two on the vent ml cnlge; ducts consijicuous, rather numerous, elongate, slightly 

 curved, most numerous apicalh-; open apically, along dorsal edge in and near 

 teeth, and in the .•^in-face of the valve back from edge. 



Drceculaccyh a la n o ve boracensu ( Fitch ) . 



(PI. XXVII, fig. 1.) 



Length, 2.65 mm.; greatest width, 0.33 mm. Narrow and rodlike at base, 

 broad and flat ajiically, apical shaft about the .same width for entire length; 

 prcapical prominence wanting; only slightly curved beyond base, tip greatly 

 narrowed by slightly curving dorsal edge and greatly curving ventral edge 

 and ends in a rather sharp point, chitinization light, much lighter than in the 

 other members of this genus examined; strengthening rod extends cavidad to 

 a point midwaj' between last dorsal tooth and apex. Toothed area on dorsal 

 edge occupies entire length of apical shaft, the dorsal edge bearing the teeth 

 more heavilj^ chitinized than the rest of the valve; teeth thirty-nine to forty- 

 one in number, of medium size, the basal sixteen of a general triangular shape, 

 the apical twenty-three subquadrate wath the cephalic side longer than the 

 caudal, rather irregular in size, shape, and spacing; the basal triangular teeth 

 bear small secondary teeth on both dorsal and ventral edges; the apical sub- 

 quadrate teeth bear three to twelve secondary teeth on the outer edge and 

 two to five on the cephalic edge; the secondary teeth midway of the valve 

 are very small and indistinct; tip notched with small teeth on both dorsal 

 and ventral edges, not continuous around the tip, forty-five present on the 

 ventral edge; ducts inconspicuous, very faintly visible except at openings, 

 rather numerous, most numerous apically; open apically, along dorsal edge 

 in and near teeth, and in surface of valve back from edge. 



Drceculacephala reticulata (Signoret). 



(PI. XXII, fig. 12; pi. XXVII, fig. 3.) 



Length, L75 mm.; greatest width, 0.27 mm. Basal portion narrow and rod- 

 like, apical portion broad, fiat, about the same width for entire length, nar- 

 rows at apex; preapical prominence wanting; not curved beyond curved basal 

 attachment, tip greatly narrowed by slightly .curved dorsal edge and greatly 

 curved ventral edge, ends in obtuse point, chitinization medium, less heavy 

 than in D. noveboraccnsis and heavier than in D. mollipes; strengthening rod 

 extends caudad to a point midwaj^ between last dorsal tooth and apex. 

 Toothed area on dorsal edge occupies apical shaft for entire length; teeth 

 twenty-six to twenty-eight in number, rather large, basal eleven of a general 

 triangular shape, apical fifteen subquadrate with the cephalic side longer 

 than the caudal, rather irregular in size, shape and spacing; basal eleven bear 

 small secondai-y teeth on both edges; apical subquadrate teeth also bear sec- 

 ondary teeth, three to eleven on the outer edge and, with the exception of 

 the apical three, one to five on the cephalic edge; tip notched with small 

 teeth on both dor.sal and ventral edges, not continuous around the tip, 42 pres- 

 ent on the ventral edge; ducts conspicuous, rather straight, numerous, most 

 numerous apically; open apically, along dorsal edge in and near teeth, and a 

 few in the face of valve back from edge.
