NO. 35S0 OSTRACOD FAMILIES — KORNICKER 21 



present on this joint on slide no. 1900-3-6-452 containing a specimen 

 dissected by Brady and Norman. The 1st endopodite joint of 

 PhUomedidae usually contains more than 3 bristles, so it is probable 

 that Brady and Norman were unable to make an accurate count of 

 bristles on that joint. 



Mandible (figs. 106, c) : No coxale endite. Basale ventral margin 

 with 7 subequal bristles with wreaths of long hairs, some also with 

 short marginal spines distally ; dorsal margin with 1 bristle near middle 

 and 2 distally; sub ventral medial surface with 4 small proximal 

 bristles and 1 bristle proximal to middle. Exopodite reaching about 

 middle of 1st endopodite joint, with 2 subequal terminal bristles. 

 Endopodite 1st joint with 2 short and 3 long distoventral bristles; 

 2nd joint with 3 dorsal bristles proximally, 6 dorsal bristles near 

 middle, 2 ventral bristles subdistally and 2 long and 2 short ventral 

 bristles distally. End joint (fig. 106) with 2 large subequal claws, 

 1 short dorsal claw, and 4 bristles. Medial surface of basale and 1st 

 and 2nd endopodite joints with clusters of hairs. 



Maxilla (fig. lOd): Three endites: 1st endite with about 8 bristles; 

 2nd endite with about 7 bristles; 3rd endite with 1 proximal bristle 

 and numerous distal bristles. Coxale with long plumose bristle. 

 Exopodite with 1 short and 2 long bristles. 



Fifth limb (figs. lOe, g) : Epipodial appendage with about 33 bristles. 

 Three endites with numerous bristles. Exopodite 1st and 2nd joints 

 each with a flat, transparent, bladelike tooth and several bristles; 

 3rd joint with 2 stout plumose bristles on outer lobe and about 3 bare 

 bristles on inner lobe; 4th and 5th joints with 6 bristles. 



Sixth lunb (fig. 10/): Fu'st endite with 3 bristles; 2nd endite with 

 1 proximal and 3 distal bristles; 3rd and 4th endites each with 1 proxi- 

 mal and 7 distal bristles; end joint with 14 bristles; 3 plumose bristles 

 in place of epipodial appendage. Lateral and medial surface of end 

 joint with clusters of hairs. Some bristles of end jomt broken on 

 specimen examined. 



The description of the 6th limb given by Brady and Norman (1896, 

 p. 660) differs from the above. The 1st endite seems to have been 

 pulled off on Brady and Norman's dissected specimen (slide no. 1900- 

 3-6-452), but part of 1 bristle remains to show that the endite was 

 present. The missing 1st endite on the specimen evidently led Brady 

 and Norman to mistakenly consider the 2nd endite to be the 1st 

 endite, the 3rd endite to be the 4th, and the 4th to be part of the end 

 joint. Brady and Norman described the 1st lobe [then- termmology] 

 to have 2 setae, and the 2nd lobe to have 1 lateral and 6 distal setae 

 The dissected specunen (slide 1900-3-6-452) actuaUy has 1 lateral 

 and 3 distal setae on the 1st lobe [their terminology] and 1 lateral and 

 7 distal setae on the 2nd lobe. The remainder of the description of
