teeth nine to ten in number, veiy small, rounded, fairly regular as to size, 

 shape and spacing, being farther apart basally; bear a few small secondaiy 

 teeth on caudal edge, margin of valve between teeth also notched with small, 

 numerous secondary teeth; tip notched with small teeth on both dorsal and 

 \entral edges, not continuous around the tip, about fifteen present on the 

 ventral edge; area of ducts conspicuous, granular in appearance, though elon- 

 gate ducts are visible; duct openings visible; open along ventral apical edge, 

 at extreme apex, along dorsal edge of toothed area, and in basal region, where 

 many elongate ducts are visible; the two valves of the pair are joined one to 

 the other by a distinct, elongate, curved, heavily chitinized connection present 

 on the dorsal edge of the basal area; this connection bears a rounded promi- 

 nence toward the caudal end. 



Euscelis comma (Van Duzee). 



(PI. XXIII, fig. 13; pi. XXXI, fig. 4.) 



Length, 1.5 mm.; greatest width, 0.22 mm. About the same width for entire 

 length beyond curved basal connection, tapers caudad to apex; no preapical 

 prominence; only slightly curved, tip narrowed by broadly curving ventral 

 edge, extreme apex narrowly rounded, chitinization rather heavy; strengthen- 

 ing rod extends caudad to within a short distance of apex. Toothed area 

 on dorsal edge occupies a little less than the apical half; teeth numerous, 

 small, roimded, veiy irregular as to size, shape and spacing and present an 

 irregularlj' crenulate margin; tip bears no distinct teeth but is irregularly 

 roughened; area of ducts conspicuous, granular in appearance, with many 

 elongate ducts visible; open along ventral apical edge, at extreme apex, along 

 doi-sal edge of toothed area, and in the basal region where many elongate ducts 

 are visible; the two valves of the pair are joined one to the other by an 

 elongate, distinct, heavily chitinized connection present on the dorsal edge of 

 the basal area; it is a little less than half the entire length and at the point 

 of greatest width is about one-half the width of the valve; bears an indistinct, 

 broadly rounded prominence a little caudad of the midpoint. 



Euscelis curtfsii (Fitch). 



(PI. XXXI, fig. 5.) 



Length, 1.1 mm.; greatest width, 0.12 mm. Apical half slightly wider than 

 basal half, bears no preapical prominence ; only slightly curved beyond curved 

 basal attachment, gradually narrowed, ends in narrowly rounded extreme apex, 

 chitinization moderatelj' light; strengthening rod extends caudad as far as 

 next to last dorsal tooth. Toothed area on dorsal edge occupies the apical 

 half; teeth fourteen to sixteen in number, small, rounded, fairly regular in size, 

 shape and spacing, though not entirely so; bear a few secondar.v teeth on the 

 caudal edge and an occasional secondary tooth on the cephalic edge; tip notched 

 with small teeth on ventral edge onh', dorsal edge devoid of teeth at extreme 

 apex, ten present on ventral edge; area of ducts conspicuous, granular in ap- 

 pearance, openings visible; open along ventral apical edge, at extreme apex, 

 along dorsal edge of toothed area, and in basal region where elongate ducts are 

 visible; the two valves of the pair are joined one to the other by a distinct, 

 elongate, slightly curv-ed, chitinized connection present on the dorsal edge of 

 the basal area.
