuslunan (1906, pi. 28: fig. 11) erred in illustrating an endopodite 

 with 4 joints. Jones (1958a, p. 52) used the 4-jointed endopodite of S. 

 zostericola as one of the criteria for distinguishing that species from 

 S. tricostata, which has a 3-jointed endopodite. 



]M audible: coxale bare ^nthout endite; basale with 5 bristles 

 ventrall}^ and 3 dorsally (figs. 7h ; 86) ; endopodite has 1st and 2nd 

 joints each with, stout ventral claw with marginal spines and medial 

 surface with short spines (figs. 7i; So); 3rd joint with long stout 

 terminal b-claw with spines in 2 rows along proximal two-thirds and 

 short a-, c-, and d-bristles, c-bristles considerably shorter than a- 

 and d-bristles. 



The mandible of »S'. zostericola illustrated by Cushman (1906, pi. 

 28: fig. 12) differs from the above in having 3 medimn ventral bristles 

 and 5 dorsal bristles on the basale. The distribution of bristles on 

 the basale of the mandible of S. tricostata illustrated by Jones (1958a, 

 fig. 1-L) is similar to that in the above description. 



Maxilla (fig. Sc) : protopodite \Adth fringe of long hairs on margin 

 and 1 short bristle near middle; endite of protopodite with about 4 

 bristles; exopodite with 3 bristles; endopodite indistinctly segmented 

 with about 9 bristles. 



Fifth limb (fig. Sd): single endite with 1 spinose bristle; exopodite 

 has 1st joint with 2 spinose bristles; 2nd-5th joints not separated by 

 distinct sutures, with total of 7 bristles; epipodial appendage wdth 

 about 32 plimiose bristles (only base of distal 3 bristles shown in 

 figure) . 



Sixth limb (fig. Se): single endite with 3 short bristles; end joint 

 with about 10 hirsute bristles forming 2 rows separated by space 

 from 2 long hirsute posterior bristles, and with long hau's on posterior 

 margin and lateral and medial surfaces. 



Seventh limb not observed. Males of sarsiellids usually have at 

 least a short bare stump for a 7th Imib. The absence of a 7th limb, 

 however, was reported previously for the male of Sarsiella georgiana 

 Darby, 1965 (Darby, 1965). 



Furca: each lamella with 5 curved claws; claw no. 1 joined to 

 lamella; all claws with lateral and medial spines in row along each 

 side of concave margin; margin of left lamella posterior to 5th claw 

 mth about 10 small spines, right lamella with about 4 small spines; 

 anterior margin of each lamella above base of 1st claw with 2-3 

 minute spines. 



Frontal organ (fig. 8/) : elongate w^th rounded tip and 2 segments. 



Copulatory limb (fig. 8/0 : each limb consisting of a proximal and
