182 CRETACEOTJS FOSSILSJersey, erroneonsly identified with A''. pierrensis by Rathbuln (1935,1). 45, pl. 12: fig. 5) clearly sho~v that the row of gastric tnbercles is conrcsfor\varrl and that the uro- and metagastrie tnbereles are mach morest,rongly dercloped than in N. pierrensis.Dktribzitiolr ill.

Frontoorbital distance about one-halftlle carapacal 1~idt11. Orbits almost transverse, slanted upward, ocularrim broad, convex, curving upward and outward from the orbit. Anterolateralmargin deeply concave in lateral profile, provided with fourteeth behind the outer orhital angle. Epibrancl~ial tooth conical andhlunt, directed obliquely upward and forward and situated twice as farfrom the fourth anterolateral tooth as t.hc latter is separated from thet,hird :~nterolateral tooth. Second, third and fourth anterolateral tcetl~spacer1 equally. Anterior half of postcrolateral margin armed withthree teet,h, the first tootli larger than the second and tl~ird and situatedmidway between the epibranehial tooth and the second tooth. Halfwayhetween the shallow uro-metagastrie furrow and the orbit thereis a transverse line of four conical tubercles. There are two of t,hes~:l.uhercles on each protogastric boss and the inner pair of tubercles ismuch larger than t,l~e outer pair. Urogastric field depressed and armedwith a small median tubercle. Cardiac field subhexagonal, elevatcrl:limitetl laterally by deep, natro\tr branchioenrdiac grooves, ant1 with ;Itransverse, submedian pair of conical tubercles at the middle. 111-tcstinal fielil short, depressed, a small transverse tubercle at each 110steriorangle. Hepatic field concavel unarmed, sloped doxvnmard tolvarrlthc margin of the carapace. B boss surmounted by a longitndinall?elongated tubercle occupies the inner angle of the epibrancliial region.This elongated tuhercle points to a small epibranchial t,uberclc mhicl~lies just behind the outer extremity of the cer~~ieal groove. Dorsal surfaceof carapace finely and rather evenly granulate, hut !vith a fewlarge scattered granules on the brancl~ial fielil.Bfeasnrcment of holotype: length of earapace measured from baseof rost,rnnl 12.3, greatest midth 14.5, frontoorl~ital width, 7.3 mm.Ren~arks.-This species resembles P.
