Three to foursmall teeth arc intercalated between teeth that are conspicuouslystouter.Measuremcnts of figured specimens: length 16.4 mm., height atproximal tooth 1.9 mm., thickness at proximal tooth 1.1 mm., 23 teethin 11 mm. (WFIS 17093) ; length 12.4 ram., height 1.9 mm., thickness0.9 mm., 17 teeth in 8.5 mm. (WFIS 17094).Remarks.--The smooth concave area behind the proximal occludenttooth serves to distinguish the dactylus of this species from that of O.coesfeldiensls (Schluter, 1862, p. 728, pl. 13, figs. 3, 6 ; Senonian ; northwesternGermany).A specimen from the Matawan beds at the C. and D.
